Use String.IndexOf

http://msdn.microsoft.com/en-us/library/system.string.indexof.aspx

You can use the IndexOf method on a string, and you can also use the VB InStr function if you wish, although I would suggest sticking to .NET specific functions.

I would also suggest that you take a look at the documentation of the String methods which will help you know what functionality is available in the framework when working with strings. You can also take a look at the documentation for VB-specific string functions.

no indexof is
