C#的委托案例

c#实现(delegate)的委托就不多说了，直接上代码，看代码中的注释：

namespace delegate
{
    delegate void dgsayihi(string name);//声明委托
    delegate void dgdo(string name);
    class program
    {
        static void main(string[] args)
        {
            dgsayihi sayhi = new dgsayihi(saychinesehi);
            dgsayihi sayhi2 = new dgsayihi(sayenglishhi);
            sayhi += sayhi2;//实际上+=相当于delegate.combine, -=相当于delegate.remove

            sayhi("春晓");
            console.readline();
        }
        static void saychinesehi(string name)
        {
            console.writeline("你好:" + name);
        }

        static void sayenglishhi(string name)
        {
            console.writeline("hello:" + name);
        }

    }
}
