SafeHandle.Close Method

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

Marks the handle for releasing and freeing resources.

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

public void Close ()
public void Close ()
public function Close ()

Calling the Close or Dispose method allows the resources to be freed. This might not happen immediately if other threads are using the same safe handle object, but will happen as soon as that is no longer the case. Although most classes that use the SafeHandle class do not need to provide a finalizer, this is sometimes necessary (for example, to flush out file buffers or to write some data back into memory). In this case, the class can provide a finalizer that is guaranteed to run before the SafeHandle critical finalizer runs.

Call the Close or Dispose method when you are finished using the SafeHandle object.

NoteNote

Always call Close or Dispose before you release your last reference to the SafeHandle object. Otherwise, the resources it is using will not be freed until the garbage collector calls the SafeHandle object's Finalize method.
