[C#] Sort Asc/Desc

References

How can I sort generic list DESC and ASC?

Sources

1. Use Linq

var ascendingOrder = li.OrderBy(i => i);

var descendingOrder = li.OrderByDescending(i => i);

2. Not use Linq

li.Sort((a, b) => a.CompareTo(b)); // ascending sort

li.Sort((a, b) => -1* a.CompareTo(b)); // descending sort

3. Make to list.

li = li.OrderBy(i => i).ToList();
