Convert collection operations from CollectionTracking into IChangeSet or Change from DynamicData.
$ dotnet add package CollectionTracking.DynamicDataThis package was developed to interpret a series of immutable lists (from a business layer) as one mutable lists (in a presentation layer).
In other words, convert IObservable<IEnumerable<T>> to ObservableCollection<T>.
Use CollectionTracker.GetOperations to compare 2 enumerables.
using CollectionTracking;
// (...)
var source = new[] { "B", "C", "A" };
var target = new[] { "A", "B", "C", "D" };
var operations = CollectionTracker.GetOperations(source, target);
foreach (var operation in operations)
{
Console.WriteLine(operation);
}
This code prints the following.
Move 'A' from [2] to [0]
Insert 'D' at [3]
IListUse CollectionTracker.ApplyOperations to apply a series of CollectionOperations on an IList.
var list = source.ToList();
list.ApplyOperations(operations);
This code initializes the list variable with the content being [BCA].
The ApplyOperations modifies that list so that it becomes [ABCD].
This is very useful when manipulating an ObservableCollection bound to a UI component (such as ItemsControl.ItemsSource).
Expose conversion methods to relevant types from the DynamicData library.
using CollectionTracking;
using DynamicData;
// (...)
var source = new[] { "B", "C", "A" };
var target = new[] { "A", "B", "C", "D" };
var operations = CollectionTracker.GetOperations(source, target);
// Convert all changes.
IChangeSet<string> changeSet = operations.ToChangeSet();
// Convert a single change.
Change<string> change = operations[0].ToChange();
