The code below always throws a exception when it runs to (JPG and PNG part)bitimg.SetSource(e.Result); As it said, does it mean that I can't use the e.Result because it is disposed?

InvalidOperationException Example The following example demonstrates an error that causes the ObjectDisposedException exception to be thrown. using System; using System.IO; public class ObjectDisposedExceptionTest { http://www1.cs.columbia.edu/~lok/csharp/refdocs/System/types/ObjectDisposedException.html public static void Main() { MemoryStream ms = new MemoryStream(16); ms.Close(); try { ms.ReadByte(); } catch (ObjectDisposedException e) { Console.WriteLine("Caught: {0}", e.Message); } } } This code produces the following output: Caught: Cannot access a closed Stream.
