C# .NET multiline TextBox with same-width characters

Question

How can I make it so if you typed in a multiline TextBox:

abcde

ABCDE

So that the big E is directly below the little e. I want them to line up vertically if they are in the same row.

Answer 1

Can you just set the font on the textbox to a monospaced one?

In code, keeping the same size as the default font:

textBox.Font = new Font(FontFamily.GenericMonospace, textBox.Font.Size);

Or just change the Font property in the designer.

Answer 2

You can do this by using a fixed width font. Courier family fonts are often fixed width.

You can set the font in the property editor for the textbox control. For example, you can set the Font property to Courier New, 8.25pt.
