Question

I always seem to see if a string (querystring value usually) has a value but first I have to check that it is not nothing first so I end up with 2 if then statements – am I missing somethign here – there has to be a better way to do this:

If Not String.IsNullOrEmpty(myString) Then   If CBool(myString) Then    //code    End If End If 

Answer 1

In VB.Net, And does not short-circuit, but AndAlso does.

(same for Or and OrElse)

So your code should look something like

If Not String.IsNullOrEmpty(myString) AndAlso CBool(myString) Then      .... End If
