GetPrimaryMultiLanguageStringAttributeById Method (id)

.NET Components for Mobility

Gets a String containing the value of the TextString service attribute with the specified ID, using the primary natural language.

Declaration Syntax

C#	Visual Basic

public string GetPrimaryMultiLanguageStringAttributeById(
	ServiceAttributeId id
)

Public Function GetPrimaryMultiLanguageStringAttributeById ( _
	id As ServiceAttributeId _
) As String

Parameters

id (ServiceAttributeId): The id of the service attribute to locate, as a ServiceAttributeId.

Return Value

[Missing <returns> documentation for "M:InTheHand.Net.Bluetooth.ServiceRecord.GetPrimaryMultiLanguageStringAttributeById(InTheHand.Net.Bluetooth.ServiceAttributeId)"]

Remarks

As noted in the documentation on this class, string are defined in an odd manner, and the multi-language strings defined in the base SDP specification are defined in a very very odd manner. The natural language and the string’s encoding are not included in the element, but instead are defined in a separate element, and the ID of the string attribute is modified. This pair is present for each natural language.

This method is provided to simplify accessing those strings, it will find the primary Language attribute and use it to find and decode the string. And if there is no primary Language attribute, which is the case in many of the records one sees on mobile phones, it will attempt the operation assuming the string is encoded in UTF-8 (or ASCII).

Examples

C#:

CopyC#

try {
  String sn = record.GetMultiLanguageStringAttributeById(UniversalAttributeId.ServiceName);
  Console.WriteLine("ServiceName: " + sn);
} catch (KeyNotFoundException) {
  Console.WriteLine("The record has no ServiceName Attribute.");
}

Exceptions

Exception	Condition
KeyNotFoundException	There is no attribute with the given Id in the record. Throws ArgumentException in NETCFv1
InvalidOperationException	The service element is not of type TextString.
DecoderFallbackException	If the value in the service element is not a valid string in the encoding specified in the given LanguageBaseItem.
