Open controllers, right-click the public ActionResult Register () to add a view, select a strongly typed view, and model class selection Userregister

After the completion of the add to the register.cshtml edit view, delete the automatically generated content, manually enter the code you want to complete the code as follows:  

@model CMS.
 Models.userregister @{viewbag.title = "User Registration";
Layout = "~/views/shared/_layout.cshtml"; } <div class= "banner" >  </div> @using (html.beginform ()) {@Html. ValidationSummary (True) <div class= "form" > <dl> <dt> User registration </dt> <dd> < Div class= "label" > @Html. Labelfor (model => model. UserName):</div> <div class= "Ctrl" > @Html.

Click (function () {$ (" #v Erificationcode "). attr (" src ","/user/verificationcode? ")
 +new Date ());

 }) </script> @section Scripts {@Scripts. Render ("~/bundles/jqueryval")}

Start the code that writes the registration process below. &NBSP
in controllers, in public ActionResult Register () {return View ();} Add a register () Action in the [HttpPost] way below, with the following code: &NBSP

[HttpPost] public actionresult Register (Userregister userreg) {if (session["verificationcode"] = = NULL | | session["Verificationcode"]. ToString () = = "") {Error _e = new Error {Title = "Authentication code does not exist", Details = "When the user registers, the server side of the authentication code is empty, or the authentication code submitted to the server is empty", cause = " ;li> the time you sign up for the registration page has timed out </li><li> you have bypassed the client validation to submit data to the server </li> ", Solution =" return <a href= ' "+
  Url.action ("register", "User") + "' > Registration </a> page, reload after registration"};
  Return redirecttoaction ("Error", "Prompt", _e); else if (session["Verificationcode").
  ToString ()!= userReg.VerificationCode.ToUpper ()) {Modelstate.addmodelerror ("Verificationcode", "X");
  return View ();
  } userrsy = new Userrepository ();
  if (userrsy.exists (Userreg.username)) {modelstate.addmodelerror ("UserName", "User name already exists");
  return View ();
  User _user = Userreg; _user.
  Password = Common.Text.Sha256 (Userreg.password); _user.
  Regtime = System.DateTime.Now; if (Userrsy.add (_user)) {Notice _n = new Notice {Title = "registered Success",Details = "You have successfully registered, the user is:" + _user. UserName + ", please bear in mind your password!
  ", Dwelltime = 5, navigation = Url.action (" Login "," User ")};
  Return redirecttoaction ("Notice", "Prompt", _n); else {Error _e = new Error {Title = "registration Failed", Details = "Unknown error occurred during user registration", cause = "System error", Solution = "<li> return <a href= ' "+ url.action (" register "," User ") +" ' > Registration </a> page, after entering the correct information, re-register </li><li> contact webmaster </
  Li> "};
  Return redirecttoaction ("Error", "Prompt", _e);
 }
 }

OK, run it and see how it works.

Enter the data point registration. OK See the successful registration page

Look, there's a record in the database.

The registration function is complete.
