.NET 中list和数组与字符串的相互转换

数组向字符串

string[] strArr = { "ss", "22as2fas22", "ffsaa", "asdf", "asdd", "77as7" };

string str = string.Join(",",strArr);

字符串向数组

string str="a-bc-d";

string[] strs=str.Split('-');

List向数组

 string [] strEmail=User_List.ToArray();

数组向List

使用数组的toList方法

Lsit向字符串

 List<string> zz = new List<string>（）;

            zz.Add（"11"）;

            zz.Add（"22"）;

            zz.Add（"33"）;

            string kk = string.Empty;

            kk = string.Join（"，"， zz.ToArray（））;

字符串向List

可先转换为数组再转换
