在fileinfo名称内按int排序fileinfo列表

Question

I have some trouble to sort a List, I need it to be sorted by the FileInfo.Name attribut, within this name is an interger with unknown length at the very beginning of the string. I need to sort the list by this number.

As my experience it is very difficult to compare two strings by a number within this string, so I could need some help.

This is my list:

I need the list to be sorted from this [1,13,2,3,4,5] into this [1,2,3,4,5,13]

Here is what I have tried so far:

infos.Sort((a, b) => a.Split('-')[0].CompareTo(b.Split('-')[0]));

Of course this can not work as I try to compare strings by numbers....

EDIT: Unfortunaely the solution from Mukund does not work as shown in this image:

You can use this.

infos.OrderBy(x => Convert.ToInt32(x.Split('-')[0]))


class Program11
    {
        static void Main(string [] args)
        {
            var infos = new List<string> { "1-100.jpg", "13-11.jpg", "2-145.jpg", "3-421.jpg", "4-842.jpg", "5-1000.jpg" };

            var orderedList = infos.OrderBy(x => Convert.ToInt32(x.Split('-')[0]));

            foreach (var lstItem in orderedList)
            {
                Console.WriteLine(lstItem);
            }

            Console.ReadKey();
        }
    }

Output:
