i need to store my 2D depth array data into a text file.

Why? Just use Data Contract and all will be stored and loaded for you automatically and without much of your effort. As a bonus, you will see how a cultured and well-readable XML or JSON storage looks like.

Please see:

I say, use Data Contact. I will store/load it in a text file. XML and JSON are text file. But if you want to develop your own persistence -- you got my approval, go ahead. But "I want" without any motivation hardly can impress anyone... :-)

Store each row of the array on a separate line. All columns of a row will thus have to placed on one line. Separate each of the column values with a suitable separator, i.e. a character or a string that cannot be part of any given value. If your array only contains numbers the choice of the column separator is easier to solve, just take a space or a tab character. Still begs the question what you are trying to achieve by that, but that can only answered by yourself. :)

If you want to store the values in a human-friendly format (since you are using text file, I assume that) the you may write 'verbosely' each item, e.g.
a[0][0] = 5
a[0][1] = 7
..
a[1][0] = 27
a[1][1] = -7
..


(see How to: Write to a Text File[^]).

On the other hand, if you need to store the array for later retrieval in you program then you may prefer serialization[^].
