C#中string[]数组和list泛型的相互转换

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：
