I often want to use a list to sort and every time I have to go searching on how to use the IComparer interface.
Assume I have a Person object with the “DisplayName” property that I wish to sort by.
I created the following class:
public class PersonDisplayNameAscendingComparer : IComparer { #region IComparer Members public int Compare(Person x, Person y) { return x.DisplayName.CompareTo(y.DisplayName); } #endregion }
And then assuming you have a List called people, you can sort like this;
PersonDisplayNameAscendingComparer personComparer = new PersonDisplayNameAscendingComparer(); people.Sort(personComparer);
Job done.
