Asp.net Page_Init（）被调用两次

我的页面的

Page\u Init（）

方法在第一次显示之前被调用了两次。在这两种情况下，IsPostBack==false。我已设置了

AutoEventWireup=“true”

。以下是调用时的两个堆栈跟踪：

差异发生在

System.Web.HttpApplication.ResumeStepsFromThreadPoolThread（）

再次调用

ResumeSteps（）

的地方，最终再次调用

Page_Init（）

。

两件事导致了这种情况发生在我身上

在HTML图像标记中有一个空白的src元素，可以有效地向同一页面发出另一个请求。比如说,

有两件事联系在一起。在VB中，当方法上有一个显式handles子句，并且它也通过设计器连接时，就会发生这种情况。您可能更喜欢显式地连接事件并关闭自动事件连接（这也适用于C）

可能有很多事情，但img标签经常出现。

如果是#1，我应该在F12开发者工具中看到第二个网络请求，对吗？我没有看到#2：我在ASPX中设置了

AutoEventWireup=“false”

，并且

this.Init+=new System.EventHandler（this.Page\u Init）到构造函数，我仍然有相同的结果。@Hillboy，谢谢，我看到了，但似乎没有一个适用。
