我怎样才能捕获 MVC3 异常而不返回空白视图？

我想在重写方法 OnException 中处理异常，代码如下：如果我设置filterContext.ExceptionHandled = true; 返回视图将显示空白视图。我不希望它重定向到 500 页面。那我该怎么办呢？

protected override void OnException(ExceptionContext filterContext)
{
    base.OnException(filterContext);

    var exception = new HttpException(null, filterContext.Exception);
    if (exception.GetHttpCode() == (int)HttpStatusCode.InternalServerError)
    {
        if (WebConstants.systemHandleExceptionList.Contains(filterContext.Exception.GetType()))
        {
            //process the error
            SaveErrorMessage(filterContext.Exception.GetType().Name);

            filterContext.ExceptionHandled = true;
        }
        else
        {
            //record the unhandle message to log
            errorlog.Error("", filterContext.Exception);
        }
    }
}

I want to process the exception in the override method OnException the code like below:
if i set the filterContext.ExceptionHandled = true;
the return view will show a blank view.
i don't want it redirect to the 500 page.
so how could i do?

protected override void OnException(ExceptionContext filterContext)
{
    base.OnException(filterContext);

    var exception = new HttpException(null, filterContext.Exception);
    if (exception.GetHttpCode() == (int)HttpStatusCode.InternalServerError)
    {
        if (WebConstants.systemHandleExceptionList.Contains(filterContext.Exception.GetType()))
        {
            //process the error
            SaveErrorMessage(filterContext.Exception.GetType().Name);

            filterContext.ExceptionHandled = true;
        }
        else
        {
            //record the unhandle message to log
            errorlog.Error("", filterContext.Exception);
        }
    }
}

将标志设置为 true 后，您可以立即将其重定向到不同的页面。请参阅下面的示例

RouteValueDictionary errorRouteValues = new RouteValueDictionary( new { controller = "Error", action = "Action" } );

filterContext.Result = new ActionRedirectResult( errorRouteValues );
filterContext.Cancel = true;

you can redirect it to a different page right after setting the flag to true. See example below

RouteValueDictionary errorRouteValues = new RouteValueDictionary( new { controller = "Error", action = "Action" } );

filterContext.Result = new ActionRedirectResult( errorRouteValues );
filterContext.Cancel = true;
