[c#] Regular expression for 10 digit number without any special characters

What is the regular expression for a 10 digit numeric number (no special characters and no decimal).

\d{10}

I believe that should do it

Use this:

\d{10}

I hope it helps.

Use the following pattern.

^\d{10}$

An example of how to implement it:

public bool ValidateSocialSecNumber(string socialSecNumber)
{
    //Accepts only 10 digits, no more no less. (Like Mike's answer)
    Regex pattern = new Regex(@"(?<!\d)\d{10}(?!\d)");

    if(pattern.isMatch(socialSecNumber))
    {
        //Do something
        return true;
    }
    else
    {
        return false;
    }
}

You could've also done it in another way by e.g. using Match and then wrapping a try-catch block around the pattern matching. However, if a wrong input is given quite often, it's quite expensive to throw an exception. Thus, I prefer the above way, in simple cases at least.
