How to sort list by 2 columns

Question

I have a list created from a log file and I need to sort it.

I have tried list.OrderBy() but it gives me errors and is not working.

List<string[]> list = new List<string[]>();
var logFile = File.ReadAllLines(Name1);
foreach (var item in logFile)
{
   list.Add(new string[] { date_check(item), time_check(item),logType(item), device(item), rest(item) });
}

I need to sort this list by date and time. How can I do it?

Can you update your question with which type of error generated? — A.M. Patel, Dec 28 '18 at 04:35

you can try like this

 var sortList = list.OrderBy(a => a.date_check).ThenBy(a => a.time_check).ToList();

i get this error : Severity Code Description Project File Line Suppression State Error CS1061 'string[]' does not contain a definition for 'date_check' and no extension method 'date_check' accepting a first argument of type 'string[]' could be found (are you missing a using directive or an assembly reference?)

found it : var sortList = list.OrderBy(arr => arr[0]).ThenBy(arr => arr[1]).ToList(); – DanH. Dec 28 '18 at 04:56

acording to Vinoth answer this one worked for me:

var sortList = list.OrderBy(arr => arr[0]).ThenBy(arr => arr[1]).ToList();
