ObjectDisposedException Class
.NET Framework 2.0
The exception that is thrown when an operation is performed on a disposed object.
Namespace: System
Assembly: mscorlib (in mscorlib.dll)
Assembly: mscorlib (in mscorlib.dll)
[SerializableAttribute] [ComVisibleAttribute(true)] public ref class ObjectDisposedException : public InvalidOperationException
/** @attribute SerializableAttribute() */ /** @attribute ComVisibleAttribute(true) */ public class ObjectDisposedException extends InvalidOperationException
SerializableAttribute ComVisibleAttribute(true) public class ObjectDisposedException extends InvalidOperationException
The following example demonstrates an error that causes the ObjectDisposedException exception to be thrown.
using namespace System; using namespace System::IO; int main() { MemoryStream^ ms = gcnew MemoryStream( 16 ); ms->Close(); try { ms->ReadByte(); } catch ( ObjectDisposedException^ e ) { Console::WriteLine( "Caught: {0}", e->Message ); } }
import System.*;
import System.IO.*;
public class ObjectDisposedExceptionTest
{
public static void main(String[] args)
{
MemoryStream ms = new MemoryStream(16);
ms.Close();
try {
ms.ReadByte();
}
catch (ObjectDisposedException e) {
Console.WriteLine("Caught: {0}", e.get_Message());
}
} //main
} //ObjectDisposedExceptionTest
This code produces the following output:
