Can I generate a linq expression dynamically in C#?

Question

I\'ve currently got a piece of Linq that looks something like this ;

List childrenToBeRemoved = this.ItemsSource.Where(o => o.ParentID == \"123         


        

Answer 1

If you know the type of your items, you can use reflection :

PropertyInfo parentProp = itemType.GetProperty("ParentKey or whatever");
List childrenToBeRemoved = this.ItemsSource.Where(o => Equals("1234", parentProp.GetValue(o, null))).ToList();
