Regex to check if string only contain digits and is 11 characters/digits long?

Question

currently I am using:

if (Regex.IsMatch(searchValue, @"^\d{11}.*") && searchValue.Length == 11)
   {
     // Do something
   }

How can I alter the regex to also check the length and not to use the && operator?

Thanks in advance.

Answer 1

Changing the pattern to

@"^\d{11}$"

Should do it
