Note

This functionality is only available to mobile operator apps and Windows Store app given privileged access by mobile network operators, mobile broadband adapter IHV, or OEM. For more information, see Mobile Broadband: device apps.

Note

Note that this class and its methods are supported for the maintenance of legacy desktop apps that used it in earlier versions of Windows; and if you do use this class, you must specify the Windows.Devices.Sms.LegacySmsApiContract in your app's manifest. Do not use this class if you are developing new apps for Windows 10. Instead, use the members of this namespace that do not require the Windows.Devices.Sms.LegacySmsApiContract.

PartReferenceId PartReferenceId PartReferenceId PartReferenceId

Indicates a reference value that can be used if the message is part of a multi-part message. If this message belongs to a multi-part message, the PartNumber value can be used to reconstruct the full original message, and each part of that message will have the same value for PartReferenceId.

public : unsigned short PartReferenceId { get; }public uint PartReferenceId { get; }Public ReadOnly Property PartReferenceId As uint// You can use this property in JavaScript.
Value
unsigned short uint uint uint

An unsigned integer determined by the sending network; it cannot be manipulated through this interface. If the network has its own policy on the lifetime of a multi-part message, this reference number might not be valid indefinitely.

Methods

FromBinaryData(SmsDataFormat, Byte[]) FromBinaryData(SmsDataFormat, Byte[]) FromBinaryData(SmsDataFormat, Byte[]) FromBinaryData(SmsDataFormat, Byte[])

Decodes a binary message and places the results in a new instance of a text message. This method represents the binary message as a reference to a buffer of bytes and a selection of how the buffer is encoded. Therefore, it can be used when the message did not originate directly from the device or as an instance of an SmsBinaryMessage class.

public : static SmsTextMessage FromBinaryData(SmsDataFormat format, Byte[] value)public static SmsTextMessage FromBinaryData(SmsDataFormat format, Byte[] value)Public Static Function FromBinaryData(format As SmsDataFormat, value As Byte[]) As SmsTextMessage// You can use this method in JavaScript.
Parameters
format
SmsDataFormat SmsDataFormat SmsDataFormat SmsDataFormat

An SmsDataFormat enumerated value that identifies the format of a particular protocol description unit (PDU) buffer.

value
Byte[] Byte[] Byte[] Byte[]

An array of bytes containing the binary data to decode.

Returns

A new SmsTextMessage object if the decoding was successful.
