  • 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();         }     } }
