El siguiente ejemplo muestra el uso de HttpVersion.

// Create a 'HttpWebRequest' object.
HttpWebRequest^ myHttpWebRequest = (HttpWebRequest^)( WebRequest::Create( "http://www.microsoft.com" ) );
Console::WriteLine( "\nThe 'ProtocolVersion' of the protocol before assignment is : {0}", myHttpWebRequest->ProtocolVersion );
// Assign Version10 to ProtocolVersion.
myHttpWebRequest->ProtocolVersion = HttpVersion::Version10;
// Assign the response Object* of 'HttpWebRequest' to a 'HttpWebResponse' variable.
HttpWebResponse^ myHttpWebResponse = (HttpWebResponse^)( myHttpWebRequest->GetResponse() );
Console::WriteLine( "\nThe 'ProtocolVersion' of the protocol after  assignment is : {0}", myHttpWebRequest->ProtocolVersion );
Console::WriteLine( "\nThe 'ProtocolVersion' of the response Object* is : {0}", myHttpWebResponse->ProtocolVersion );

// Create a 'HttpWebRequest' object.
HttpWebRequest myHttpWebRequest=(HttpWebRequest)WebRequest.Create("http://www.microsoft.com");
Console.WriteLine("\nThe 'ProtocolVersion' of the protocol before assignment is :{0}",myHttpWebRequest.ProtocolVersion);
// Assign Version10 to ProtocolVersion.
myHttpWebRequest.ProtocolVersion=HttpVersion.Version10;
// Assign the response object of 'HttpWebRequest' to a 'HttpWebResponse' variable.
HttpWebResponse myHttpWebResponse=(HttpWebResponse)myHttpWebRequest.GetResponse();
Console.WriteLine("\nThe 'ProtocolVersion' of the protocol after  assignment is :{0}",myHttpWebRequest.ProtocolVersion);
Console.WriteLine("\nThe 'ProtocolVersion' of the response object is :{0}",myHttpWebResponse.ProtocolVersion);

' Create a 'HttpWebRequest' object.
Dim myHttpWebRequest As HttpWebRequest = CType(WebRequest.Create("http://www.microsoft.com"), HttpWebRequest)
Console.WriteLine(ControlChars.Cr + "The 'ProtocolVersion' of the protocol before assignment is :{0}", myHttpWebRequest.ProtocolVersion)
' Assign Version10 to ProtocolVersion.
myHttpWebRequest.ProtocolVersion = HttpVersion.Version10
' The response object of 'HttpWebRequest' is assigned to a 'HttpWebResponse' variable.
Dim myHttpWebResponse As HttpWebResponse = CType(myHttpWebRequest.GetResponse(), HttpWebResponse)
Console.WriteLine(ControlChars.Cr + "The 'ProtocolVersion' of the protocol after  assignment is :{0}", myHttpWebRequest.ProtocolVersion)
Console.WriteLine(ControlChars.Cr + "The 'ProtocolVersion' of the response object is :{0}", myHttpWebResponse.ProtocolVersion)
