As Stephen said in the blog post, Task.Run is equivalent to:
Task.Factory.StartNew(someAction, CancellationToken.None, TaskCreationOptions.DenyChildAttach, TaskScheduler.Default);
It is possible to get proper async support in LINQ to SQL, although it's not perfect. For example:
public static async Task<List<T>> ToListAsync(this IQueryable<T> query, DbContext context, CancellationToken cancellationToken = default)
{
if (query is null) throw new ArgumentNullException(nameof(query));
if (context is null) throw new ArgumentNullException(nameof(context));
using (var command = (SqlCommand)context.GetCommand(query))
{
await command.Connection.OpenAsync(cancellationToken);
using (var reader = await command.ExecuteReaderAsync(CommandBehavior.CloseConnection, cancellationToken))
{
return _context.Translate<T>(reader).ToList();
}
}
} DataContext.GetCommand(IQueryable) Method (System.Data.Linq) | Microsoft Docs[^]
DataContext.Translate Method (System.Data.Linq) | Microsoft Docs[^]

OK, so I'm using Linq to SQL. What more can I do to make the method async? The Command has the ExecuteReaderAsync method, but my Linq to SQL code won't have any of that. For example:
public Task<List<ReportData>> GetReportData(ReportArgsEntity args)
{
var t = Task.Run(() =>
{
var results = new List<ReportData>();
using (var dc = GetDataContecxt())
{
results = (from c in dc.Companies
join ih in dc.InvoiceHeaders on c.Id equals ih.CustomerId
join id in dc.InvoiceDetails on ih.Id equals id.HeaderId
where c.Completed
select new ReportData
{
}).ToList();
}
return results;
});
return t;
}
If it's not broken, fix it until it is.
Everything makes sense in someone's mind.

Use the extension method from my previous post. For example:
public async Task<List<ReportData>> GetReportData(ReportArgsEntity args)
{
await Task.Yield().ConfigureAwait(false);
var query = from c in dc.Companies
join ih in dc.InvoiceHeaders on c.Id equals ih.CustomerId
join id in dc.InvoiceDetails on ih.Id equals id.HeaderId
where c.Completed
select new ReportData
{
};
return await query.ToListAsync(dc);
}

I see.
The whole reason I'm asking is that right now all of the code is on the UI thread. But we're going to be moving the BL & DAL to Controllers in an ASP.Net Web API. So the UI will need to fire & forget each call and await the results.
Given that, and other that what we've already discussed, any reason this wouldn't work?
If it's not broken, fix it until it is.

The Web API action can be async, so this code will just work as-is. You might want to drop the Task.Yield line though, since you're not worried about blocking the UI thread.
The client code can make async requests to the web API - how easy that is will depend on which library you're using to call it. Using async and await will ensure that the UI thread isn't blocked whilst you're waiting for a response from the network.

I am storing jSon string as hexa-decimal or some characters string, its all working fine whan I retrieving as json string in my code, but there is one field I want to remove from the jSob object after I retrieved.
var t = StoredProcedures.SP_GlobalSearch.Execute(new SP_GlobalSearch_Params
{
Search = request.search,
SourceKey = "",
Skip = start,
Take = length,
ShowDeleted = false
}).Select(x => new SP_GlobalSearch
{
JsonObject = x.Data != null ? new JavaScriptSerializer().DeserializeObject(x.Data.Replace("", "")) : null,
Date = x.Date,
JsonObjectId = x.JsonObjectId,
SourceKey = x.SourceKey,
SourceId = x.SourceId,
TotalCount = x.TotalCount
});
var response = t?.ToList();
var jsondata = new DataTableResponse<SP_GlobalSearch>
{
totalCount = (int)response.Where(x => x.TotalCount != null).FirstOrDefault().TotalCount,
data = response.Where(x => x.TotalCount == null)
};
var jsonResult = Json(jsondata);
jsonResult.MaxJsonLength = Int32.MaxValue;
return jsonResult;I am reading the text as jSon with the below statement,
JavaScriptSerializer().DeserializeObject(x.Data.Replace("", ""))

I want to remove the Violations part from the jSon object, can you please help me in this regards thank you.

You can't "remove" the violations from the JSON once you have read it: either it's still in the JSON string (in which case you probably want to look at a Regex or similar to remove fit from that) or it's a part of the InspectionItem class and the best you can do is set the InspectionItem.Violations property to null for each instance in your data.
You can't "delete" a property from a class after compilation!
Probably the best way would be to use a Regex to remove the Violations section from the JSON source before you deserialize it - but there could be some significant work involved in writing that, given that the sample you show does not contain any data in the Violations section, so we have no idea how complicated that JSON clause might be when filled in. Complicated clause == complicated Regex!

Yeah making that property value null is fine - can you please help me in this regards please? Or can you please help me with the Regex please? Thank you.

|

You don't know how to set a property?
Why are you playing with JSON if you don't know the (very, very) basics?

To answer this we need to know the type of SP_GlobalSearch.JsonObject. If it's something like a InspectionResult class or even a dynamic, then it's simple:
var response = t==null? null : t.Select(r=>{r.InspectionItems.Violations = null; return r;}).ToList();
If JsonObject is a System.Object, then things get messy. Best to change than to one of the options given above.

