sir, just get the index of "@" and split the first 2 char by substring and change the remaining text length by number of stars or asterisk.

Solution 2

Try:

C#

string input = "facebook@gmail.com";
int index = input.IndexOf('@');
string output = input;
if (index > 3)
    {
    output = input.Substring(0, 2) + new string('*', index - 2) + input.Substring(index);
    }
