我正在制作我的宠物项目以熟悉 asp.net core mvc。最初，有一个控制器User负责与用户一起工作（注册、授权、密码更改和退出），还有一个方法Login负责登录。有一次，我想将控制器的名称从 to 更改为User，Account将方法的名称从Loginto更改为Sigin，并且尽可能地替换链接。基本上我有两个问题：

  1. 如果需要更改控制器或方法的名称怎么办，然后在整个项目中查找旧名称并更改为新名称（Startup设置时的视图、代码、类CookieAuthenticationOptions）
  2. 如果项目已经发展到 >=10 个控制器并且在每个控制器中 >=5 个方法HttpGet，并且您无法记住所有这些控制器，您需要调用其中一个，该怎么办。

这是我解决问题的方法

    public static class LinksConstants
        {
            public static class Account
            {
                public const String Controller = "Account";
                public const String SignUpActionName = "SignUp";
                public const String SignInActionName = "SignIn";
                public const String ChangePasswordActionName = "ChangePassword";
                public const String SignOutActionName = "SignOut";
                public static readonly String SignUpLink;
                public static readonly String SignInLink;
                public static readonly String ChangePasswordLink;
                public static readonly String SignOutLink;

                static Account()
                {
                    String mask = "/{0}/{1}";

                    SignUpLink = String.Format(mask , Controller , SignUpActionName);
                    SignInLink = String.Format(mask , Controller , SignInActionName);
                    ChangePasswordLink = String.Format(mask , Controller , ChangePasswordActionName);
                    SignOutLink = String.Format(mask , Controller , SignOutActionName);
                }
            }
        }

        public class AccountController : Controller
        {
            [HttpGet, AllowAnonymous, ActionName(LinksConstants.Account.SignInActionName)]
            public async Task<IActionResult> SignInView([FromServices] SignInManager signInManager ,
                                                        [FromQuery] String returnUrl = null)
            {
                //do work
            }
        }
    <div class="clearfix">
        <a class="float-right"  asp-route-returnUrl="@Model.ReturnUrl" asp-controller=@LinksConstants.Account.Controller asp-action=@LinksConstants.Account.SignUpActionName>Create account</a>
    </div>

您如何在实际项目中解决此类问题？

模型

public sealed class SignInViewModel
    {
        #region Fields
        public static readonly SignInViewModel Empty;

        [Required]
        [DataType(DataType.EmailAddress)]
        [EmailAddress]
        [Display(Name = "Email")]
        public String Email { get; set; }

        [Required]
        [DataType(DataType.Password)]
        [Display(Name = "Password")]
        [Remote(action: LinksConstants.RemoteValidation.ValidationPasswordActionName , controller: LinksConstants.RemoteValidation.Controller)]
        public String Password { get; set; }


        [ScaffoldColumn(false), ValidateNever]
        public String ReturnUrl { get; set; }
        #endregion Fields

        static SignInViewModel()
        {
            Empty = new SignInViewModel()
            {
                ReturnUrl = "/"
            };
        }

        public async Task ValidationOnServer(ModelStateDictionary modelState , UserManager userManager)
        {
            UserEntity user = await userManager.FindByEmailAsync(Email);
            if (user is null || !await userManager.CheckPasswordAsync(user , Password))
            {
                String message = "Invalid email or password";
                modelState.TryAddModelError(nameof(Email) , message);
                modelState.TryAddModelError(nameof(Password) , message);
            }
        }

    }

看法

@using WebContacts.Models.Account;

@model SignInViewModel
@section Scripts
{
    <partial name="_ValidationScriptsPartial" />
}
