MaskedTextProvider.PasswordChar Property

Gets or sets the character to be substituted for the actual input characters.

Namespace:  System.ComponentModel
Assembly:  System (in System.dll)

public char PasswordChar { get; set; }

Property Value

Type: System.Char
The Char value used as the password character.


The password character specified when setting this property is the same as the current prompt character, PromptChar. The two are required to be different.


The character specified when setting this property is not a valid password character, as determined by the IsValidPasswordChar method.

For sensitive user input, it is common practice to conceal the actual information entered by the user during output operations. If the PasswordChar property is set to a non-null character, output methods such as ToDisplayString and ToString will obscure the input characters with the specified password character. Setting this property to null will disable password protection functionality.
