Verification of mobile phone numbers in ASP.

in ASP. NET MVC, you can use the RegularExpression feature to verify your phone number.

     Public class Customer
    {
        [Required (errormessage = " required ")]
        [Display (Name = " phone number ")]
        [RegularExpression (@ "^1[3458][0-9]{9}$", errormessage = " cell phone number is not formatted correctly ")]
         Public string Get set; }
    }

In the HomeController:

     Public class Homecontroller:controller
    {
         Public ActionResult Index ()
        {
            return View (new Customer ());
        }
        [HttpPost]
         Public ActionResult Index (Customer customer)
        {
            if (Modelstate.isvalid)
            {
                return Content ("OK");
            }
            Else
            {
                return View (customer);
            }
        }
    }    

In views/shared/_layout.cshtml, you must refer to the relevant JS for asynchronous validation.

@Scripts. Render ("~/bundles/jquery")
@Scripts. Render ("~/bundles/jqueryval")    

In the home/index.cshtml:

@model MvcApplication1.Models.Customer
@{
    Viewbag.title = "Index";
    Layout = "~/views/shared/_layout.cshtml";
}
@using (Html.BeginForm ("Index", "Home", FormMethod.Post))
{
    @Html. labelfor (M = m.phonenumber)
    @Html. textboxfor (M = m.phonenumber)
    @Html. validationmessagefor (M = m.phonenumber)
    <br/>
    <input type= "submitvalue=" commit "/>
}
