check ALL arguments in c# that they can be numeric : <p>I am writing a small console application in C# and it requires two numeric parameters/arguments to be passed to it.  I am checking for no params, more than 2 params, if two params.  I am also converting those params if 2 returned to numeric for calculations I'm doing.  One thing I'm not doing is verifying what's being passed is a number so assume program will crap out if I pass a letter.  Is there a look routing I can just run to verify the params passed are in deed able to be numbers?  I can handle the kick out from there but curious how you check if an argument CAN be a number or not.</p>

<p>Thanks.</p>
