C#實現(Delegate)的委託就不多說了，直接上程式碼，看程式碼中的註釋：

namespace Delegate
{
    delegate void DGSayiHi(string name);//宣告委託
    delegate void DGDo(string name);
    class Program
    {
        static void Main(string[] args)
        {
            DGSayiHi sayhi = new DGSayiHi(SayChineseHi);
            DGSayiHi sayhi2 
 
= new DGSayiHi(SayEnglishHi);
            sayhi += sayhi2;//實際上+=相當於Delegate.Combine,-=相當於Delegate.Remove

            sayhi("春曉");
            Console.ReadLine();
        }
        static void SayChineseHi(string name)
        {
            Console.WriteLine("你好:" + name);
        }

        static void
 
 SayEnglishHi(string name)
        {
            Console.WriteLine("Hello:" + name);
        }

    }
}
