How to Range validation integer ASP.NET MVC 3

Question

I'm using validations as below.

[Required(ErrorMessage = "Please provide 10 digit mobile number without spaces and without country code (+91)")]
[Integer(ErrorMessage = "Please provide 10 digit mobile number without spaces and without country code (+91)")]
[Range(1000000000, 9999999999, ErrorMessage = "10 digit mobile number only without spaces and without country code (+91)")]
[Display(Name = "Mobile Number")]
public int MobileNo { get; set; }

It is always failing the validations saying The value '9999999998' is invalid.. Am I doing something wrong?

Try this:

[RegularExpression("^[0-9]{10}$", ErrorMessage = "Invalid Mobile No")]

The maximum value that an Int32 type could store is 2,147,483,648. You are overflowing. Why are you using an integer type to represent a phone number? String seems more adapted.

I thought specifying range would be easy on numeric that's why. No special reason. I mean I thought if I take string then it will have to do two checks i.e. length and numerics.

You could use a regular expression.

I'm simply not able to understand RegEx yet. :(. @Vinod's answer will help for now.

The Max Value an Integer(Int32) can hold is 2,147,483,647. So you should better replace Int with Long or String.
