C # list<int> to String and string [] turn list<int>

List<int> Turn string:

List<int>: 1,2,3,4,5,6,7 converted to string: "1,2,3,4,5,6,7"

list<int> list= New List<int> () {1, 2, 3, 4, 5, 6, 7};string depaid = string. Join (",", list);

String turn list<int>:

string s = "1, 2, 3"; list<string> list = new List<string> (S.split (new string[] {","}, Stringsplitoptions.removeemptyentries));
list<string> list = new list<string> (S.split (', '));//or

List<string> Turn list<int>

var listOfStrings =(new[]{"4","5","6"}).ToList();
var listOfInts = listOfStrings.Select<string,int>(q =>Convert.ToInt32(q));

List<int> Turn list<string>

list<int> L1 = new list<int> (new int[] {}); list<string> L2 = L1. convertall<string> (x = x.tostring ());

C # string[] arrays and list<string>:

system.string[] str={"str", "String", "abc"}; list<system.string> lists=new list<system.string> (str);

Transfer from list<system.string> to system.string[]

List<system.string> lists=new list<system.string> (); Lists.add ("str"); Lists.add ("Hello"); System.string[] Str=lists.toarray ();
