How to write data to HttpWebRequest using stream / stream writer

Question

Hi All, I am using HttpWebRequest in my code. My problem is that I want to post some data using HttpWebRequest, I have also written some code for this, see the part of code below, HWReq.ContentLength = Buffer.Length; Stream PostData = HWReq.GetRequestStream(); // HWReq is the HttpWebRequest object. PostData.Write(Buffer, 0, Buffer.Length); // Buffer is the ByteArray. PostData.Close(); during execution, I am not receiving any error but there is no effect of the above code. I have also tried the following code, but it is also not working. HWReq.ContentLength = cData.Length; StreamWriter SW = new StreamWriter(HWReq.GetRequestStream()); // HWReq is the HttpWebRequest object. SW.Write(cData, 0, cData.Length); // cData is the charector Array SW.Close(); I am facing this proble since many days and still I have no solution, Can any body help me please? Any hint will also fine. Thanks, Kiran Suthar.
