WebRequest.GetRequestStream Method
Assembly: System (in system.dll)
The GetRequestStream method initiates a request to send data to the Internet resource and returns a Stream instance for sending data to the Internet resource.
The GetRequestStream method provides synchronous access to the Stream. For asynchronous access, use the BeginGetRequestStream and EndGetRequestStream methods.

| The WebRequest class is an abstract class. The actual behavior of WebRequest instances at run time is determined by the descendant class returned by the System.Net.WebRequest.Create method. For more information about default values and exceptions, see the documentation for the descendant classes, such as HttpWebRequest and FileWebRequest. |
The following example uses the GetRequestStream method to obtain a stream and then writes data that stream.
// Set the 'ContentType' property of the WebRequest. myWebRequest.ContentType="application/x-www-form-urlencoded"; // Set the 'ContentLength' property of the WebRequest. myWebRequest.ContentLength=byteArray.Length; Stream newStream=myWebRequest.GetRequestStream(); newStream.Write(byteArray,0,byteArray.Length); // Close the Stream object. newStream.Close(); // Assign the response object of 'WebRequest' to a 'WebResponse' variable. WebResponse myWebResponse=myWebRequest.GetResponse();
// Set the 'ContentType' property of the WebRequest.
myWebRequest.set_ContentType("application/x-www-form-urlencoded");
// Set the 'ContentLength' property of the WebRequest.
myWebRequest.set_ContentLength(byteArray.get_Length());
Stream newStream = myWebRequest.GetRequestStream();
newStream.Write(byteArray, 0, byteArray.get_Length());
// Close the Stream object.
newStream.Close();
// Assign the response object of 'WebRequest' to a 'WebResponse'
// variable.
WebResponse myWebResponse = myWebRequest.GetResponse();
