How Sort A List By A Part Of That String Desc

Question

i have a list like this :

List list_lines = new List();
list_lines.add(\"name1__pass1__com__14__55\");
list_lines.add(\"name2__pas         


        

Answer 1

If the number always starts after the last underscore character, then this should work:

var sortedList = list_lines
    .OrderByDescending(l => int.Parse(l.Substring(l.LastIndexOf("_") + 1)))
    .ToList();
