How to enter a special character as a password character in C#

How do I enter a unicode character (it needs to be the equivalent of ascii character 254, a solid square centered box) as the password character in a textbox?

I need to do this in code, 开发者_运维百科for example textbox.passwordchar = ????????

Thanks,

The same way you enter any other character.
C# source files can contain Unicode characters in identifiers and strings.

You can also use the escape sequence "\uxxxx" to use a Unicode character by (hex) codepoint.

Use the TestBox.PasswordChar property. Assuming you want UNICODE character BLACK SQUARE (U+25A0), either do:

yourTextBox.PasswordChar = '■';

Or:

yourTextBox.PasswordChar = '\u25a0';

---

textBox_Name.PasswordChar='■';

When you want to use any of the unicode char simply Press ALT & then ascii value of that key while pressing ALT key

e.g.

■ = ALT+254

♪ = ALT+269

A = ALT+65

a = ALT+97

NOTE: numeric keys must be pressed from NumPad

tb.PasswordChar = (char)254;

I believe you should be able to just assign a constant Unicode character, as described in this MSDN article...

this.tePassword.Properties.PasswordChar = (char)254; results in a character that looks similar to a b - it's definitely not ascii 254.
