// Remove elements in mediaFiles1 that are also in mediaFiles2.
Console.WriteLine("Remove duplicates (of mediaFiles2) from the set...");
Console.WriteLine($"\tCount before: {mediaFiles1.Count}");
mediaFiles1.ExceptWith(mediaFiles2);
Console.WriteLine($"\tCount after: {mediaFiles1.Count}");
' Remove elements in mediaFiles1 that are also in mediaFiles2.
Console.WriteLine("Remove duplicates (of mediaFiles2) from the set...")
Console.WriteLine($"{vbTab}Count before: {mediaFiles1.Count}")
mediaFiles1.ExceptWith(mediaFiles2)
Console.WriteLine($"{vbTab}Count after: {mediaFiles1.Count}")
Remarks
This method removes any element in the current SortedSet<T> that is also in other. Duplicate values in other are ignored.
This method is an O(n) operation, where n is the number of elements in the other parameter.
