从调用内联code原有的Page_Load功能 [英] Calling the original Page_Load function from inline code

问题描述

我喜欢猴子修补一个ASPX的网站，这样我可以编译的程序集内添加内容到Page_Load方法。

I like to Monkey patch a ASPX website so that I can add stuff to the Page_Load method within a compiled assembly.

我首先想到的是添加含有第二Page_Load方法的ASPX文件，像这样的脚本标记：

My first thought was to add a script tag containing a second Page_Load method to the ASPX file like so:

<script language="CS" runat="server">
void Page_Load(object sender, System.EventArgs e) 
{
     // do some stuff in addition to the original Page_Load method
}
</script>

但它看起来像只从内嵌code Page_Load方法将被执行，而不是从原来的code-隐藏文件（编译的程序集内）的人。

But it looks like only the Page_Load method from the inline code will be executed and not the one from the original code-behind file (within the compiled assembly).

是否有可能从我的直列code调用原始的方法是什么？或者是有添加的东西，应该直接运行Page_Load方法是从所谓的内联code，而无需修改现有的装配后的任何其他方式？

Is it possible to call the original method from within my inline code? Or is there any other way to add stuff that should run directly after the Page_Load method was called from within inline code without modifying the existing assembly?

推荐答案

在asp.net模型是在.aspx文件中声明的页面actally从它继承自类的子类系统.Web.UI.Page 在.aspx.cs文件中声明。

The asp.net model is that the page declared in the .aspx file is actally a descendant class from the class that inherits from System.Web.UI.Page declared in the .aspx.cs file.

所以，你的Page_Load方法被调用，因为它基本上隐藏了原来的Page_Load方法。下面这个逻辑，你可以这样做：

So your Page_Load method is called because it basically hides the original Page_Load method. Following that logic, you could do:

<script language="CS" runat="server"> 
void Page_Load(object sender, System.EventArgs e)  
{      
   base.Page_Load(sender, e);
   // do some stuff in addition to the original Page_Load method 
} 
</script> 

有没有可访问性问题，因为asp.net默认情况下宣布的Page_Load和类似的方法，如保护这样子类可以调用它。

There are no accessibility issues because asp.net by default declares Page_Load and similar methods as protected so descendant classes can call them.
