[Solved] Array comparison and sorting to list c#

by


Try this:

// assuming you'll already have the subjects of the emails
var subjects = new List<string>
{
    "ABC / Vesse / 11371503 /C report",
    "Value/BEY/11371503/A report"
};

var listOfItems = new List<Tuple<string, string, int, string>>();
subjects.ForEach(s =>
{
    var splits = s.Split(new[] {"https://stackoverflow.com/"}, StringSplitOptions.RemoveEmptyEntries).Select(x => x.Trim()).ToArray();

    // Do proper error checking before the int.Parse and make sure every array has 4 elements
    listOfItems.Add(
        new Tuple<string, string, int, string>(splits[0], 
                                                splits[1], 
                                                int.Parse(splits[2]), 
                                                splits[3]));
});

var newList = listOfItems
    .OrderBy(x => x.Item3) // the number
    .ThenBy(x => x.Item4) // {x} report
    .ToList();
