SafeHandle.SetHandleAsInvalid Method

Note: This method is new in the .NET Framework version 2.0.

Marks a handle as no longer used.

Namespace: System.Runtime.InteropServices
Assembly: mscorlib (in mscorlib.dll)

public:
void SetHandleAsInvalid ()
public void SetHandleAsInvalid ()
public function SetHandleAsInvalid ()

Call the SetHandleAsInvalid method only when you know that your handle no longer references a resource. Doing so does not change the value of the handle field; it only marks the handle as closed. The handle might then contain a potentially stale value. The effect of this call is that no attempt is made to free the resources.

As with the SetHandle method, use SetHandleAsInvalid only if you need to support a pre-existing handle.
