When Dispose method is called?
Implement a finalizer to free resources when Dispose is not called. By default, the garbage collector automatically calls an object’s finalizer before reclaiming its memory. However, if the Dispose method has been called, it is typically unnecessary for the garbage collector to call the disposed object’s finalizer.
Which statement describes a Dispose method?
C# provides a special “using” statement to call Dispose method explicitly. using statement gives you a proper way to call the Dispose method on the object. In using statement, we instantiate an object in the statement. At the end of using statement block, it automatically calls the Dispose method.
Why does the Dispose method call GC SuppressFinalize?
The Dispose method performs all object cleanup, so the garbage collector no longer needs to call the objects’ Object.Finalize override. Therefore, the call to the SuppressFinalize method prevents the garbage collector from running the finalizer. If the type has no finalizer, the call to GC.SuppressFinalize has no effect.
Can a disposing object call the Dispose method?
In reading about the Dispose method and the IDisposable interface Microsoft states that the disposing object should only call the Dispose method for its parent. The parent will call it for its parent and so on. To me this seems backwards.
How is the Dispose method used in the garbage collector?
The Dispose method performs all object cleanup, so the garbage collector no longer needs to call the objects’ Object.Finalize override. Therefore, the call to the SuppressFinalize method prevents the garbage collector from running the finalizer.
When do you need a finalizer for the Dispose method?
In these cases, a finalizer is unnecessary. A finalizer is only required if you directly reference unmanaged resources. Here’s the general pattern for implementing the dispose pattern for a base class that uses a safe handle.
