So I have a dictionary of the form Dictionary<int, Dictionary<int, Object>> myObjects and I would like to flatten this to a List<Object> flattenedObjects as simply as possible. I tried to come up with a clever solution, but so far all I've gotten to work is a solution with two nested foreach -loops that iterate over all of the elements, but I suppose there should be a nicer way of accomplishing this with LINQ.

How to flatten a list using LINQ C#? Flattening a list means converting a List<List<T>> to List<T>. For example, let us consider a List<List<int>> which needs to be converted to List<int>. The SelectMany in LINQ is used to project each element of a sequence to an IEnumerable<T> and then flatten the resulting sequences into one sequence.
There are many reasons you would need a flattened dictionary. One is that it makes it simpler to compare two dicts. The other is that it’s easier to navigate and manipulate it, since a flat structure is one level deep. Python is a versatile language, meaning you can achieve the same goals in several ways.

The SelectMany in LINQ is used to project each element of a sequence to an IEnumerable<T> and then flatten the resulting sequences into one sequence. That means the SelectMany operator combines the records from a sequence of results and then converts it into one result.
try this
List<Object> flattenedObjects = myObjects.Values.SelectMany(myObject => myObject.Values).ToList();
Like this:
var result = myObjects.Values.SelectMany(d => d.Values).ToList();
