Question

I have a list of a class like this :

 public class CityCodeInfo
 {
    public string CityName;
    public string Province;
    public string Code; 
  }

  List<CityCodeInfo> lstCityt = new List<CityCodeInfo>();

How can i sort this list by any of its variables (cityname, province and code)

i’ve tried this code:

  lstCityt.Sort((x, y) => string.Compare(x.CityName, y.CityName));

but it doesn’t work…

Any Idea?!

Answer 1

You can use LINQ for it.

Ascending Order

var result = lstCityt.OrderBy(C=> C.CityName).ThenBy(C=> C.Province).ThenBy(C=> C.Code);

Descending Order

var result = lstCityt.OrderByDescending(C=> C.CityName).ThenByDescending(C=> C.Province).ThenByDescending(C=> C.Code);

Both

var result = lstCityt.OrderBy(C=> C.CityName).ThenByDescending(C=> C.Province).ThenByDescending(C=> C.Code);
