When overridden in a descendant class, returns a Stream for writing data to the Internet resource.
Assembly: System (in System.dll)
Any attempt is made to access the method, when the method is not overridden in a descendant class.
The method initiates a request to send data to the Internet resource and returns a Stream instance for sending data to the Internet resource.
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 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 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 Dim newStream As Stream = myWebRequest.GetRequestStream() newStream.Write(byteArray, 0, byteArray.Length) ' Close the Stream object. newStream.Close() ' Assign the response object of 'WebRequest' to a 'WebResponse' variable. Dim myWebResponse As WebResponse = myWebRequest.GetResponse()
