Email validation function cannot insert inside the cs file

Question

I have a regex email validation function that i have take it from here .But the problem is when i insert it to my cs file then it shows me the errors.( it shows me lots of erors like unexpected / , ] expected,; expected )

Code

function ValidateEmail(email) {
                        var expr = /^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/;
                        return expr.test(email);
                    }

In here i have paste the screenshots also,

I strongly recommend you use the `[EmailAddress]` attribute on your property instead (which will correctly validate the property on both the client and the server) using a correct regular expression — , Jul 26 '15 at 01:35
try `@Html.Raw("/^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$/");` — Khanh TO, Jul 26 '15 at 01:45

It's because you're trying to use @ in JS but it's recognized as a Razor expression - you see that Razor colored it yellow? you need to escape it. e.g. use @@ so Razor would understand you're not writing a Razor expression.

I think you want to use that regex in C# if yes try it like this:

[IdeOne Demo]

string email = "an.email@ahost.com";
string regex = @"^([\w-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([\w-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$";

Regex rgx = new Regex(regex);

Boolean result = rgx.IsMatch(email);
