\ is showing as an unexpected character ? is showing "invalid expression term " – Baktha Aug 09 '18 at 13:18

and also shows "the name 'w' does not exist in the curent content" – Baktha Aug 09 '18 at 13:19

OK thank you so much – Baktha Aug 09 '18 at 13:21

`[\w]+` seems unnecessary. Try making it `\w+` instead. – blhsing Aug 09 '18 at 13:26

let me try this – Baktha Aug 09 '18 at 13:28

still error showing – Baktha Aug 09 '18 at 13:29

Perhaps you're using a language where `@` is interpreted as a special character. Try escaping `@` with `\@`. – blhsing Aug 09 '18 at 13:31

that works fine but remaining place error showing – Baktha Aug 09 '18 at 13:36

What "place error" do you mean? – blhsing Aug 09 '18 at 13:37

please see the image i have attached now – Baktha Aug 09 '18 at 13:44

You need to [escape the `@`](https://stackoverflow.com/a/3700858/884561) because the Razor engine is picking that up as C#/VB.NET code. – Kenneth K. Aug 09 '18 at 13:44

I removed @ symbol and tried. After enter exmple@gmail.com send button is not focusing. It shoud focus when I enter third letter of "com" – Baktha Aug 09 '18 at 13:50

That's a different question. – Kenneth K. Aug 09 '18 at 13:53
-
@Baktha I see your image but it appears that you're still not escaping `@`. Try making it `\@` instead. – blhsing Aug 09 '18 at 13:53

@blhsing Please see the recent image. I have added. But still error – Baktha Aug 09 '18 at 13:58
-

If you use regular expression in a model class then to this way. I use regular expression in my model class as a seen below:
[Required]
[StringLength(50)]
[RegularExpression(@"\b[\w\.-]+@[\w\.-]+\.\w{2,4}\b", ErrorMessage = "example@gmail.com like this pattern")]
public string Email { get; set; }
Follow this method if match your requirment
