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

hi Pravesh

The reason for the "using" statement is to ensure that the object is always disposed correctly, and it doesn't require explicit code to ensure that this happens.

{ // 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();

}
