checking for numbers in C#.net

[Guest]

Hello,
Is there a command in C# which will allow me to check whether or not a
variable is a number? Something similar to the VB isNumeric command?

Thanks,
Ben

Check out the Int32.TryParse method:

What do you mean by that?
You have an object that you want to test if it is of type Int32, double, etc
numeric types or you have a string and you want to check whether it
represent a correct number?


For the first case what comes to my mind is to write a method that will
first call

obj.GetType.IsPrimitive

If the type of the object is one of the promitive you just need to filter
out the two types that are not numeric - Char and Boolean

What I mean is I want to check a variable and determine whether that
variable is a string or an Int32. The Int32.TryParse method that Chris
posted does exactly what I needed.

Thanks,

If you're using .NET 2.0, you can use the int.TryParse method
