How to 'align' text in RichTextBox C#?

问题

How do I align the text in a RichTextBox?

Basically, the RTB contains:

"--testing"

"--TESTING"

"TESTING--"

"testing--"

Which all have the same number of characters, but have different alignments. How can I align them properly? Im fairly new to C# and confused since it aligned properly in Java's TextArea.

Thank you!

You would have to change the font to a monospaced font, like Courier. This behavior you're showing is standard with most fonts, as not all characters are the same width.

回答2:

You want to use the RichTextBox.SelectionAlignment property.

For instance if you want the whole textbox centered, then you would do:

richTextBox1.SelectAll();
richTextBox1.SelectionAlignment = HorizontalAlignment.Center;

If you want only part of the textbox with a certain alignment, then use the RichTextBox.Select() routine to select the text, then set the SelectionAlignment property.

回答3:

richTextBox1.SelectAll();
richTextBox1.SelectionAlignment = HorizontalAlignment.Center;
richTextBox1.DeselectAll();

Unless it is very necessary for you to use a rich textbox, you can simply use a textbox and choose alignment as

textbox.TextAlign = HorizontalAlignment.Center;/*could be left, right or center*/
