stream reader/stream writer if you want it to be a text file or binary read/writer for binary files (.dat or w/e)

Example code...

Code:

            StreamReader SR = new StreamReader(File.Open("filename.txt", FileMode.Open));
            string AllFile = SR.ReadToEnd();
            string[] FileLines = AllFile.Split('\n');
            foreach (string S in FileLines)
                Console.WriteLine(S);
            SR.Close();

Here's an example of a writer

Code:

            StreamWriter SW = new StreamWriter(File.Open("filename.txt", FileMode.OpenOrCreate));
            SW.WriteLine("Line 1");
            SW.WriteLine("Line 2");
            SW.WriteLine("Line 3");
            SW.Flush();
            SW.Close();

VERY basic applications of both systems but hopefully it gives you some ideas.

Code:

string in;
while (!SR.EndOfFile) {
    in = SR.ReadLine();
}

Easier way to read each line of the file.

thank you! I'm gonna try this, I'm just a beginner on c#.

edit:
This code is for opening a file but my main problem for now is how can i set the selected variable shown on the listbox to my textbox?

I've tried

Code:

textBox1.Text(listBox1.Item.Selected)

but it gives me an error on ".Text" :S
