Email address validation in C# MVC 4 application: with or without using Regex
asp.net-mvc, asp.net-mvc-4, c#, email-validation, regex
Solution
You need a regular expression for this. Look here. If you are using .net Framework4.5 then you can also use this. As it is built in .net Framework 4.5. Example
[EmailAddress(ErrorMessage = "Invalid Email Address")]
public string Email { get; set; }
Problem
I have an MVC 4 web application and I need to enter and validate some email addresses, without sending an email to the user's email address. Currently I am using basic regex email validation with this pattern: ``` [RegularExpression(@"\A(?:[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?)\Z", ErrorMessage = "Please enter correct email address")] ``` Although this is validating email addresses, it passes 1@1.1 as a valid email address. For the moment I have a validation that requires symbols @ symbols . symbols where the symbols can be numeric/alphabetic and ._- . I need more standard email validation for my MVC 4 application. How do I do that?
