Question

Is there a way to check to see if a string contains any numeric digits in it without using regex? I was thinking of just splitting it into an array and running a search on that, but something tells me there is an easier way:

//pseudocode
string aString = "The number 4"

If (aString contains a number) Then enter validation loop
Else return to main

//output
"The string contains a number. Are you sure you want to continue?"

You could use String.IndexOfAny as:

bool isNumeric = mystring.IndexOfAny("0123456789".ToCharArray()) > -1;
