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

You need to use a RichTextBox.

You can then change the textcolor by selecting text and changing the selection color or font.

richTextBox1.SelectionFont = new Font("Verdana", 12, FontStyle.Bold);
richTextBox1.SelectionColor = Color.Red;
