从用户控制页面访问父页面常量变量

[英]access parent page constant variable from user control page

我们可以从child(User control)页面加载事件中访问在页面加载上方声明的父页面const变量吗?

 public const int ConstantCollection = 3;

Yes you can, if your constant is public . 是的,如果您的常量是public ,则可以。

<NameOfThePageClass>.<YourConstantName>

Constant variables behave like static variables, with the exception that you can't change them. 常量变量的行为类似于静态变量,但不能更改它们。

Since your asp.Net page is a class after all, you can access your constant as you would access it if it was in a standard class. 由于您的asp.Net页毕竟是一个类,因此可以访问常量,就像访问标准类中的常量一样。

Example: 例:

public class MyWebPage
{
    public const string myConst = "test";
}

to access it: 访问它:

public void MyMethodSomewhereInAClass()
{
    this.text = MyWebPage.myConst;
}
