how to sort List<T> in c# / .net

Question

I have a class PropertyDetails:

public class PropertyDetails
{

     public int Sequence { get; set; }

     public int Length { get; set; }

     public string Type { get; set; }
}

I am creating a list of PropertyDetails as

List<PropertyDetails> propertyDetailsList=new List<PropertyDetails>();

I want to sort this list by PropertyDetails.Sequence.

Linq solutions are welcome.

If you want to sort the existing list in-place then you can use the Sort method:

List<PropertyDetails> propertyDetailsList = ...
propertyDetailsList.Sort((x, y) => x.Sequence.CompareTo(y.Sequence));

If you want to create a new, sorted copy of the list then you can use LINQ's OrderBy method:

List<PropertyDetails> propertyDetailsList = ...
var sorted = propertyDetailsList.OrderBy(x => x.Sequence).ToList();

(And if you don't need the results as a concrete List<T> then you can omit the final ToList call.)
