I was able to get the ComboBox to load a list of files from a directory.
but, now i am trying to get the contents of that file output to a TextBox or richTextBox.

I am able to use this to output to another ComboBox(however, this is not what i need...):
//code for codebox to codeBox output

string[] files = System.IO.Directory.GetFiles(@"c:\scripts");

        string[] lineOfContents = File.ReadAllLines(comboBox1.Text);
        foreach (var line in lineOfContents)
            string[] tokens = line.Split(',');
            //end of codebox to codebox output.

However, I can't get the entire file to go to a Textbox.
When i use <this.richTextBox1.Text = comboBox2.Text;>
it only pulls the selected line of th text from the combobox and doesnt pull all lines of the .TXT as its split into seperate lines.

Summary: I cant seem to to pull all Lines of text from the textfile listed within the combobox into a Richtextbox by using the combobox to retrieve the list of files first.

  • am I making this too complicated and just missing something very simple??

I can use radio buttons to push the contents of the file to the RichTextBox.... something about loading from combobox to TextBox is not working.

Thank you in Advance!!!


It looks like you need to use the AppendText method of the TextBox class:

        foreach(string line in File.ReadAllLines(comboBox1.Text))
