从委托中读取返回值

Question

我不确定我是否正确理解了委托的用法,但我想在发布者类中阅读委托返回值.下面的示例如下所示.

//Publisher class
    public class ValidateAbuse
    {

    public delegate List<String> GetAbuseList();
    public static GetAbuseList Callback;

    public void Ip(string ip)
    {
    //   I would like to read GetAbuseList value (List<String>) here. How to do that?
    }

    }


//Subscriber class
    class Server
    {

        public static void Start()
        {
            ValidateAbuse.Callback = GetIpAbuseList;
            ValidateAbuse.Ip(MyIp);
        }

        private static List<string> GetIpAbuseList()
        {
            //return List<String> to ValidateAbuse class and use return value in public void Ip(string ip) method 
        }

Answer 1

public void Ip(string ip)
{
  if (Callback != null)
  {
    List<String> valueReturnedByCallback = Callback();
  }
}
