Color different parts of a RichTextBox string

Question

I\'m trying to color parts of a string to be appended to a RichTextBox. I have a string built from different strings.

string temp = \"[\" + DateTime.Now.ToSh         


        

Answer 1

This is the modified version that I put in my code (I'm using .Net 4.5) but I think it should work on 4.0 too.

public void AppendText(string text, Color color, bool addNewLine = false)
{
        box.SuspendLayout();
        box.SelectionColor = color;
        box.AppendText(addNewLine
            ? $"{text}{Environment.NewLine}"
            : text);
        box.ScrollToCaret();
        box.ResumeLayout();
}

Differences with original one:

• possibility to add text to a new line or simply append it
• no need to change selection, it works the same
• inserted ScrollToCaret to force autoscroll
• added suspend/resume layout calls
