If you're going to select the text file from the OpenFileDialog then the code will be as follows: private void button1_Click(object sender EventArgs e) { OpenFileDialog loadaccounts = new OpenFileDialog(); loadaccounts.Filter = Text Files (*.txt)|*.txt; loadaccounts.Title = Load Accounts; DialogResult dr = loadaccounts.ShowDialog(); if (dr == DialogResult.OK) { string filePath = loadaccounts.FileName; string[] lines = System.IO.File.ReadAllLines(filePath); // as we don't know how many lines there are need to allow for all possibilities textBox1.Clear(); textBox2.Clear(); textBox3.Clear(); if (lines.Length >= 1) textBox1.Text = lines[0]; if (lines.Length >= 2) textBox2.Text = lines[1]; if (lines.Length >= 3) textBox3.Text = lines[2]; } }

Try: private void button1_Click(object sender EventArgs e) { string filePath = @c:\myfiles	xt.txt; // or whatever full path of file is string[] lines = System.IO.File.ReadAllLines(filePath); textBox1.Text = lines[0]; textBox2.Text = lines[1]; textBox3.Text = lines[2]; }

I think the following shows another possiblity. I do no tthink there is amny advantage of wone over the other. Note taht I save and restore the filename to and from a property. OpenFileDialog ofd = new OpenFileDialog (); ofd.FileName = Properties. Settings .Default.LastFilenameSetting; ofd.DefaultExt = txt ; ofd.Filter = Text files (*.txt)|*.txt|All files (*.*)|*.* ; DialogResult dr = ofd.ShowDialog(); if (dr != DialogResult .OK) return ; Properties. Settings .Default.LastFilenameSetting = ofd.FileName; Properties. Settings .Default.Save(); TextBox [] tba = new TextBox [3]; tba[0] = textBox1; tba[1] = textBox2; tba[2] = textBox3; using ( StreamReader sr = new StreamReader (ofd.FileName)) { for ( int i = 0; i tba[i].Text = sr.ReadLine(); }

Except my code does not clear out he textboxes first. You can add that if needed.

that's why I'm a fan of vulpes! Thank you so much mate. your code works. but how can I do it with OpenFileDialog... because I want to load any .txt file from pc. I wrote: OpenFileDialog loadaccounts = new OpenFileDialog(); loadaccounts.Filter = Text Files (*.txt)|*.txt; loadaccounts.Title = Load Accounts; StreamReader sr = new StreamReader(loadaccounts.FileName); sr.Close(); string filePath = sr.ReadToEnd(); string[] lines = File.ReadAllLines(filePath); textBox1.Text = lines[0]; textBox2.Text = lines[1]; textBox3.Text = lines[2]; but this doesn't work..
