推荐答案

您可以创建列表实例，然后将其传递给''insert''和''删除''方法。例如

You may create the list instance and then pass it to the ''insert'' and ''delete'' methods. e.g.

public static void my_insert(List <string > li)
   {
     li.Add("foo");
     li.Add("boo");
     li.Add("goo");
   }
   public static void my_delete(List<string> li)
   {// deletes all but the very first element
     if (li.Count > 0)
     {
       string s = li[0];
       li.Clear();
       li.Add(s);
     }
   }

   public static void Main()
   {
     List<string> li = new List<string>();
     my_insert(li);
     my_delete(li);
     foreach (string s in li)
     {
       Console.WriteLine(s);
     }
   }

这不是有效的C＃代码。第二行不会编译，它没有任何意义。如果你知道的话，你应该提到这一点。

This is not a valid C# code. The second line won''t compile, and it does not make any sense. If you knew that, you should have mentioned that.
