Parameters

Type	Name	Description

Fields

InvalidCharacters

Regular expression that matches all characters which can't be used in an SDP token.

Declaration

public const string InvalidCharacters = "[^A-Za-z0-9!#$%&'*+-.^_`{|}~]"

Field Value

Type	Description
String

Properties

AllowEmpty

Allow empty tokens, that is a string property which is null or an empty string. This is not valid in the RFC, but can be allowed as a property value to represent a default value generated at runtime by the implementation instead of being provided by the user.

This is typically used as an argument to Validate(String, Boolean).

Declaration

public bool AllowEmpty { get; }

Property Value

Type	Description
Boolean	true to allow the property to be null or empty.

Methods

Validate(String, Boolean)

Validate an SDP token name against the list of allowed characters:

• Symbols [!#$%'*+-.^_`{|}~&]
• Alphanumerical characters [A-Za-z0-9]

If the validation fails, the method throws an exception.

Declaration

public static void Validate(string name, bool allowEmpty = true)

Parameters

Type	Name	Description
String	name	The token name to validate.
Boolean	allowEmpty	true to allow the property to be null or empty without raising an exception.
