How can I sort List based on properties of T?

Question

My Code looks like this :

Collection optionInfoCollection = ....
List optionInfoList = new List

If you just want Sort() to work, then you'll need to implement IComparable or IComparable in the class.

If you don't mind creating a new list, you can use the OrderBy/ToList LINQ extension methods. If you want to sort the existing list with simpler syntax, you can add a few extension methods, enabling:

list.Sort(item => item.Name);

For example:

public static void Sort(
    this List source,
    Func selector)
{
    var comparer = Comparer.Default;
    source.Sort((x, y) => comparer.Compare(selector(x), selector(y)));
}
public  static void SortDescending(
    this List source,
    Func selector)
{
    var comparer = Comparer.Default;
    source.Sort((x, y) => comparer.Compare(selector(y), selector(x)));
}
