Question

I want show text in textbox in 2 colors, for example 1 line red 2 blue, if I use name.ForeColor = Color.Red; all text change color, but I want that will change only 1 line color.

Answer 1

Use a RichTextBox for that, here is an extension method by Nathan Baulch

public static class RichTextBoxExtensions
{
    public static void AppendText(this RichTextBox box, string text, Color color)
    {
        box.SelectionStart = box.TextLength;
        box.SelectionLength = 0;

        box.SelectionColor = color;
        box.AppendText(text);
        box.SelectionColor = box.ForeColor;
    }
}
