And?
I repeat:

We can't see your screen, access your HDD, or read your mind - we only get exactly what you tell us!

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace DataGridJsonTest
{   
    class DataFiles

        public file[] files { get; set; }
    }

    public class file
    {
        public string name { get; set; }

}

            WebClient client = new WebClient();
            var json = client.DownloadString("http://192.168.1.182/api/files/local?apikey=A6C6603BB2F743D6B084D7F52E568011");

            List<DataFiles> DataFiles = JsonConvert.DeserializeObject<List<DataFiles>>(json); 

            gvData.DataSource = DataFiles;
        }
    }
}

i will all names in a GridView

OriginalGriff23-Oct-15 23:42

23-Oct-15 23:42

And?

What did it do that you didn't expect, or not do that you did?

What happened? What was displayed, what wasn't?
What was in json after the download? What did the debugger show?
What went in the List?

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

i get this exception:

Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[DataGridJsonTest.DataFiles]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.

To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List<t>) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object.

Path 'files', line 2, position 11.

this is the json download:

At the moment, your JSON data doesn't look anything like the structure you are trying to deserialize it into - so you get an error.
Have a look at this: http://stackoverflow.com/questions/11126242/using-jsonconvert-deserializeobject-to-deserialize-json-to-a-c-sharp-poco-class[^] - it's exactly the same problem, and it's a "pretty" way to solve it.

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

I am using avro calling Java from c#. Error message "The underlying connection was closed: The connection was closed unexpectedly." C# side upon Java call to flush or close

C# side fires off the request from here:

            httpRequest = HttpWebRequest.Create(targetUrl) as HttpWebRequest;
            httpRequest.Method = "POST";
            httpRequest.Accept = "avro/binary";
            httpRequest.ContentType = "avro/binary";
            httpRequest.KeepAlive = false;

<pre>
        SpecificDatumWriter<SomeRequest> someRequestWriter = new SpecificDatumWriter<SomeRequest>(SomeRequest._SCHEMA);
        ...
        using (var requestStream = httpRequest.GetRequestStream())
        {
            someRequestWriter.Write(someRequest, new Avro.IO.BinaryEncoder(requestStream));

            // C# blows up here!!!
            using (var responseStream = httpRequest.GetResponse().GetResponseStream())
            {
                SpecificDatumReader<SomeResponse> someResponseReader = new SpecificDatumReader<SomeResponse>(null, SomeResponse._SCHEMA);
                someResponse = someResponseReader.Read(null, new Avro.IO.BinaryDecoder(responseStream));
                ...
            }
        }</pre>

And java side handles the request, and respond like this:

HttpExchange.getResponseBody().flush() or HttpExchange.close()

public void handle(HttpExchange t) throws IOException {
        final DecoderFactory decoderFactory = DecoderFactory.get();
        final Decoder decoder = decoderFactory.binaryDecoder(t.getRequestBody(), null);
        SpecificDatumReader<demo.avro.SomeRequest> someRequestReader = new org.apache.avro.specific.SpecificDatumReader<demo.avro.SomeRequest>(GenericRequest.class) ;
        SomeRequest req = someRequestReader.read(null, decoder);
        ...

<pre>
    SomeResponse someResponse = new SomeResponse();
    someResponse.setUserId("john.doe");
    someResponse.setResultItemList(results);

    DatumWriter<SomeResponse> someRequestWriter = new org.apache.avro.specific.SpecificDatumWriter<SomeResponse>(SomeResponse.class);

    final EncoderFactory encoderFactory = EncoderFactory.get();
    final Encoder encoder = encoderFactory.binaryEncoder(t.getResponseBody(), null);

    someRequestWriter.write(genericResponse, encoder);

    **// HERE!!! flush or close will blow up C# side**
    // encoder.flush();
    // t.getResponseBody().flush();
    // t.close();

    return;
}</pre>

I don't know how else to "Flush" my response from Java side back to C#. (If I don't flush or close, C# side will still eventually blow up on timeout) Any suggestion?

Using NLog in many classes

Member 1206160022-Oct-15 7:08

22-Oct-15 7:08

I am learning to use NLog. My situation is I want to use it inside DLL probably wrap it inside a log class. Basically my goals are:

1) I want this configuration to occur only ONCE:

var config = new LoggingConfiguration();

var fileTarget = new FileTarget();
config.AddTarget("file", fileTarget);

 // Step 3. Set target properties
 fileTarget.Layout = @"${date:format=HH\:mm\:ss} - ${message}";
 fileTarget.FileName = "c:/myFolder/" + "${date:format=yyyy-MM-dd}.log";

 var rule2 = new LoggingRule("*", LogLevel.Debug, fileTarget);
 config.LoggingRules.Add(rule2);

 // Step 5. Activate the configuration
 LogManager.Configuration = config;

 // Example usage
 _logger = LogManager.GetLogger("Example");

Also if it will be relevant I want to be able to specify say log file dir as a parameter.

2) Any other class should be able to call a method like LogWrapper.Log("message"), which should log messages using my configured NLog object - I know which method of NLog writes the entry to log file, that is not a problem, say it is called _logger.write.

How can I achieve this in a (thread) safe way? I have been struggling with this for a while already and would appreciate much help!

I would prefer to go with my solution plus I am not that experienced with .NET so didn't really get what you mean, but anyway like I said, I would prefer help on my question.

NLog is thread-safe:

[^]

Check the first reply :
http://stackoverflow.com/questions/5706119/how-thread-safe-is-nlog[^]

This was 2011, so I'm guessing nlog has fixed that for sure.

Best,
John

Yes but I want that configuration code I listed in item 1 to be run only once.

And then everytime someone refers to my logger they should use instance which comes from that configuration.

Assuming Listing 1 compiles, just wrap that into a singleton (static function).

Can you show me example? I want to pass log dir as parameter too. Yes it compiles

but also who and how would actual logging be called (item 2)
