Question

private void test()
{
    string tst = null;
    try
    {
        tst = "abc";     
    }
    catch (Exception)
    {
        throw;
    }
    finally
    {
        tst = null;           
    }
}

My query is – Is it meaningful to type tst = null; in the finally block as the string class doesn’t have the disposable method ?

Answer 1

Even if string implemented IDisposable, setting a variable to null wouldn’t call the Dispose method. It’s utterly pointless, as is the catch block with the throw.

If you see code like this in a codebase you’re maintaining, rip it out and have a quiet word with whoever put it in there in the first place.
