MaskedTextProvider Constructor (String, CultureInfo, Boolean, Char, Char, Boolean)

Initializes a new instance of the MaskedTextProvider class using the specified mask, culture, prompt usage value, prompt character, password character, and ASCII restriction value.

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

public MaskedTextProvider(
	string mask,
	CultureInfo culture,
	bool allowPromptAsInput,
	char promptChar,
	char passwordChar,
	bool restrictToAscii


Type: System.String

A String that represents the input mask.

Type: System.Globalization.CultureInfo

A CultureInfo that is used to set region-sensitive separator characters.

Type: System.Boolean

A Boolean value that specifies whether the prompt character should be allowed as a valid input character.

Type: System.Char

A Char that will be displayed as a placeholder for user input.

Type: System.Char

A Char that will be displayed for characters entered into a password string.

Type: System.Boolean

true to restrict input to ASCII-compatible characters; otherwise false to allow the entire Unicode set.


The mask parameter is null or Empty.


The mask contains one or more non-printable characters.

This constructor represents the most general overloaded form. The mask parameter must conform to the masking language defined by the MaskedTextProvider class, which is detailed in the MaskedTextBox.Mask property of the MaskedTextBox class.

Because neutral cultures cannot be queried for culture-specific information, the MaskedTextProvider constructor will use the GetCultures method to search for the first non-neutral culture to use to determine the proper separator characters.
