What is Finalize and Dispose method in C#?

What is Finalize and Dispose method in C#?

Methods dispose() and finalize() are the methods of C# which are invoked to free the unmanaged resources held by an object. The dispose() method is defined inside the interface IDisposable whereas, the method finalize() is defined inside the class object.

How Dispose method is implemented in C#?

The Dispose Method—Explicit Resource Cleanup

1. public interface IDisposable.
2. {
3. void Dispose();
4. }
5. The following code illustrates how to implement the Dispose method on a class that implements the IDisposable interface:
6. class Test : IDisposable.
7. {
8. private bool isDisposed = false;

What is the difference between Dispose () and Finalize ()?

Finalize is the backstop method, called by the garbage collector when it reclaims an object. Dispose is the “deterministic cleanup” method, called by applications to release valuable native resources (window handles, database connections, etc.)

Why we need to implement Dispose method?

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.

How do you implement a Dispose method?

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.

What is the difference between Dispose and close in C#?

Close() will simply close the connection to the server as defined in the connection string. The Connection can be used/re-opened after this point. Connection. Dispose() will clean up completely, removing all unmanaged resources preventing that Connection from being used again.

What is the difference between Finalize and Dispose in C#?

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.

How Finalize method works in C#?

The Finalize method is used to perform cleanup operations on unmanaged resources held by the current object before the object is destroyed. The method is protected and therefore is accessible only through this class or through a derived class.
