Question

I am trying to call a webservice. I am getting 500 internal error. webservice is running .I uses the following code

I am getting the error at this point:

WebResponse response = request.GetResponse();

Code:

    string requestxml = @"C\request.xml";

    XmlDocument xmlDoc = new XmlDocument();
    xmlDoc.Load(requestxml);
    StringWriter sw = new StringWriter();
    XmlTextWriter tx = new XmlTextWriter(sw);
    xmlDoc.WriteTo(tx);

    byte[] bytes = Encoding.UTF8.GetBytes(sw.ToString());



    WebRequest request = WebRequest.Create("http://localhost:3993/test.asmx");

    request.Method = "POST";


    byte[] byteArray = Encoding.UTF8.GetBytes(sw.ToString());

     request.ContentType = "application/xml";


    request.ContentLength = byteArray.Length;

    Stream dataStream = request.GetRequestStream();

    dataStream.Write(byteArray, 0, byteArray.Length);

    dataStream.Close();

    WebResponse response = request.GetResponse();

We need to know the actual exception, and where it's actually happening within the code. — Andrew Barber
You should run the local iis for this , i suggest you to turn on two Visual Studio on project is the client the other one is server, after you turn the server [CTRL+F5] you take the address of the server url like you have done.<br/> After that you go to the client and make the request, it should work. — IamStalker
@ Andrew when i call from powershell,the webservice is running perfectly responding.when i call from c#,it is showing this error — user386258
Show us the PowerShell code. It's doing something different. — Roger Lipscombe

The 500 response indicates there is a problem in the webservice. You need to debug the webservice, not the call to the service. I would first verify that your method is being called, and then work on from there.

If your webservice is not being called, then you need to verify the XML that is being sent, and the URL for the webservice.
