Validation for EmailAdress gets triggered for optional field

Question

I have this email validation attribute

[EmailAddress]
[StringLength(50, ErrorMessage = "Email is too long!")]
public string Email { get; set; }

And it works fine, but the problem is when I type the email, and then erase it, the form still asks me to insert correct email even though the field is not required.

I was not the one who marked it. I just gave you up arrow if that soothes your soul. I will read more into regex, thanks! – Šarūnas Kaulakis Apr 03 '20 at 14:19

Thank you kind Sir, you made it work and my headache is relieved. Have a great day. – Šarūnas Kaulakis Apr 03 '20 at 14:50
Although it solved your problem, it should be another solution without using regex.. – Selim Yildiz Apr 03 '20 at 15:01
@ŠarūnasKaulakis you are welcome and hope you learn something which is very much required with different kinds of string validation. – Jigar Sangoi Apr 03 '20 at 15:26
