C# How to split a dictionary into an array of keys and an array of values?

Question

C++ / C#

There is a dictionary:

Dictionary<float, string> ObjectsOnSceneInDict = .....

It should be split into 2 arrays:

float[] DistanceToObjects = new float[360];
String[] TypeObjectsString = new String[360];

I tried a couple of options from the Internet, but did not find the answer.
Please help. Not a pro in C#...

Answer 1

float[] DistanceToObjects = ObjectsOnSceneInDict.Keys.ToArray();
string[] TypeObjectsString = ObjectsOnSceneInDict.Values.ToArray();

But why?
