在某些情况下，如果要扩展基类的页面，并且要在基类中执行任何常规操作所有页面的Page OnLoad事件中，因此在这种情况下，您可以使用此方法.

只是一个例子:

In some situation if you want to extend your pages with the base class and in the base class you want to perform any common operation in Page OnLoad event for all pages so in that case you can use this method.

It''s just an example:

public class WebForm1 : MyBaseClass
{
    private void Page_Load(object sender, System.EventArgs e)
    {

    } 
}

public class MyBaseClass : System.Web.UI.Page
{
    protected override void OnLoad(EventArgs e)
    {
       // ... add custom logic here ...

       // Be sure to call the base class OnLoad method!
       base.OnLoad(e);
    }
}
