**List<string>和string\[\]数组之间的相互转换,需要的朋友可以参考下**

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：**
