Can a two-dimensional array int[,] be a Dictionary value in C#?

Question

.NET

Such a task. There are files containing 1.4 lyama values ​​in the form of a two-dimensional array 1201x1201. Files with a specific type name - N02E128 (this is longitude and latitude).
The essence of the program will be that they set a square on the map with coordinates and it should load into memory all files suitable for the given coordinates, and I will check by deserialized coordinates from the file name.
Well, I decided that the dictionary is suitable to make the names the keys and store these arrays by the keys. But it looks like it can't store a 2D array as a value.
I'm also happy to hear other suggestions on how to store it.

Answer 1

there was a typo, store - maybe.

Answer 2

You can push a tuple into a dictionary
Or describe the class itself, for example

public struct Coordinate {
  public double Longitude { get; set; }
  public double Latitude { get; set; }
}
public class MapPart {
  public string Name { get; set; }
  public ICollection<Coordinate> Coordinates { get; set; }
}
