N00b Question

[Splatter]

I use C# to write code, and I ran into an issue with Diablo 3 that I though could be solved through memory reading, however I am quite new to memory reading. I decided that the best way to get aquainted with it was to write my own program, then attempt to read the memory of that program.
So, I wrote a simple program that has a public class sompin, with three members Name, Text, Corn... I then created a list of 100 sompin's each object of type sompin had values of Name+5 random characters, Text+5random characters Corn+5 random characters. Once that was complete, I did a readkey() so that the program would pause execution, then after a key is entered it would print the values of each sompin to ensure that GC and/or optimization would not remove them. (I am not 100% sure how necessary the last part was). (This was a console application)

I then created a second,Windows Forms, application that used Process.GetAllProcesses() to populate a list box, selecting a process from the list box would show the PrivateMemorySize, the VirtualMemorySize, and the Working Memory Size. Then upon clicking a button it wrote to a file a "Memory dump" of the proces. To do this I used ReadProcessMemory, one byte at a time for a number of bytes equal to each of those sizes(In three seperate runs of the program) (I didn't read it all at once because I got a 299 partial read error attempting that). For each byte read through ReadProcessMemory, I wrote the byte cast as a char to a file (unless i received a partialMemoryError or a null in which case I wrote a Space " ".

I expected to find 100 instances of Corn\s{5} somewhere in the memory dump. This is not the case, I found only 3 instances of each of that word, only one of them being an actual value of a list item (The last one).

Does anyone know where I went wrong? Or have any advice as to what is happening?
