Example
[Visual Basic, C#, C++] The following example demonstrates an error that causes the ObjectDisposedException exception to be thrown.
[Visual Basic] Imports System Imports System.IO Public Class ObjectDisposedExceptionTest Public Shared Sub Main() Dim ms As New MemoryStream(16) ms.Close() Try ms.ReadByte() Catch e As ObjectDisposedException Console.WriteLine("Caught: {0}", e.Message) End Try End Sub 'Main End Class 'ObjectDisposedExceptionTest [C#] using System; using System.IO; public class ObjectDisposedExceptionTest { public static void Main() { MemoryStream ms = new MemoryStream(16); ms.Close(); try { ms.ReadByte(); } catch (ObjectDisposedException e) { Console.WriteLine("Caught: {0}", e.Message); } } } [C++] #using <mscorlib.dll> using namespace System; using namespace System::IO; int main() { MemoryStream* ms = new MemoryStream(16); ms->Close(); try { ms->ReadByte(); } catch (ObjectDisposedException* e) { Console::WriteLine(S"Caught: {0}", e->Message); } }
[Visual Basic, C#, C++] This code produces the following output:
