对象的排序列表c#

Question

I have list of clients:

Client o = new Client();
List<Client> listO = o.dtGetClients();

I want to sort the listO by UserName , but when I do it by Linq :

List<Client> SortedList = listO
  .OrderBy(X => X.UserName)
  .ToList();

I get a different instance of List<Client> . How can I do it in-place (ie I want listO been sorted, not SortedList )?

Answer 1

The question is a misterious one: "The list...". In case the lost fragment is " should be sorted in-place ":

  Client o = new Client();

  var listO = o.dtGetClients();

  listO.Sort((Comparison<Client>) 
    ((left, right) => String.Compare(left.UserName, right.UserName)));
