Which passwordchar shows a black dot (•) in a winforms textbox?

Question

Short question here:

In .Net 4.0 Winforms, how do I use the PasswordChar property of a Textbox to show a common black dot as a character? Is there perhaps some font I can use that has this as a character?

If I use 'UseSystemPasswordChar = true' it shows an asterisk (*).

Answer 1

You can use this one: ●

You can type it by holding Alt and typing 25CF.

Alternately, you may use this smaller one: •

You can type it by holding Alt and typing 2022.

Answer 2

Use the Unicode Character 'BLACK CIRCLE' (U+25CF) http://www.fileformat.info/info/unicode/char/25CF/index.htm

To copy and paste: ●

I was also wondering how to store it cleanly in a variable. As using

char c = '•';

is not very good practice (I guess). I found out the following way of storing it in a variable

char c = (char)0x2022;// or 0x25cf depending on the one you choose

or even cleaner

char c = '\u2022';// or "\u25cf"

same for strings

string s = "\u2022";
