The following example demonstrates an error that causes the ObjectDisposedException exception to be thrown.

Imports System.IO

Public Class Example

   Public Shared Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim ms As New MemoryStream(16)
      Catch e As ObjectDisposedException
         outputBlock.Text += String.Format("Caught: {0}", e.Message) & vbCrLf
      End Try
   End Sub 'Main
End Class 'ObjectDisposedExceptionTest
using System;
using System.IO;

public class Example
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
      MemoryStream ms = new MemoryStream(16);
      catch (ObjectDisposedException e)
         outputBlock.Text += String.Format("Caught: {0}", e.Message) + "\n";

This code produces the following output:

  Cannot access a closed Stream.
