1,从System.String[]转到List<System.String>

System.String[] str={"str","string","abc"};

List<System.String> listS=new List<System.String>(str);

 

2, 从List<System.String>转到System.String[]

List<System.String> listS=new List<System.String>();

listS.Add("str");

listS.Add("hello");

System.String[] str=listS.ToArray();

 

测试如下:

using System; using System.Collections.Generic; using System.Linq; using System.Text;

namespace ConsoleApplication1 { class Program { static void Main(string[] args) { System.String[] sA = { "str","string1","sting2","abc"}; List<System.String> sL = new List<System.String>(); for (System.Int32 i = 0; i < sA.Length;i++ ) { Console.WriteLine("sA[{0}]={1}",i,sA[i]); } sL = new List<System.String>(sA); sL.Add("Hello!"); foreach(System.String s in sL) { Console.WriteLine(s); } System.String[] nextString = sL.ToArray(); Console.WriteLine("The Length of nextString is {0}",nextString.Length); Console.Read(); } } }
