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

Question

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, for example textbox.passwordchar = ????????

Thanks,

Answer 1

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.

Answer 2

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

yourTextBox.PasswordChar = '■';

Or:

yourTextBox.PasswordChar = '\u25a0';

Answer 3

tb.PasswordChar = (char)254;

Answer 4

我相信您应该能够只分配一个恒定的Unicode字符，如本MSDN文章中所述 ...

Answer 5

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

Answer 6

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

eg

■ = ALT+254

♪ = ALT+269

A = ALT+65

a = ALT+97

NOTE: numeric keys must be pressed from NumPad
