Question

This is a JS regular expression to have at-least one alphabet, one number & one special character in any string.

var pattern = /^(?=.*?[a-z])(?=.*?\d)(?=.*?[!@#$%\^&*\(\)\-_+=;:'"\/\[\]{},.<>|`])/i
pattern.test("Test123!@#")

How do we write same regex in C#?

Answer 1

This should do:

if (Regex.IsMatch("Test123!@#",
              @"^(?=.*?[a-z])(?=.*?\d)(?=.*?[!@#$%\^&*\(\)\-_+=;:'""\/\[\]{},.<>|`])", 
              RegexOptions.IgnoreCase))
{
    // do something
}
