如何在Asp.Net Mvc 3中显示自定义错误页面？

我使用这些步骤： / p>

I use these steps:

// in Global.asax.cs:
        protected void Application_Error(object sender, EventArgs e) {

            var ex = Server.GetLastError().GetBaseException();

            Server.ClearError();
            var routeData = new RouteData();
            routeData.Values.Add("controller", "Error");
            routeData.Values.Add("action", "Index");

            if (ex.GetType() == typeof(HttpException)) {
                var httpException = (HttpException)ex;
                var code = httpException.GetHttpCode();
                routeData.Values.Add("status", code);
            } else {
                routeData.Values.Add("status", 500);
            }

            routeData.Values.Add("error", ex);

            IController errorController = new Kavand.Web.Controllers.ErrorController();
            errorController.Execute(new RequestContext(new HttpContextWrapper(Context), routeData));
        }

        protected void Application_EndRequest(object sender, EventArgs e) {
            if (Context.Response.StatusCode == 401) { // this is important, because the 401 is not an error by default!!!
                throw new HttpException(401, "You are not authorised");
            }
        }

AND：

// in Error Controller:
    public class ErrorController : Controller {

        public ActionResult  Index(int status, Exception error) {
            Response.StatusCode = status;
            return View(status);
        }

        protected override void Dispose(bool disposing) {
            base.Dispose(disposing);
        }
    }

和错误文件夹中的索引视图：

AND the index view in Error folder:

@* in ~/Views/Error/Index.cshtml: *@

@model Int32    
@{
    Layout = null;
}    
<!DOCTYPE html>    
<html>
<head>
    <title>Kavand | Error</title>
</head>
<body>
    <div>
        There was an error with your request. The error is:<br />
        <p style=" color: Red;">
        @switch (Model) {
            case 401: {
                    <span>Your message goes here...</span>
                }
                break;
            case 403: {
                    <span>Your message goes here...</span>
                }
                break;
            case 404: {
                    <span>Your message goes here...</span>
                }
                break;
            case 500: {
                    <span>Your message goes here...</span>
                }
                break;
            //and more cases for more error-codes...
            default: {
                    <span>Unknown error!!!</span>
                }
                break;
        }
        </p>
    </div>
</body>
</html>

AND - 最后一步：

AND -the final step:

<!-- in web.config: -->

<customErrors mode="Off"/>
