To register as a user example

First step: Add a View model

public class Viewregmodels {     [Display (name = "user name")]     [Required (allowemptystrings = false, ErrorMessage = ") User name cannot be empty ")] public     string UserName {get; set;}     [Display (Name = "password"), DataType (Datatype.password)]     [Required (allowemptystrings = false, errormessage = "Password cannot be empty")]     public string Password {get; set;}     [Display (Name = "Confirm password"), DataType (Datatype.password)]     [Required (allowemptystrings = false, errormessage = "Confirm password cannot be empty")]     [Compare ("Password", errormessage = "Password and Confirm password are not the same")]     public string Confrimpassword {get; set;}     public string ReturnUrl {get; set;}}

Step Two: Add a controller

2. Add HttpGet
   

   [HttpGet] public iactionresult Reg () {     return View ();}

4. Add HttpPost
   

   [Httppost]public async task<iactionresult> Reg (viewregmodels view) {    if (!this. Isformvalid ()) {        Modelstate.addmodelerror (string. Empty, this. Forminvalidreason ());        Return await Task.fromresult (view);    }    var result = resolve<iuserservice> (). Reg (view. UserName, view. Password);    if (!result. Succeeded) {        Modelstate.addmodelerror (string. Empty, result. ToString ());        Return await Task.fromresult (view);    }    String url = resolve<iautoconfigservice> (). Getdata<userloginregconfig> (). Afterregurl;    if (URL. IsNullOrEmpty ()) {        URL = "/index";    }    return Redirect (URL);}

6. Precautions
   
   • You must use this. Isformvalid to verify all the fields
   • Use this. Forminvalidreason Display specific error validation information for a field
   • Modelstate.addmodelerror to display the error messages submitted by the form
   • Use asynchronous commits whenever possible

Step Three: Add views view file

@model zkcloud.core.user.viewmodels.viewregmodels<div class= "Userlogin row" > <form method= "POST" class= " Form-horizontal form-row-seperated "asp-controller=" User "asp-action=" Reg "> <div class=" Form-group-error "&G            T <div class= "Col-md-offset-2 col-md-10" > <div asp-validation-summary= "All" class= "Text-danger" >& lt;/div> </div> </div> <div class= "Form-group" > <label                Asp-for= "UserName" class= "col-md-2 control-label" ></label> <div class= "col-md-10" > <input asp-for= "UserName" class= "Form-control"/> <span asp-validation-for= "UserName" Class= "Tex T-danger "></span> </div> </div> <div class=" Form-group "> &L                T;label asp-for= "Password" class= "col-md-2 control-label" ></label> <div class= "col-md-10" > <inPut asp-for= "Password" class= "Form-control"/> <span asp-validation-for= "Password" class= "Text-danger "></span> </div> </div> <div class=" Form-group "> <label                Asp-for= "Confrimpassword" class= "col-md-2 control-label" ></label> <div class= "col-md-10" > <input asp-for= "Confrimpassword" class= "Form-control"/> <span asp-validation-for= "Confri Mpassword "class=" Text-danger "></span> </div> </div> <div class=" Form-gro Up "> <div class=" col-md-offset-2 col-md-10 "> <button class=" btn Green Btn-big "> members Registration </button> </div> </div> </form></div>

Precautions:

• • Use <div asp-validation-summary= "All" class= "Text-danger" ></div> to display all error verification information
  • So the field must be added validation <span asp-validation-for= "Confrimpassword" class= "Text-danger" ></span>
  • In order to reduce unnecessary workload, and communication costs. HTML styles that do not allow pure soundtracks
  • All background personnel must have complete control of the HTML structure
