C# Password Validation

The following function uses a Regular Expression, which you can tweak to just about anything, to check if a password is 8 to 15 in length and contains atleast one digit or symbol.

using System.Text.RegularExpressions;

public bool ValidatePassword(string tPass) { Regex passreg = new Regex("^(?=.*[d$!%^&*()]).{8,15}$”);

Match mRes = passreg.Match(tPass); return mRes.Success; }

Returns true if it matches, false if it doesn’t!
