字符串与List互转

List转字符串，用逗号隔开

List<string> list = new List<string>(); list.Add("a"); list.Add("b"); list.Add("c"); //MessageBox.Show(list.); //LoadModel(); string s = string.Join(",", list.ToArray()); MessageBox.Show(s);

List<test> list = new List<test>(); list.Add(new test("1", "a")); list.Add(new test("2", "b")); list.Add(new test("", "")); list.Add(new test("3", "c")); var a = from o in list select o.test1; var b = from o in list select o.test2; string s1 = string.Join(",", a.ToArray()); string s2 = string.Join(",", b.ToArray()); MessageBox.Show(s1 + "\r\n" + s2);

结果：1,2,,3

      a,b,,c

字符串转List

这里s的分隔符不是“,”而是“， ”，后面有一个空格

string s = "1, 2, 3"; List<string> list = new List<string>(s.Split(new string[] { ", " },

StringSplitOptions.RemoveEmptyEntries)); foreach (string t in list) {     MessageBox.Show("*" + t + "*"); }

这里s的分隔符是“,”

string s = "1,2,3"; List<string> list = new List<string>(s.Split(‘,‘)); foreach (string t in list) {     MessageBox.Show("*" + t + "*"); }

}
