如何更改文字的字体样式

Question

How can I change the Font Style (regular, bold, etc) ?

So far what I have is this:

if (listBox1.SelectedIndex == 3)
{
   if (textBox1.Text == "regular")
   {
     //FontStyle regular = new FontStyle   !!!wrong one!!!
   }
}

So what i need is that when I'd type "regular" in the textbox, the font style will change to regular. How do I do that?

Answer 1

You need to set the Control.FontWeight property

if (listBox1.SelectedIndex == 3)
{
      if (textBox1.Text == "regular")
      {         
          TextBox1.FontWeight = FontWeights.Regular;
      }
}

Answer 2

您是否正在寻找这样的东西：

textBox1.Font = new Font(textBox1.Font, FontStyle.Bold);

Answer 3

You need to create a new Font and apply it to your text box:

textBox1.Font = new Font(FontFamily.GenericSansSerif, 12.0F, FontStyle.Normal);

This will create one with a new family etc. You can read the size and family from the existing Font object to preserve those.

textBox1.Font = new Font(textBox1.Font, FontStyle.Normal);
