In visual Basic Script there is a function called isNumeric().  I need
to know how to achive that same functionality in c#?

elraitan-ga,

The short answer to your question is that there is no function in C#
which is  equivilant to the isnumeric() function in VB.

However, you can usein C#, a VB6 compatibility library to achieve the
same thing.

Here is more information on exactly how to do this, from VBCity.com

Google search strategy: 

Keywords, "C# isnumeric() function"

://www.google.com/search?hl=en&ie=ISO-8859-1&q=C%23+isnumeric%28%29+function

Good luck in continuing your inquiries!

This was an experiment to see what you would produce.  There were
about three other answers as well but I too like this one the best. 
Good job!

elraitan,
   The .NET BCL provides static methods such as Char.IsDigit and
Char.IsNumber.  Please check the MSDN online documentation listed
below for their implementation:

<a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemCharClassIsDigitTopic.asp"
target="_blank">Char.IsDigit Method</a>

<a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfSystemCharClassIsDigitTopic.asp"
target="_blank">Char.IsNumber Method</a>

Hope this helps,
