How to replace non-numeric characters in a text string?

In vb.net, I am importing a phone number text field, and I need to output it as a field of all numerics.  Quite often the input will have hyphens that I need to eliminate, so I've been handling that with:
StrJ=StrJ.Replace("-", "")    which works fine.

But now I find that all kinds of other stuff is coming in, such as parentheses, asterisks, extra spaces, and even letters.  Is there an easy way to eliminate any and all characters that are not numeric?  I need to have a clean output that is nothing but the digits in the phone number.

OK, I understand the concept (not isnumeric), but I need more detail on how to implement it (I'm new at vb).

Say I've got this string coming in that I'm calling StrJ, and it contains: 1-731-8227 (Joe)

And I want to end up with: 17318227

It's fine with me if it ends up still in StrJ, or in a different string name if that's easier.

With that in mind, how would I implement your concept above?  If possible, please give me a detailed example...
