ASP.NET MVC4 custom formatting method for Model

Question

 <div>
Email: 
<a id="email href="mailto:@Model.Contact.Email">@Model.Contact.Email.ToStringMyCustomFormatted</a>
</div>

I want to create custom method for formatting and apply it like this. (in the same way we can apply ToString() method to this.) I don't want to use JavaScript to do any formatting by using Document.Ready(). In short I want to extend ToString method something like ToStringMyCustomFormatted, by which I can apply my own rules to string output. I am not even sure if something like can be done. Please Enlighten !

You could use a simple C# extension method (or directly on your Contact model):

public static class YourContactModelExtensions {
    public static string ToStringMyCustomFormat(this YourContactModel m) {
        // TODO
    }
}

or if you wanted it to apply to all strings:

public static class StringExtensions {
    public static string ToMyCustomFormat(this string s) {
        // TODO
    }
}

or a Razor helper function on your Razor page:

@helper ToStringMyCustomFormat(YourContactModel m) {
   @* TODO *@
}

or

@helper ToMyCustomFormat(string s) {
   @* TODO *@
}

Thanks ... ! I am following this link : How to: Implement and Call a Custom Extension Method (C# Programming Guide)

Just one problem: the extension should be to String not to Contact, since the method is being called off of the Email property, not the instance directly.
