If you used to be a VB developer, but for some reason are writing C# now, you probably miss a couple of functions. I remember being a little frustrated when I did the conversion from VB.NET to C#. It was March 2005 and I made the shift on the .NET 2.0 beta platform. I couldn’t understand why C# didn’t have some of the simplest functions like IsNumeric() and IsDate(). Also Left(), Right() and Middle() were missing. You could add a reference to the Microsoft.VisualBasic namespace, but that seemed like overkill for a few simple methods.
