C#中List〈string〉和string[]数组之间的相互转换

1,从System.String[]转到List

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

List listS=new List(str);
 

2, 从List转到System.String[]

复制代码
List listS=new List();

listS.Add("str");

listS.Add("hello");

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

 测试：

复制代码
 protected void Page_Load(object sender, EventArgs e)
        {
            System.String[] sA = { "str", "string1", "sting2", "abc" };
            List sL = new List();
            for (System.Int32 i = 0; i < sA.Length; i++)
            {
                Console.WriteLine("sA[{0}]={1}", i, sA[i]);
            }
            sL = new List(sA);
            sL.Add("Hello!");
            foreach (System.String s in sL)
            {
                Response.Write(s);
                Response.Write("
");
                //Console.WriteLine(s);
            }
            System.String[] nextString = sL.ToArray();
            //Console.WriteLine("The Length of nextString is {0}", nextString.Length);
            //Console.Read();
            Response.Write("The Length of nextString is :"+nextString.Length);
        }
复制代码
