用C#委托数组 [英] Delegate Array in C#

问题描述

我正在尝试从委托数组中调用委托函数.我已经能够创建代表数组，但是如何称呼代表?

I am experimenting with calling delegate functions from a delegate array. I've been able to create the array of delegates, but how do I call the delegate?

public delegate void pd();

public static class MyClass
{

    static void p1()
    {
        //...
    }

    static void p2 ()
    {
        //...
    }

    //...

    static pd[] delegates = new pd[] {

        new pd( MyClass.p1 ),
        new pd( MyClass.p2)
        /* ... */
    };
}

public class MainClass
{
    static void Main()
    {
        // Call pd[0]
        // Call pd[1]
    }
}

数组的原因是，我需要根据需要通过索引调用委托函数.它们不会响应事件而运行.我在代码中看到一个严重(愚蠢)错误，因为我尝试使用pd []类型而不是数组名称(代理)执行委托函数.

The reason for the array is that I need to call the delegate functions by an index as needed. They are not run in response to an event. I see a critical (stupid) error in my code as I had tried to execute the delegate function using the pd[] type rather than the name of the array (delegates).

推荐答案

如果它们都是同一类型，为什么不将它们组合成一个多播委托呢?

If they're all the same type, why not just combine them into a single multicast delegate?

static pd delegateInstance = new pd(MyClass.p1) + new pd(MyClass.p2) ...;

...
pd();
