Actually, IsNumeric does two things: converts a string and returns a boolean
true if the resulting expression is recognized as a number. Parse only
converts a string representation of a number to double. I need the boolean
return to validate a text box entry that can't be easily checked with a
validator.

So, check TryParse
MSDN:
The TryParse method is like the Parse method, except this method does not
throw an exception if the conversion fails. If the conversion succeeds, the
return value is true and the result parameter is set to the outcome of the
conversion. If the conversion fails, the return value is false and the
result parameter is set to zero.

I apologize, I read TryParse too fast. You're right, it does what I need.
Thank you,
Stephan.

In VBA, you can use IsNumeric to return True or False if the value being
tested is numeric. Is there an equivalent to this in VB.NET?

Hello,
I have a need to see if a string is numeric or alphabetic. I understand
that Visual Basic has a method called "IsNumeric(string)" but C#
dosen't appear to have one. Any ideas?
Thanks for your help

Hello All:
Does anyone know how someone would check for a numeric value in .NET? In
VB6, we used IsNumeric. What's the .NET equivalent?
BTW, I know that I can harken back to IsNumeric. I'm trying to purge any
trace of VB6 from my code.
TIA,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
