Sort list of objects on one of the object's Properties

I have a list of objects List<MyObject> and I want to have this list sorted based on one of the properties of MyObject. So, for example

MyObject obj1, obj2, obj3 = new MyObject();
obj1.Value = 0.2;
obj2.Value = 2.2;
obj3.Value = 1.3;

..the order of the List<> would be

List[0] = obj2;
List[1] = obj3;
List[2] = obj1;

Can I do this using .NET native functions or must I write my own search?

Solution

  • 1 Option OrderBy

    yourList = yourList.OrderBy(x=>x.PropertyName).ToList();

    descending

    yourList = yourList.OrderByDescending(x=>x.PropertyName).ToList();

    2 Option List.Sort

    yourList.Sort((x,y)=>x.PropertyName.CompareTo(y.PropertyName));

    descending

    yourList.Sort((x,y)=>-x.PropertyName.CompareTo(y.PropertyName));
