Location of a refernced object in an array?

Hey there all

Background:::::
I am working with a massive (2-dimensional) array of a custom neuron type for a Neural Network that seems to work well. When working with the smaller Neuron array sizes e.g.
Neuron[,] NodeList = new Neuron[800,600];
it will serialize fine.

However it gets stuck in some object tree flattening loop(According to some forum in my history) here and runs out of memory
Neuron[,] NodeList = new Neuron[10000,9000]
After a little research on the Google I found that I will have to use another serializer or implement my own way of saving the data.
I opted for a simple data writer as it would be easier





Problem(Skip here if you want :p):::
For my custom data writer i'm writing all the data needed to a file.
In my Neuron type it stores a reference to another Neuron.
All Neurons stored are all in the NodeList array as mentioned (including linked ones)

class Neuron
{
    //Some Old Neuron Info
    float IThreshold = 1;
    float IFiringValue = 1;

    //Link
    float IWeight = 1;
    Neuron NextNeuron;   //This Line HERE
    ...
}

For my data writer I am going through each neuron in the array and storing its info... like location in the array, weighting etc
I also want to store the location where its linked neuron is in the array

I would like to do something like

int NewX = NodeList[x,y].NextNeuron.ParentArrayIndex(0);
int NewX = NodeList[x,y].NextNeuron.ParentArrayIndex(1);

Where the 0 & 1 merely represent the array dimension
Is any of this possible or have a different way of getting it without searching through and checking they equal?

Any help appreciated,... and thank you :)
