List 复制

方法一：

      List<string> t = new List<string>(); //original

      List<string> t2 = new List<string>(t.ToArray()); // copy of t

方法二：

 

It is a one liner using LINQ.

      List<string> list1 = new List<string>();
      List<string> list2 = new List<string>();

      // This will copy all the items from list 1 to list 2
      list1.ForEach(i => list2.Add(i));
