Re: Deserealize a binaryformtted string - C# Discussion Boards

25-Sep-12 2:11

Sorry if this posted more than once.

I have a method that creates this value:
0x0001000000FFFFFFFF01000000000000000601000000036162630B
It is stored in the DB as <Binary Data>.

I use Select value from table where id = 1234.

This is the code that writes creates the value:
<pre>
public void SetSessionData(string token, object data)
{
DataService ds = null;
try
{
ds = new DataService();
using (MemoryStream stream = new MemoryStream())
{
DALArgs args = new DALArgs();
ds.SetRealmConnection(_realm);
Args.Add("sessionkey", _sessionkey);
args.Add("sessiontoken", token);
BinaryFormatter b = new BinaryFormatter();
b.Serialize(stream, data);
stream.Position = 0;
byte[] buffer = new byte[stream.Length];
stream.Read(buffer, 0, buffer.Length);
args.Add("sessionvalue", buffer);
ds.Execute("olb_SetSessionData", args);
</pre>

I'm trying to figure out how I can assign the results of the select statement to a variable and create this response:

0
1
0
0
0
255
255
255
255
1
0
0
0
0
0
0
0
6
1
0
0
0
3
97
98
99

That array comes from this:

<pre>
if (reader.Read())
{
byte[] data = (byte[])reader["SessionValue"];
<pre/>

I hope that is enough information, and that it can be done.

Any help is appreciated.

That'd be accepted if it were accidental; however, you copied/pasted your complete question, bumping your request. That's not done - your question is not more important than the others.

Most of the examples on serializing come with an example on deserializing. And mostly, it is separated from the rest of the logic; meaning that you serialize/deserialize an object, without a reference to a database.

Can you please edit the question and include your serialization routine? Your deserialization-code will be based on that.

This is the seralization code:

BinaryFormatter b = new BinaryFormatter();
b.Serialize(stream, data);
stream.Position = 0;
byte[] buffer = new byte[stream.Length];
stream.Read(buffer, 0, buffer.Length);

//Clear mp for further usage.
mp = null;
            
//Open the file written above and read values from it.
stream = File.Open("EmployeeInfo.osl", FileMode.Open);
bformatter = new BinaryFormatter();
        
Console.WriteLine("Reading Employee Information");
mp = (Employee)bformatter.Deserialize(stream);
stream.Close();
            
Console.WriteLine("Employee Id: {0}",mp.EmpId.ToString());
Console.WriteLine("Employee Name: {0}",mp.EmpName);

Taken from this[^] article, your code would look something like below;

BinaryFormatter b = new BinaryFormatter();
using (Stream s = File.Open("EmployeeInfo.osl", FileMode.Open))
{
   return (MyType)b.Deserialize(s);
}

Thanks Eddy, I'll give that a try.

Eddy Vluggen25-Sep-12 4:44

You're welcome.

I'd try it in a separate console-app, and move it to the "current" app that your working on once it works. It helps to keep the samples as small as possible, making sure that none of the other code interferes. Once you're used to that, it's a small step to writing (unit) tests.

Don't you see that the value you presented is just 0x followed by the hexadecimal representation of each of the numbersou listed followed by 0b?

Member 928312225-Sep-12 4:01

25-Sep-12 4:01

Thanks for the response Bernhard. How does FF translate to 255?

Bernhard Hiller25-Sep-12 4:09

Bernhard Hiller

25-Sep-12 4:09

Hexadecimal - you have "digits" from 0 to 15, 10 becomes "A".
So to translate back, "F" means 15, "FF" is just 15*16 + 15.

Re: how to export these names as rows to excel

Select all, press Ctrl-C, Ctrl-V and you're there.

It does not matter "which" names you try to import, strings are all alike. I suggest you search an article on exporting "data" to excel and give it a try - if you're stuck with adapting the code and have a specific question, we can help.

Do you want to do this by code or manually.

If you want to do it manually simply copy every thing by CTRL + C and Open and Excel and new Worksheet and past it there via CTRL + V. Simple.

Thanks

I'm pretty darned sure that people have written articles on this. You might want to search for them as it's unlikely that anyone here will give you what is usually commercial and proprietary code.

Hi all,

I try to send data to my workflow machine state asynchronously.
I have +- 15 states, and I want a listener who catch data at any time.
I try with this : Asynchronous and Event-Based Activities
But it doesn't work (I can catch data, but just one time Confused | :confused:

)

Do you have any ideas to do that?

Thank you for your help!

Yes, we are Legion Thumbs Up | :thumbsup:

I fail to see how that's relevant to your question though. You requested an example on solitaire, and there's an article on site that shows how to create one. It was either that, or a link to MSDN on drag & drop. Seemed that the article was more appropriate.

Did I misunderstand your query?
