asp.net MVC3上的自定義錯誤頁面我正在開發一個MVC3基礎網站，我正在尋找一個處理錯誤的解決方案，并為每種錯誤渲染自定義視圖。因此，假設我有一個“錯誤”控制器，其主要操作是“索引”（通用錯誤頁面），并且此控制器將針對用戶可能出現的錯誤（如“Handle500”或“HandleActionNotFound”）執行更多操作。因此，網站上可能發生的每個錯誤都可能由此“錯誤”控制器處理（例如：“Controller”或“Action”未找到，500,404，dbException等）。我使用Sitemap文件來定義網站路徑（而不是路由）。這個問題已經回答了，這是對Gweebz的回復我的最終applicaiton_error方法如下：protected void Application_Error() {//while my project is running in debug modeif (HttpContext.Current.IsDebuggingEnabled && WebConfigurationManager.AppSettings["EnableCustomErrorPage"].Equals("false")){
Log.Logger.Error("unhandled exception: ", Server.GetLastError());}else{
try
{
var exception = Server.GetLastError();
Log.Logger.Error("unhandled exception: ", exception);
Response.Clear();
Server.ClearError();
var routeData = new RouteData();
routeData.Values["controller"] = "Errors";
routeData.Values["action"] = "General";
routeData.Values["exception"] = exception;
IController errorsController = new ErrorsController();
var rc = new RequestContext(new HttpContextWrapper(Context), routeData);
errorsController.Execute(rc);
}
catch (Exception e)
{
//if Error controller failed for same reason, we will display static HTML error page
Log.Logger.Fatal("failed to display error page, fallback to HTML error: ", e);
Response.TransmitFile("~/error.html");
}}}

這是我如何處理自定義錯誤的示例。我定義了一個ErrorsController處理不同HTTP錯誤的動作：
public class ErrorsController : Controller{
public ActionResult General(Exception exception)
{
return Content("General failure", "text/plain");
}
public ActionResult Http404()
{
return Content("Not found", "text/plain");
}
public ActionResult Http403()
{
return Content("Forbidden", "text/plain");
}}然后我訂閱了Application_Errorin Global.asax并調用了這個控制器：
protected void Application_Error(){
var exception = Server.GetLastError();
var httpException = exception as HttpException;
Response.Clear();
Server.ClearError();
var routeData = new RouteData();
routeData.Values["controller"] = "Errors";
routeData.Values["action"] = "General";
routeData.Values["exception"] = exception;
Response.StatusCode = 500;
if (httpException != null)
{
Response.StatusCode = httpException.GetHttpCode();
switch (Response.StatusCode)
{
case 403:
routeData.Values["action"] = "Http403";
break;
case 404:
routeData.Values["action"] = "Http404";
break;
}
}
IController errorsController = new ErrorsController();
var rc = new RequestContext(new HttpContextWrapper(Context), routeData);
errorsController.Execute(rc);}

您也可以在Web.Config文件中執行此操作。這是一個適用于IIS 7.5的示例。
<system.webServer> <httpErrors errorMode="DetailedLocalOnly" defaultResponseMode="File"> <remove statusCode="502" subStatusCode="-1" /> <remove statusCode="501" subStatusCode="-1" /> <remove statusCode="412" subStatusCode="-1" /> <remove statusCode="406" subStatusCode="-1" /> <remove statusCode="405" subStatusCode="-1" /> <remove statusCode="404" subStatusCode="-1" /> <remove statusCode="403" subStatusCode="-1" /> <remove statusCode="401" subStatusCode="-1" /> <remove statusCode="500" subStatusCode="-1" /> <error statusCode="500" path="/notfound.html" responseMode="ExecuteURL" /> <error statusCode="401" prefixLanguageFilePath="" path="/500.html" responseMode="ExecuteURL" /> <error statusCode="403" prefixLanguageFilePath="" path="/403.html" responseMode="ExecuteURL" /> <error statusCode="404" prefixLanguageFilePath="" path="/404.html" responseMode="ExecuteURL" /> <error statusCode="405" prefixLanguageFilePath="" path="/405.html" responseMode="ExecuteURL" /> <error statusCode="406" prefixLanguageFilePath="" path="/406.html" responseMode="ExecuteURL" /> <error statusCode="412" prefixLanguageFilePath="" path="/412.html" responseMode="ExecuteURL" /> <error statusCode="501" prefixLanguageFilePath="" path="/501.html" responseMode="ExecuteURL" /> <error statusCode="502" prefixLanguageFilePath="" path="/genericerror.html" responseMode="ExecuteURL" /> </httpErrors></system.webServer>
