从一个列表移动元素到其他列表

Question

List<String> s1; 
List<String> s2; 

我要到n项从S1移动到s2的

say s1={"a","b","c"} 
s2={"d","e","f"} 

移动2个元素从S1到S2将使

s1={"c"} 
s2={"d","e","f","a","b"} 

是什么实现这一目标的好方法？

Answer 1

var s1 = new List<string>() { "a", "b", "c" }; 
var s2 = new List<string>() { "d", "e", "f" }; 
s2.AddRange(s1.Take(2)); 
s1.RemoveRange(0, 2);  

Answer 2

使用项目的索引移动（在这种情况下，0）：

string item = s1[0]; 
s1.Remove(item); 
s2.Add(item);
