Dispose Comment Release For Free

It is always recommended to use Dispose method to clean unmanaged resources. You should not implement the Finalize method until it is extremely necessary. At runtime C#, C++ destructors are automatically converted to Finalize method. .

The Dispose Method?Explicit Resource Cleanup The Dispose method generally doesn't free managed memory?typically, it's used for early reclamation of only the unmanaged resources to which a class is holding references. In other words, this method can release the unmanaged resources in a deterministic fashion.

The idiom is to declare which objects you are using and then to create a scope for these objects with curly braces. When the close brace is reached, the Dispose( ) method will be called on the object automatically, as illustrated in Example 4-6.

The Dispose method leaves the Controller instance in an unusable state. After you call Dispose, you must release all references to the Controller instance so that the garbage collector can reclaim the memory that the Controller instance was occupying.

The dispose pattern is used for objects that implement the IDisposable interface, and is common when interacting with file and pipe handles, registry handles, wait handles, or pointers to blocks of unmanaged memory. This is because the garbage collector is unable to reclaim unmanaged objects.

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.

The Dispose() method 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.

The Dispose() method 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.

Because you can't control when (or even if) the GC calls Finalize, you should treat destructors only as a fallback mechanism for releasing unmanaged resources. Instead, the approved way to release unmanaged resources is to make your class inherit from the IDisposable interface and implement the Dispose() method.

The main difference between dispose() and finalize() is that the method dispose() has to be explicitly invoked by the user whereas, the method finalize() is invoked by the garbage collector, just before the object is destroyed.
