public void ActionDemo(List<int> list){

}
}
}



public class CSharpDemo : MonoBehaviour {

Action action;


// Use this for initialization
void Start () {

DemoAction demo = new DemoAction();
demo.action = TestAction;
demo.action1 = TestAction;
demo.action2 = TestAction;
demo.action3 = TestAction;

List<int> list = new List<int>(){10,20,30,40};
demo.action();
demo.action1(20);
demo.action2(20, "rose_grils");
demo.action3(list);

}

// Update is called once per frame
void Update () {

}


/// <summary>
/// 不带参数
/// </summary>
void TestAction(){
Debug.LogError(" 不带参数");
}

/// <summary>
/// 带一个参数
/// </summary>
/// <param name="a"></param>
void TestAction(int a)
{
Debug.LogError("带一个参数 = " + a);
}

/// <summary>
/// 带2个参数
/// </summary>
/// <param name="a"></param>
/// <param name="str"></param>
void TestAction(int a, string str)
{
Debug.LogError("带2个参数a = " + a + " str = " + str);
}

/// <summary>
/// 带一个列表
/// </summary>
/// <param name="list"></param>
void TestAction(List<int> list)
{
Debug.LogError("带一个列表");
for (int i = 0; i < list.Count; i++)
{
Debug.LogError("i = " + list[i]);
}
}

}

运行结果如下图：
