1、ArrarList 转换为 string[] :

  ArrayList list = new ArrayList();

  list.Add("aaa");

  list.Add("bbb");

  //转换成数组

  string[] arrString = (string[])list.ToArray(typeof( string)) ;

  2、string[] 转换为 ArrarList :

  ArrayList list = new ArrayList(new string[] { "aaa", "bbb" });

  3、ArrayList 转换为 string :

  ArrayList list = new ArrayList();

  list.Add("aaa");

  list.Add("bbb");

  //转换成数组

  string str= string.Join(",", (string[])list.ToArray(typeof( string)));

  4、string 转换为 ArrayList :

  string str="1,2,3,4,5";

  ArrayList b = new ArrayList( str.Split(',') ) ;
