csharp用GetInvocationList方法获得了委托要如何调用

可以通过遍历委托的InvocationList来依次调用每个委托。以下是一个示例代码：

delegate void MyDelegate(string message);

class Program
{
    static void Main(string[] args)
    {
        MyDelegate myDelegate = Method1;
        myDelegate += Method2;
        myDelegate += Method3;

        Delegate[] invocationList = myDelegate.GetInvocationList();

        foreach (MyDelegate del in invocationList)
        {
            del("Hello, world!");
        }
    }

    static void Method1(string message)
    {
        Console.WriteLine($"Method1: {message}");
    }

    static void Method2(string message)
    {
        Console.WriteLine($"Method2: {message}");
    }

    static void Method3(string message)
    {
        Console.WriteLine($"Method3: {message}");
    }
}

输出结果为：

Method1: Hello, world!
Method2: Hello, world!
Method3: Hello, world!
