ArrayList、string、string[]之间的转换
1、ArrarList 转换为 string[] :
ArrayList list = new ArrayList();
list.Add("aaa");
list.Add("bbb");
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");
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(',') ) ;
whatever is worth doing is worth doing well...
