Release resources in .Net C#

Question

I\'m new to C# and .NET, ,and have been reading around about it.

I need to know why and when do I need to release resources? Doesn\'t the garbage collector take care of

Answer 1

Resources are of two kinds - managed, and unmanaged. Managed resources will be cleaned up by the garbage collector if you let it - that is, if you release any reference to the object. However, the garbage collection does not know how to release unmanaged resources that a managed object holds - file handles, and other OS resources for example.

IDisposable is best practice when there's a managed resource you want released promptly (like a database connection), and vital when there are unmanaged resources which you need to have released. The typical pattern:

public void Dispose()
protected void Dispose(bool disposing)

Lets you ensure that unmanaged resources are released whether by the Dispose method or by object finalisation.
