{ // limits scope of myRes

    MyResource myRes= new MyResource();

    try

    {

        myRes.DoSomething();

    }

    finally

    {

        // Check for a null resource.

        if (myRes!= null)

            // Call the object's Dispose method.

            ((IDisposable)myRes).Dispose();

    }

}

We can write above code like this

using (MyResource myRes = new MyResource())

{

    myRes.DoSomething();

}

The Using Keyword takes care of freeing the resources automatically associated with the block.
