C#中的Action＜＞和Func＜＞

【Delegate】委托

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

myDelegate d = new myDelegate(HellowChinese);
d(“ZLL”);

【action<>】指定那些只有输入参数，没有返回值的委托

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

Action action = HellowChinese;
action(“ZLL”);

【func<>】这个和上面的那个是一样的，区别是这个有返回值！

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

Func f = HelloEnglish;
Console.WriteLine(f(“Srping ji”));
Console.ReadLine();
