Dividing the data in text file into smaller chunks

Question

I am working on this program where I have defined a class value which takes data from a text file. Right now my program is taking the whole data, processes it and then is used in further calculation in Main().

 

I want to divide the incoming data into smaller data chunks and perform the calculation one by one.

For Ex: lets say I have 2048 bits in .txt file, this data gets divided into 4 chunks of 512 bits each. After division Chunk 1 is used in furhter calcualtion in Main(), after that program comes back o pick Chunk 2 and do the calculation and similar with Chunk 3 and Chunk 4. How can I do that? Please advise

 

public static byte[] GetValue()

{

 byte[] numbers = new byte[2048];

 using (FileStream fs = File.Open(@"C:\Users\file1.txt", FileMode.Open, FileAccess.Read, FileShare.ReadWrite))

using (BufferedStream bs = new BufferedStream(fs))

using (StreamReader sr = new StreamReader(bs))

{

string line;

while ((line = sr.ReadLine()) != null)

{

 for (int i = 0; i < 512; i++)

 {

 numbers[i] = Byte.Parse(line[i].ToString());

 }

 }

 }

 return numbers;

}
