Pay special attention to the way 

Length

 is used on the jagged array 

network_nodes

.

Recall, a two-dimensional jagged array is an array of arrays. Thus, when the expression

network_nodes.Length

is used, it obtains the number of 

arrays

 stored in 

network_nodes

, which is four in this case. 

To obtain the length of any individual array in the jagged array, you will use an expression 

such as this:

network_nodes[0].Length

which, in this case, obtains the length of the first array.
