HttpRequest and POST

Question

I keep getting one of the following error messages :

\"The remote server returned an error: (400) Bad Request.\"  
               OR
\"System.Net.ProtocolVio         


        

Answer 1

    req.ContentLength = bld.Length;
    StreamWriter writer = new StreamWriter(req.GetRequestStream());
    var encodedData = Encoding.ASCII.GetBytes(bld.ToString());
    writer.Write(encodedData);

You are not writing what you say you are going to be writing- you write the ASCII encoded bytes not your original byte array - the ContentLength has to match the number of bytes you write. Instead do:

    var encodedData = Encoding.ASCII.GetBytes(bld.ToString());
    req.ContentLength = encodedData.Length;
