There is no equivalent of IsNumeric in C# but see something very closely...
IsNumeric Function is in Microsoft.VisualBasic namespace. So you can
reference Microsoft.VisualBasic.Runtime assembly in your project and use all
Visual Basic Functions in C# Cheers

what will be corresponding keyword against it

1) Launch your Internet browser (IE, FireFox, Mozilla, Netscape etc)

2) Navigate to http://www.google.com

3) Enter the text below in the box:

4) Hit the button

Actually, that's not true. IsNumeric is a managed function, and you can
access it on the Interaction class in the Microsoft.VisualBasic namespace in
Microsoft.VisualBasic.dll.

Hi Vikas,


Thank you for posting.

Besides above solutions, here's a kb article:

How to implement Visual Basic .NET IsNumeric functionality by using Visual
C# .NET or Visual C# 2005

A problem with that KB article is that passing null to the method causes an
exception while the VB IsNumeric handles the VB equivalent Nothing.
See the following link for a more accurate C# equivalent:

Thanks David.

I agree with you on this. While the code in the kb produces correct result
regarding null value, it indeed incurs an unnecessary exception in
Double.TryParse() call.

Anyway, the easiest way is to simply use the version in
Microsoft.VisualBasic.dll.
