Property Value

true if the handle is closed; otherwise, false.

The IsClosed method returns a value indicating whether the SafeHandle object's handle is no longer associated with a native resource. This differs from the definition of the IsInvalid property, which computes whether a given handle is always considered invalid. The IsClosed method returns a true value in the following cases:

  • The SetHandleAsInvalid method was called.

  • The Dispose method or Close method was called and there are no references to the SafeHandle object on other threads.
