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");

string s = string.Join(",", list.ToArray());

 

List<Persion> list = new List<Persion>();
list.Add(new Persion("1", "a"));
list.Add(new Persion("2", "b"));
list.Add(new Persion("", ""));
list.Add(new Persion("3", "c"));
var a = from o in list select o.Persion1;
var b = from o in list select o.Persion2;
string s1 = string.Join(",", a.ToArray());
string s2 = string.Join(",", b.ToArray());

字符串转List，这里s的分隔符是“,”

string s = "1,2,3";
List<string> list = new List<string>(s.Split(','));
