Question

I’m writing an extension method called ToPhoneFormat that formats a string of digits to phone numbers.

Is it possible to add a parameter to the method that would enable me to call it like this: MyPhoneString.ToPhoneFormat(international code)

That way, I could write MyPhoneString.ToPhoneFormat(1); to format a US phone number and MyPhoneString.ToPhoneFormat(33) to format a French phone number.

I already wrote the method that does the formatting but I’m wondering how to build the constructor so that it works with a parameter when I’m calling it.

Thanks.

nice and easy 🙂

I’m assuming your method signature for ToPhoneFormat looks something like:

public static string ToPhoneFormat(this string sourceString) 
{
    /* Your code here */ 
}

if so, the all you need to do is add a parameter after the this parameter, so it becomes:

public static string ToPhoneFormat(this string sourceString, int countryCode)
{
    /* Your code here */
}
