List<string>里的集合和字符串互转
1.把List<string>里的集合转换成字符串: List<string> names =newList<string>(){"ccc","xxx","aaa","bbbb"}; names.Sort(); var result =String.Join(",", names.ToArray()); Console.Write(result); 2.字符串怎样转为List<string>集合: string s = "1,2,3"; List<string> list = new List<string>(s.Split(',')); foreach (string t in list) { MessageBox.Show("*" + t + "*"); }
