C# Array of dictionaries with defined dimensions

I'm trying to define a custom type for my project. I will try to explain what I'm trying to achieve. I have n*m packets. each packet has a different composition (mass of CO2, H2O, NO, CO , ...). I want to store the composition of all packets in my custom type. The composition of each packet can be a Dictionary like this:

Dictionary<string, double>

as an example :

packetComposition["CO2"]  = 2.6;
packetComposition["O2"]  = 1.7;

The point is that all these dictionaries should be stored in some sort of nm array. So I can have composition of all nm packets in one place.

Obviously this array can't be something like double[,] or int[,] , ... because the content will be a dictionary and not an int or double.

Any idea how to store all these dictionaries in a custom type of n*m dimension? Thanks

You could create your own packet type which will contain all the compounds, for example

 public class Packet
 {
      public Dictionary<string, decimal> Compounds { get; }

      public Packet()
      {
           Compounds = new Dictionary<string, decimal>();
      }
 }

And you can use it like this

List<Packet> packets = new List<Packet>();

Packet packet = new Packet();
packet.Compounds.Add("CO2", 2.6);
packet.Compounds.Add("O2", 1.7);

packets.Add(packet);

You can certainly use a Dictionary<string, double>[,] to hold your data:

var packets = new Dictionary<string, double>[2, 3]
{
    { new Dictionary<string, double>(), new Dictionary<string, double>(), new Dictionary<string, double>(), },
    { new Dictionary<string, double>(), new Dictionary<string, double>(), new Dictionary<string, double>(), },
};

packets[1, 0]["CO2"] = 2.6;
packets[1, 1]["CO2"] = 2.4;
packets[1, 2]["CO2"] = 2.9;

You should create your own class for this. Then you can easily create instances and put them into a list:

class Composition
{
    public string Name { get; set; }
    public double Value { get; set; }
}

Now put them into a multidemensional array:

Composition[,] myInstances = new Composition[n,m];
myInstanes[0,0] = new Composition { Name = "CO2", Value = 2.6 };
myInstanes[0,1] = new Composition { Name = "O2", Value = 1.7 };
