Question

我是c＃的新手，也是编程方面的新手。我需要帮助一个我过去一周试图弄清楚的主题。我有3个文件：

控制：这是一个界面，应该包含我的列表方法
ControlImpl：这是接口的实现。
运行时：包含main方法之间的绑定代码和界面实现
Test_main：从哪里调用运行时方法＆＃39; call＆＃39;

问题：控制文件中可以有任意数量的实例（例如：c，c1，c2等），每个实例应该能够调用SetTime（）和Nop（）方法。

我列出了方法SetTime()和Nop()。但是，如何将实例添加到列表中，以便调用时每个实例都应调用其方法？

CONTROL

namespace create_interface
{
 interface Control
 {

    void SetTime(params object[] paramsArr);
    void Nop(params object[] paramsArr);
}

public class CM
{
    Control c = new ControlImpl();
    public List<object> ControlMain()
    {


        List<object> methods = new List<object>();
        methods.Add(new Action<object[]>(c.SetTime));                                
        methods.Add(new Action<object[]>(c.Nop));                    
        return methods;
    }

}

}

ControlImpl：

 namespace create_interface
 {
   public class ControlImpl : Control
   {
    void Control.SetTime(params object[] paramsArr)                       
    {
        Console.WriteLine("inside Control.SetTime {0} ", paramsArr[0]);

    }

    void Control.Nop(params object[] paramsArr)                      
    {
        Console.WriteLine("inside Control.Nop ");

    }
    }
 }

运行时：

 namespace create_interface
  {

public class runtime
{
 public void call(params object[] methodparams)
    {


        if ((methodparams[0].Equals(0)) || (methodparams[0].Equals(1)))
        {
            //List<Control> objectlists = cmObject.ControlObjectList();

            List<object> methods = cmObject.ControlMain();
            //Console.WriteLine(methods.Count);
            Action<object[]> method = (Action<object[]>)methods[(int)methodparams[0]];        //object[]
            object[] args = new object[] { methodparams[1] };
            method(args);
       }            

        else
            Console.WriteLine("wrong ID number entered");
    }

Test_main：

namespace create_interface
{
  class test_main
  {

     static void Main(string[] args)
    {
        long time;
        CallingFunc CF = new CallingFunc();


        Console.WriteLine("enter method ID");
        int methodID = Convert.ToInt32(Console.ReadLine());
        try
        {
            switch (methodID)
            {
                case 0:
                    Console.WriteLine("enter the time in long");
                    time = Convert.ToInt64(Console.ReadLine());
                    CF.call(methodID, time);
                    break;

                case 1:
                    CF.call(methodID, null);
                    break;

               default:
                    Console.WriteLine("you entered wrong method ID or parameters");
                    break;
            }
        }
        catch (Exception e)
        {
            Console.WriteLine(e.Message);
        }
   }
