Action与Func的用法及使用

Action与Func的区别：

        Action是一种委托类型，但是不具有返回值。可以支持最大16个参数（网上说支持16个），实际测试支持4个。

        Func也是一种委托类型，但是其有返回值。

private Action action; //Action 用法 private Action<string> action1; private Action<string, string> action2; private Action<string, string, string> action3; private Action<string, string, string, string> action4; private Func<int, string> func; //func 用法 void Start() { action = Fun; action1 = Fun; action2 = Fun; action3 = Fun; action4 = Fun; func = Fun; string name = func(1); Debug.Log(string.Format("Evan Print,{0}", name)); action(); action1("Evan"); action2("Evan","Boy"); action3("Evan","Boy","18"); actio
