委托，委托書

委托，委托書

1,Delegate的代碼

public delegate void myDelegate(string str);
public static void HellowChinese(string strChinese)
{
　　Console.WriteLine("Good morning," + strChinese);
　　Console.ReadLine();
}

2,Action:指定那些只有輸入參數，沒有返回值的委托

public static void HellowChinese(string strChinese)
{
　　Console.WriteLine("Good morning," + strChinese);
　　Console.ReadLine();
}

Action<string> action = HellowChinese;
action("Spring.");

3,Func:有返回值！

public static string HelloEnglish(string strEnglish)
{
　　return "Hello." + strEnglish;
}

Func<string, string> f = HelloEnglish;
Console.WriteLine(f("Srping ji"));
Console.ReadLine();
