MaskedTextBox.UseSystemPasswordChar Property

Gets or sets a value indicating whether the operating system-supplied password character should be used.

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public bool UseSystemPasswordChar { get; set; }

Property Value

Type: System.Boolean
true if the system password should be used as the prompt character; otherwise, false. The default is false.

ExceptionCondition
InvalidOperationException

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

The UseSystemPasswordChar property determines whether user-supplied input should be displayed in the MaskedTextBox as multiple occurrences of a password character defined by the operating system. UseSystemPasswordChar functions similarly to the PasswordChar property, but instead of using a programmer-supplied character for the prompt, UseSystemPasswordChar uses a prompt defined by the operating system. This property has precedence over PasswordChar.

Important noteImportant Note:

As a security consideration, the MaskedTextBox control disables cut and copy operations on password-protected strings.
