Question

对于标准错误，我使用解决方案错误句柄（请参见下面的代码），并且我尝试了THIS（无效）

Global.asax.cs

 protected void Application_Error(object sender, EventArgs e)
 {
        var exception = Server.GetLastError();

        var httpException = exception as HttpException;
        var routeData = new RouteData();

        routeData.Values.Add("controller", "Error");

        if (httpException == null)
            routeData.Values.Add("action", "Index");
        else //It's an Http Exception, Let's handle it.
            switch (httpException.GetHttpCode())
            {
                case 404:
                    // Page not found.
                    routeData.Values.Add("action", "HttpError404");
                    break;
                case 500:
                    // Server error.
                    routeData.Values.Add("action", "HttpError500");
                    break;

                // Here you can handle Views to other error codes.
                // I choose a General error template  
                default:
                    routeData.Values.Add("action", "General");
                    break;
            }

        // Pass exception details to the target error View.
        routeData.Values.Add("error", exception);

        var request = Request;
        // Pass request details to the target request View.
        routeData.Values.Add("request", request);

        // Clear the error on server.
        Server.ClearError();

        // Avoid IIS7 getting in the middle
        Response.TrySkipIisCustomErrors = true;

        // Call target Controller and pass the routeData.
        IController errorController = new ErrorController();
        errorController.Execute(new RequestContext(
            new HttpContextWrapper(Context), routeData));
}

ErrorController

public class ErrorController : Controller
{
    private readonly ILog _log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);

    // GET: Error
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult HttpError404(string error, HttpRequest request)
    {
        ViewBag.Title = "Page not found (Error 404)";
        ViewBag.Description = error;
        return View("~/Views/Shared/Error.cshtml");
    }

    public ActionResult HttpError500(string error, HttpRequest request)
    {
        ViewBag.Title = "Internal server error (Error 500)";
        ViewBag.Description = error;
        return View("~/Views/Shared/Error.cshtml");
    }

    public ActionResult General(string error, HttpRequest request)
    {
        ViewBag.Title = "Internal server error";

        ViewBag.Description = error;
        return View("~/Views/Shared/Error.cshtml");
    }
}

Error.cshtml

@{
    Layout = "_Layout.cshtml";
}

<div class="row">
    <div class="exceptionmessage col-md-12 text-center">
        <div class="center-block">
            <img src="~/Content/i/404.png" class="img-responsive"/>
        </div>

        <strong>@ViewBag.Message</strong>
        <span class="center-block small text-uppercase">@ViewBag.Main</span>


        <div class="center-block">@Html.ActionLink("Return to the Homepage", "Index", "Home", null, new {@class = "btn btn-primary"})</div>
    </div>
</div>

我有一个目录Techs，其中有一些XML文件（用于加载数据，例如本地DB），并且在web.config中使用此脚本，我无法访问该文件夹并从中下载文件此文件夹（或当我编写不存在的URL或类似文件的www.test.com/afsdfgsdfg.pdf时）时，如果没有从下面的错误处理程序代码重定向到我的自定义错误404页，则找不到IIS消息404页。

  <system.web>    
    <customErrors mode="On" defaultRedirect="~/Error">
      <error redirect="~/Error/HttpError404" statusCode="404" />
    </customErrors>
  </system.web>

  <system.webServer>    
    <security xdt:Transform="Replace">
      <requestFiltering>
        <hiddenSegments>
          <add segment="Techs" />
        </hiddenSegments>
      </requestFiltering>
    </security>
  </system.webServer>

有什么方法可以处理未找到404页的所有错误（同一页而不是两个不同的页）？

谢谢

编辑：

我将ErrorController的新路由添加到RouteConfig.cs中：

routes.MapRoute("Error",
                "{controller}/{action}/",
                new { controller = "Error", action = "HttpError404" });

之后，我将web.config更改为：

<customErrors mode="On" defaultRedirect="~/Error/General">
    <error redirect="~/Error/HttpError404" statusCode="404" />
    <error redirect="~/Error/HttpError500" statusCode="500" />
</customErrors>

<httpErrors errorMode="Custom" existingResponse="Replace">
      <remove statusCode="404" />
      <error
        statusCode="404"
        path="/Error/HttpError404"
        responseMode="ExecuteURL"/>
    </httpErrors>

但是它仍然无法正常工作，例如，在我编写以下内容时，出现了 HTTP错误404.0-找不到或 HTTP错误403.14-禁止等消息，

web.com/Techs /
web.com/Techs/catalog.csv
web.com/Techs.pdf->重定向到404页面
web.com/Home/c.pdf

我的解决方案

我没有向RouteConfig.cs添加任何新路由，仅在下面编辑文件。我调用不带参数的方法的控制器，我得到了不同的对待。 Global.asax.cs和ErrorController的用法与上面相同。

Web.config

<system.web>   
    <customErrors mode="On" defaultRedirect="~/Error/General">
      <error redirect="~/Error/HttpError404" statusCode="403" />
      <error redirect="~/Error/HttpError404" statusCode="404" />
      <error redirect="~/Error/HttpError500" statusCode="500" />
    </customErrors>

  </system.web>

  <system.webServer>
    <httpErrors errorMode="Custom" existingResponse="Replace">
      <remove statusCode="403" />
      <remove statusCode="404" />
      <remove statusCode="500" />
      <error
        statusCode="403"
        path="/Error/HttpError404"
        responseMode="ExecuteURL" />
      <error
        statusCode="404"
        path="/Error/HttpError404"
        responseMode="ExecuteURL" />
      <error
        statusCode="500"
        path="/Error/HttpError500"
        responseMode="ExecuteURL" />
    </httpErrors>
  </system.webServer>

Answer 2

在 web.config 中添加此行

<system.web>
    <customErrors mode="On" defaultRedirect="~/ErrorHandler/Index">
        <error statusCode="404" redirect="~/ErrorHandler/NotFound"/>
    </customErrors>
<system.web/>

编辑：那应该涵盖该代码的所有错误...但是我看到您已经拥有了。
