代表阵列 [英] Delegate Array

问题描述

我从一个委托调用数组功能委托试验。我已经能够创建代表的数组，但如何调用该委托？

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]
    }
}

编辑：的原因阵列是我需要通过一个索引根据需要调用该委托功能。它们不响应于一个事件运行。我看到我的code关键（愚蠢）误差作为我曾试图用PD []类型，而不是阵列（代表）的名称来执行委托功能。

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

如果他们都是同一类型的，为什么不将它们组合成一个单一的多播委托？

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();