I have been away from Windows desktop development environment (Using C++ MFC) for many years.
Recently, I plan to port an Android app to Windows desktop environment.
I plan to use C# as my tech stack.
However, I have 0 clue on how to develop a
- Card liked UI dashboard
- Achieve drag-n-move animation
Our Android app looks like - Drag and move animation - YouTube[^]
Do you have any suggestion library, which can help me to implement so?
Thank you.
|
|
|
|
|
|
In the video, it shows how "Card liked UI dashboard" look like.
Also, this is a JavaScript implementation of "Card liked UI dashboard" - Column grid demo[^]
As you can see, the JavaScript example supports drag-n-move, and resizing.
Any idea on where I can get an equivalent C# desktop library to implement such?
Thanks.

If you want a ready made lbrary then Google is the place to search. Or you could just write your own code to move things around on a form.

Hello Everyone,
I'm currently trying to fetch data from 1 excel workbook, which is having multiple sheets
Please find my excel sheet: here
Please find my code to get the excel data
<pre>public static T GetAllTestData<T>(string keyName)
{
using (var connection = new
OdbcConnection(TestDataFileConnection()))
{
connection.Open();
System.Data.DataTable dt = null;
dt = connection.GetSchema(OdbcMetaDataCollectionNames.Tables, null);
String[] excelSheets = new String[dt.Rows.Count];
var i = 0;
foreach (DataRow row in dt.Rows)
{
excelSheets[i] = row["TABLE_NAME"].ToString();
i++;
}
T value = default(T);
for (int j = 0; j < excelSheets.Length; j++)
{
var query = string.Format("select * from [{0}] where TestName = '{1}'", excelSheets[j], keyName);
value = connection.Query<T>(query).FirstOrDefault();
}
connection.Close();
return value;
}
}
Call to the function:
var param1 = AccessExcelData.GetAllTestData<TestDataModel>("Test1");
Issue:
I want to get all the values from all the sheets in excel which has TestName as "Test1" but in my method, variable value keep getting override which makes it tough for me to get all the values
Can someone look into this, or If I can have another approach for handling excel data test in c#
|
|
|
|
|
Your problem is in the following loop ...
for (int j = 0; j < excelSheets.Length; j++)
{
var query = string.Format("select * from [{0}] where TestName = '{1}'", excelSheets[j], keyName);
value = connection.Query<T>(query).FirstOrDefault();
}As soon as you have got a value in the value field, you move on to the next sheet. You need to either do something with the value before going round the next iteration of the loop or store the values (one per sheet) e.g. in an array, and then process them all together after completing the loop.

Hello,
I wanted to recover data from an oracle 9i database. I work on 64 bit systems.
I downloaded the driver ODAC112040Xcopy_64bit in which I found .dlls (among which there is Oracle.DataAccess.dll) that I added them to a windows console application under visual studio 2012 and I added Oracle. DataAccess.dll as a reference in the application. So it works for recovery.
Now, I wanted to create a web service to do this recovery.
So, I created a project of type "ASP.NET Empty Web Application" for I added an element of type web service just that displays by default "Hello Wrold". When I compile and run the application then I get the following message:
Bonjour,
Je voulais récupérer des données à partir d'une base des données oracle 9i. Je travail sur des systèmes de 64 bit.
J'ai téléchargé le driver ODAC112040Xcopy_64bit dans lequel j'ai trouvé des .dll (parmi lequel il y a Oracle.DataAccess.dll) que j'ai les ajouté à une application windows console sous visual studio 2012 et j'ai ajouté Oracle.DataAccess.dll comme référence dans l'application. Alors ça marche pour la récupération.
Maintenant, je voulais créer un web service pour faire cette récupération.
Alors, j'ai crée un projet de type "ASP.NET Empty Web Application" pour j'ai ajouté un élément de type web service juste que affiche par défaut "Hello Wrold". Lorsque je compile et j’exécute l'application alors j'ai le message suivant :

This is an English language site, and we can only answer questions posted in that language. Please use Google Translate to convert your message before posting in future.
But the error message is pretty clear:
Unable to load file or assembly 'Oracle.DataAccess' or one of its dependencies. An attempt was made to load an incorrect format program.
At a guess, the Oracle DB engine is missing (or at least partially missing), configured for 32 bit when the system is 64, or vice versa, etc. Eitehr way, this isn;t somethign we can really help you with.
Start by contacting your hosting service and ask them if they have had this problem before - they may be able to shortcut the process of working out exactly what you have done.
Il s'agit d'un site en anglais et nous ne pouvons répondre qu'aux questions publiées dans cette langue. Veuillez utiliser Google Translate pour convertir votre message avant de poster à l'avenir.
Mais le message d'erreur est assez clair:
Impossible de charger le fichier ou l'assembly 'Oracle.DataAccess' ou l'une de ses dépendances. Une tentative de chargement d'un programme au format incorrect a été effectuée.
À une supposition, le moteur Oracle DB est manquant (ou au moins partiellement manquant), configuré pour 32 bits lorsque le système est à 64, ou vice versa, etc. De toute façon, ce n'est pas le cas, nous pouvons vraiment vous aider.
Commencez par contacter votre service d'hébergement et demandez-leur s'ils ont déjà rencontré ce problème - ils pourront peut-être raccourcir le processus d'élaboration de ce que vous avez fait.

When you get a BadImageFormat exception, it usually means you're trying to mix 32 and 64-bit code in the same process.
From your description, you are probably trying to use a 64-bit .DLL in a 32-bit app, or your code is running as 32-bit instead of 64.

Considering you never said what change you made and what the IIS app and app pool settings currently are, there's nothing anyone can tell you.
