asp.net-mvc – 处理ASP.NET MVC中的路由错误

如果只将[HandleError]属性添加到类或操作中,MVC将在视图文件夹中查找错误视图.

您还可以添加ErrorController甚至静态页面并将其添加到Web.config：

<customErrors mode="On" >
    <error statusCode="404" redirect="/Error/PageNotFound/" />
</customErrors>

或者您可以在Global.asax.cs中处理HTTP 404并以编程方式路由到ErrorController.这就是我通常这样做的方式：

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

    var routeData = new RouteData();

    if (ex.GetType() == typeof(HttpException))
    {
        var httpException = (HttpException)ex;

        switch (httpException.GetHttpCode())
        {
            case 404:
                routeData.Values.Add("action","PageNotFound");
                break;
            default:
                routeData.Values.Add("action","GeneralError");
                break;
        }
    }
    else
    {
        routeData.Values.Add("action","GeneralError");
    }

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

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