C# Textbox using void to change font style

Question

I'm a beginner in programming and trying to teach myself at home using the Internet and such to practice on tasks and I'm trying to create a very simple word processor. With the font editing (Bold, underline, italic, etc.) I found using

C#

this.Font = new Font(this.Font, FontStyle.Underline);

changes the entire applications fonts to that single font style. I want the user to be able to have Bold and underlined at the same time so I tried using booleans.
For example:

C#

static bool bold = false;
static bool underlined = false;
private void label3_Click(object sender, EventArgs e)
{
            bold = true;
            fonts();
        }
        private void label2_Click(object sender, EventArgs e)
        {
            underlined = true;
            fonts();
        }
        void fonts()
        {
            if ((bold) && (underlined))
            {
                textBox1.Font = new Font(textBox1.Font, FontStyle.Bold & FontStyle.Underline);
                underlined = false;
                bold = false;
            }
        }

but nothing happens when the bold and underlined label are clicked when it should notice both bool's are true and therefore set textBox1.Font to bold and underlined, right?

But nothing happens. Why? :D
Remember I'm very new to this and any basic and easy to understand explanations and tips would be so appreciated =)

What do you try to achieve by "FontStyle.Bold & FontStyle.Underline"? :-)

Solution 1

FontStyle is enum and therefore you can set multiple styles by |, like this:

C#

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

Most likely, that was the problem. My 5. OP is recommended to understand bitwise operations, and Boolean as well.

1. Assuming that you are now using a TextBox: all changes to any TextBox Font property will set the font-styles, size, etc., for ALL content. If that's what you want, you may want to skip the rest of this comment :)

... edit : removed incorrect content: properties of a Font of a Control, like a TextBox, like 'Bold are read-only ...

a. looking at your specific code: why are you bothering to reset 'bold and 'underlined booleans to false ?

b. you already have good answers here to show you how to combine style flags using logical-Or, so that's taken care of

c. if you want to define FontStyles in advance and re-use them: it's pretty easy:

FontStyle fs1 = new FontStyle();
fs1 = FontStyle.Bold;

textBox1.Font = new Font(textBox1.Font, fs1);

FontStyle fs2 = new FontStyle();
fs2 = FontStyle.Underline;

textBox1.Font = new Font(textBox1.Font, fs1 | fs2);

2. But, assuming that you want to make a text-editor where some of the Text can be underlined, or bolded, but other parts of the Text can be plain, or in different font-sizes, or even colors:

You need to change to using a RichTextBox.

Here on CP are several excellent examples of extended RichTextBox based editors: suggest you search for them, and study them.
