Question

I’m in University studying computer science.

This is actually my first big assignment but they haven’t taught us how to do the main bits in it yet.

What I need help with is that my program has to take its information from a .dat source file and use the information within that .dat file to perform its grade calculations etc.
They have not taught us this yet (and i dont think they will before the assignment hand in date), how to take the information from this source file!

The .dat file format contains a string of single characters seperated by whitespace:

A B C A D F E

I would greatly appreciate any assistance that anyone could provide me in this area!

Answer 1

Taken from here (not my work):

StreamReader reader = new StreamReader("MyFile.dat");
string strAllFile = reader.ReadToEnd().Replace("\r\n", "\n").Replace("\n\r", "\n");
string[] arrLines = strAllFile.Split(new char[] { '\n' });
textBox1.Text = arrLines[0];
textBox2.Text = arrLines[2];

That is reading line one from the .dat file and putting it into textbox1, and then reading line 3 and putting that in textbox2 using array.

StreamWriter writer = new StreamWriter("MyFile.dat");
writer.WriteLine("Hello");
writer.WriteLine("World");

That is writing hello and world to two lines in a .dat file.
