Page_Init（）被調用兩次

Question

我的網頁Page_Init()方法被稱爲第一次顯示了兩次了。在這兩種情況下，IsPostBack == false。我有AutoEventWireup="true"集。下面是當被呼叫這兩種堆棧跟蹤：

第一次調用：

在該點的差異情況，其中System.Web.HttpApplication.ResumeStepsFromThreadPoolThread()電話ResumeSteps()一次，最終再次撥打Page_Init()。已經造成這發生在我身上

兩件事情;

1. 在HTML圖像標記中有一個空白的src元素，可以有效地向另一個頁面發出另一個請求。例如，
2. 兩批活動的接線。在VB中，當你在一個方法上有一個明確的句柄子句時，它會發生，並且它也通過設計器連接起來。您可能更願意明確地連接事件並關閉自動事件連接（這也適用於C＃）。

這可能是很多事情，但img標籤發生了很多。
