Examples
The following example shows how to create a WebRequest instance by calling the Create method on the WebRequest class.
WebRequest^ myRequest = WebRequest::Create( "http://www.contoso.com" );
WebRequest myRequest = WebRequest.Create("http://www.contoso.com");
Dim myRequest As WebRequest = WebRequest.Create("http://www.contoso.com")
Remarks
Use the Create method to initialize new WebRequest instances. Do not use the constructor.
