Page_Init（）被调用两次

Question

我的网页Page_Init()方法被称为第一次显示了两次了。在这两种情况下，IsPostBack == false。我有AutoEventWireup="true"集。下面是当被呼叫这两种堆栈跟踪：

第一次调用：

在该点的差异情况，其中System.Web.HttpApplication.ResumeStepsFromThreadPoolThread()电话ResumeSteps()一次，最终再次拨打Page_Init()。已经造成这发生在我身上

Answer 1

两件事情;

1. 在HTML图像标记中有一个空白的src元素，可以有效地向另一个页面发出另一个请求。例如，
2. 两批活动的接线。在VB中，当你在一个方法上有一个明确的句柄子句时，它会发生，并且它也通过设计器连接起来。您可能更愿意明确地连接事件并关闭自动事件连接（这也适用于C＃）。

这可能是很多事情，但img标签发生了很多。
