Question

private void LoadKeys(Dictionary<string,List<string>> dictionary, string FileName)
        {
           string line = System.String.Empty;
           using (StreamReader sr = new StreamReader(keywords))
           {
            while ((line = sr.ReadLine()) != null)
            {
                string[] tokens = line.Split(',');
                dictionary.Add(tokens[0], tokens.Skip(1).ToList());
                richTextBox2.AppendText("Url: " + tokens[0] + " --- " + "Localy KeyWord: " + tokens[1]+Environment.NewLine);
                ColorText(richTextBox2, Color.Red);
            }
           } 
        }

And the function ColorText:

public void ColorText(RichTextBox box, Color color)
        {
            box.SelectionStart = box.TextLength; box.SelectionLength = 0;
            box.SelectionColor = color;
            box.SelectionColor = box.ForeColor;
        } 

But it didnt color anything in Red. Nothing changed.
I want to be able to color in Red for exmaple only the tokens[0] and in Green tokens[1] for example.

How can i do it ?

public void ColorText(RichTextBox box, Color color)
        {
            box.Select(start, 5);
            box.SelectionColor = color;
        }
