IdnMapping.UseStd3AsciiRules Property

Note: This property is new in the .NET Framework version 2.0.

Gets or sets a value indicating whether standard or nonstandard naming conventions are used in operations performed by members of the current IdnMapping object.

Namespace: System.Globalization
Assembly: mscorlib (in mscorlib.dll)

public bool UseStd3AsciiRules { get; set; }
/** @property */
public boolean get_UseStd3AsciiRules ()

/** @property */
public void set_UseStd3AsciiRules (boolean value)

public function get UseStd3AsciiRules () : boolean

public function set UseStd3AsciiRules (value : boolean)

Property Value

true if nonstandard naming conventions are used in operations; otherwise, false.

Domain names that follow standard naming rules consist of characters in the US-ASCII character range. The characters are the letters A through Z, the digits 0 through 9, the hyphen (-) character, and the period (.) character. The case of the domain name is not significant.

For more information, see the RFC 1122 standard, "Requirements for Internet Hosts – Communication Layers," at Request for Comments (RFC).

NoteNote

The IdnMapping class prohibits the use of the nondisplayable characters U+0000 through U+001F and U+007F in domain name labels regardless of the setting of the UseStd3AsciiRules property. This prohibition reduces the risk of security attacks such as name spoofing.
