C# : What is the difference between dispose and finalize methods in c#

finalizer and dispose both are used for same task like to free unmanaged resources but have some differences see. 

Finalize:

• Finalize used to free unmanaged resources those are not in use like files, database connections in application domain and more, held by an object before that object is destroyed.
• In the Internal process it is called by Garbage Collector and can’t called manual by user code or any service.
• Finalize belongs to System.Object class.
• Implement it when you have unmanaged resources in your code, and make sure that these resources are freed when the Garbage collection happens.

Dispose:

• Dispose is also used to free unmanaged resources those are not in use like files, database connections in Application domain at any time.
• Dispose explicitly it is called by manual user code.
• If we need to dispose method so must implement that class by IDisposable interface.
• It belongs to IDisposable interface.
• Implement this when you are writing a custom class that will be used by other users.
