Elmah 不记录异常

在我的 MVC Web 项目中。我试图向访问者显示自定义错误页面,而不使用 web.config 中的“customerrors”元素。

我可以捕获如下异常

protected void Application_Error(object sender, EventArgs e)
{

    Exception exception = Server.GetLastError();

    bool success = RaiseErrorSignal(exception);

    Response.Clear();

    HttpException httpException = exception as HttpException;

    RouteData 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", "Error404");
                break;
            case 500:
                // Server error.
                routeData.Values.Add("action", "Error500");
                break;

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

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

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

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


}

private static bool RaiseErrorSignal(Exception e)
{
    var context = HttpContext.Current;
    if (context == null)
        return false;
    var signal = ErrorSignal.FromContext(context);
    if (signal == null)
        return false;
    signal.Raise(e, context);
    return true;
}

,但 Elmah 无法记录错误,我也发出错误信号。

In my MVC web project. I am trying to show custom error pages to my visitors without using "custromerrors" element in web.config.

I can catch exceptions like below

protected void Application_Error(object sender, EventArgs e)
{

    Exception exception = Server.GetLastError();

    bool success = RaiseErrorSignal(exception);

    Response.Clear();

    HttpException httpException = exception as HttpException;

    RouteData 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", "Error404");
                break;
            case 500:
                // Server error.
                routeData.Values.Add("action", "Error500");
                break;

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

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

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

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


}

private static bool RaiseErrorSignal(Exception e)
{
    var context = HttpContext.Current;
    if (context == null)
        return false;
    var signal = ErrorSignal.FromContext(context);
    if (signal == null)
        return false;
    signal.Raise(e, context);
    return true;
}

But Elmah cant log errors also i am raising error signal.

我发现了问题,我错过了 web.config 部分。我将“ErrorLog”模块添加到 中。

我还需要将其添加到 中。

添加后,Elmah 开始记录错误。

另外,我不需要调用 ErrorSignal.Raise() 方法,Elmah 可以在没有信号的情况下检测错误。

I found the problem, I missed a web.config section. I added "ErrorLog" module to <system.webserver><modules>.

I also need to add it to <system.web><httpModules>.

After adding, Elmah start to log errors.

Also I don't need to call ErrorSignal.Raise() method, Elmah can detect errors without signalling.
