如何处理Microsoft.aspnetcore.identity的特定错误，在使用密码创建用户时返回？

如何处理特定错误（Microsoft.aspnetcore.inderity.IdentityError）在创建用户期间通过（usermanager＆lt; tuser＆lt; tuser＆gt;）类返回。例如，如果错误是：password tooshort或passwandRequiresnonalphanumeric，我想做一些事情。现在，我获得了有关错误的信息，但是IDK如何处理它们。

我不想做之类的事情，如果（IndentityError ==“错误的名称” {do doys}），我正在寻找更智能的解决方案...我浏览了很多主题，但找不到我的问题的答案，如果您知道一个问题，请重定向我...

编辑：我做了这样的事情：

if (createResult.Errors.Any(x => x.Code == "PasswordTooShort"))
        {
            var errorContent = "kielbaska";
            return RedirectToAction("ShowError", new ErrorFM
            {
                ErrorContent = errorContent
            });
        }

但是我想从括号中替换错误名称，并从可用的列表中替换错误名称结果失败错误，例如类似usrmanager.errordescriber.passwordtooshort（Just and and示例）

How to handle specific error (Microsoft.AspNetCore.Identity.IdentityError) returned during creating user by using (UserManager<TUser>)class. For example, I want to do something if the error is: PasswordTooShort or PasswordRequiresNonAlphanumeric. Now I get information about errors but idk how to handle them.

I don't want to do something like if(IdentityError == "name of error" {do something}), I'm looking for smarter solution... I looked through a lot of topics but cannot find an answer to my question, if you know one, please redirect me...

EDIT: I made something like this:

if (createResult.Errors.Any(x => x.Code == "PasswordTooShort"))
        {
            var errorContent = "kielbaska";
            return RedirectToAction("ShowError", new ErrorFM
            {
                ErrorContent = errorContent
            });
        }

But I want to replace error name from brackets with error name from list of available result failed errors, for example something like thisusrManager.ErrorDescriber.PasswordTooShort(just and example)

因为Usermanager返回身份证，并且具有身份错误
您必须创建一个像MyResult这样的新类，并在其构造函数中获得IdentityResult：

using Microsoft.AspNetCore.Identity;
    public class MyResult
    {
        public bool Succeeded { get; set; }
        public IEnumerable<IdentityError> Errors { get; set; }
        public MyResult(IdentityResult res)
        {
            this.Succeeded = res.Succeeded;
            this.Errors = res.Errors;

            foreach (var error in res.Errors)
            {
                var Error = this.Errors.FirstOrDefault(er => er.Code == error.Code);
                switch (error.Code)
                {
                    case "PasswordRequiresUpper":
                        Error.Description = "YOUR OWN MESSAGE.";

                              break;
                    case "PasswordRequiresLower":
                      Error.Description = "YOUR CUSTOM MESSAGE.";
                             break;
                    // ......
                    default:
                        Error.Description = error.Description;
                        break;
                }
            }

        }
    }

在您的控制器操作或服务功能中，您必须返回MyResult类

 var res = await um.ChangePasswordAsync(user, pass.OldPassword, pass.NewPassword);
    return new MyResult(res);

，然后在视图/组件中使用此代码：
1-定义错误变体：

IEnumerable<IdentityError> PassErrors;

2-在剃须刀代码中使用以下方式：

 @if (PassErrors != null)
   {
       <ul>
           @foreach (var item in PassErrors)
           {  
               <li class="red">                         
                   @item.Description
                   </li>
           }
       </ul>
   }

because UserManager returns IdentityResult , and it has an IEnumrable of Identity Errors
you have to create a new class like Myresult, and get an IdentityResult in its constructor:

using Microsoft.AspNetCore.Identity;
    public class MyResult
    {
        public bool Succeeded { get; set; }
        public IEnumerable<IdentityError> Errors { get; set; }
        public MyResult(IdentityResult res)
        {
            this.Succeeded = res.Succeeded;
            this.Errors = res.Errors;

            foreach (var error in res.Errors)
            {
                var Error = this.Errors.FirstOrDefault(er => er.Code == error.Code);
                switch (error.Code)
                {
                    case "PasswordRequiresUpper":
                        Error.Description = "YOUR OWN MESSAGE.";

                              break;
                    case "PasswordRequiresLower":
                      Error.Description = "YOUR CUSTOM MESSAGE.";
                             break;
                    // ......
                    default:
                        Error.Description = error.Description;
                        break;
                }
            }

        }
    }

and in your controller action or service function, you have to return MyResult class

 var res = await um.ChangePasswordAsync(user, pass.OldPassword, pass.NewPassword);
    return new MyResult(res);

then, in View/component, use this code:
1- define Error variant:

IEnumerable<IdentityError> PassErrors;

2- in razor codes use this:

 @if (PassErrors != null)
   {
       <ul>
           @foreach (var item in PassErrors)
           {  
               <li class="red">                         
                   @item.Description
                   </li>
           }
       </ul>
   }
