Question

I am new to c# and I have a question that probably has a very simple solution. I want to import a .txt file for viewing into a textbox and maintain the format of the original file (all the correct spacings). Is this possible? I am using the following code to open the .txt files when the user clicks a button and have the files displayed. Again, I am very new to programming and any help would be greatly appreciated.

OpenFileDialog ofd = new OpenFileDialog();

ofd.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*";

if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
    StreamReader sr = File.OpenText(ofd.FileName);
    string s = sr.ReadLine();
    StringBuilder sb = new StringBuilder();
    while (s != null)
    {
        sb.Append(s);
        s = sr.ReadLine();
    }
    sr.Close();
    textBox1.Text = sb.ToString();
}

Answer 1

I believe that you should use

sb.AppendLine(); 

instead of sb.Append();

now, you could (should) also use ReadToEnd() , as suggested by David Heffernan.

using(StreamReader sr = File.OpenText(ofd.FileName)) {
   textBox1.Text = sr.ReadToEnd();
}
