C# Query from Google

One of the queries that someone entered in to Google and found my site was:
c# test a string to see if it is a number:
I suppose there are a couple of ways that this can be done.

If you know the datatype that you want to convert it to [i.e you know the numeric range] you can use the Convert class.
Convert.ToInt16 (short), Convert.ToInt32 (int), Convert.ToFloat (floats). etc etc

You could also use a regex along the lines of:


both of the above regex’s will check to see if it is a numeric string. (Whole numbers only though).

Anyone who is looking for c# test a string to see if it is a number; I hope you find this usefull.
