Gets or sets the character to be displayed in substitute for user input.
public:
property char PasswordChar { char get(); void set(char value); };public char PasswordChar { get; set; }member this.PasswordChar : char with get, setPublic Property PasswordChar As CharProperty Value
The Char value used as the password character.
Exceptions
The character specified when setting this property is not a valid password character, as determined by the IsValidPasswordChar(Char) method of the MaskedTextProvider class.
The password character specified is the same as the current prompt character, PromptChar. The two are required to be different.
Remarks
For sensitive user input, it is common practice to conceal the actual information entered by the user. If the PasswordChar property is set to a non-null character, MaskedTextBox will display this character for all input into the control. Setting this property to null will disable this functionality.
If you want to use the operating system supplied password character, which is defined in COMCTL32.dll, use the UseSystemPasswordChar property instead. If both the PasswordChar and UseSystemPasswordChar properties are activated, the latter takes precedence.
Important
As a security consideration, the MaskedTextBox control disables cut and copy operations on password-protected strings.
