1,从数组转为List<T>,例如：从String[]转到List<String>String[] str={"str","string","abc"};List<String> listS=str.ToList();2, 从List<T>转为数组，例如：从List<String>转到String[]List<String> listS=new List<String>();listS.Add("str");listS.Add("hello");

String[] str=listS.ToArray();

测试代码：

string[] aa = new string[] { "11", "22", "33" };List<string> lists = aa.ToList();foreach (var lt in lists){    Console.WriteLine(lt);}string[] bb = lists.ToArray();foreach (var bt in bb){    Console.Write(bt + "-");}
