的Page_Load被多次调用，如果有在Page_Load中异常 [英] Page_Load is called multiple times if there is an exception in Page_Load

问题描述

我写了下面code

            protected void Page_Load(object sender, EventArgs e)
            {
                if (!Page.IsPostBack)
                {
                    try
                    {
                        string data = Request.Form["postedData"];
                        if(someFunc(data))
                            Response.Redirect(SuccessURL, false);
                        else
                            Response.Redirect(FailureURL, false);
                    }
                    catch (Exception ex)
                    {
                        Response.Redirect(FailureURL, false);
                    }
                }
            }

它工作正常，除非在Page_Load异常。从我的理解code应的页面，FailureURL重定向在异常情况下。但在我的情况下，当有Page_Load中获取与发布的数据为NULL连连称为异常。任何线索？

It works fine unless there is an exception in the Page_Load. From my understanding the code should redirect the page to FailureURL in case of an exception. But in my case when there is an exception Page_Load gets called again and again with posted data as NULL. Any clue?

推荐答案

试着改变你的重定向code这样：

Try changing your redirect code to this:

修改：新增code，以避免ThreadAbortException

EDIT: Added code to avoid ThreadAbortException

Response.Redirect(FailureURL, false); 
HttpContext.Current.ApplicationInstance.CompleteRequest();
