C#中string[]数组和list<string>泛型的相互转换 【转】

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();        

}     } }

结果显示：
