Hello all.  I need to take a value such as SSN and replace all the values of the string other than the last 4 numbers.  For example, 111111111 to *****1111.  Then I need to also keep the actual value though for an update.  Any ideas?

Learned one that is correct I want to change the value of the SSN where it shows just the last 4 digits but then I do need to still have the actual value itself to store on an update.  The page is SSL but they want this.

right now it comes back in free text via a web service call.  I need to take that value and mask it and then display it.

Do you want to do something like this?

            string ssn = "123-45-6789";

            this.txtSSN.Text = new string('*', ssn.Length - 4) + ssn.Substring(ssn.Length - 4);
