Das ID-Formatschema des Anbieters.

Beispiel

Im folgenden Beispiel wird das ID-Formatschema eines Anbieters zurückgegeben, der Änderungseinheiten verwendet.

// Gets the ID format schema that is defined for this replica.
public override SyncIdFormatGroup IdFormats
{
    get 
    {
        SyncIdFormatGroup FormatGroup = new SyncIdFormatGroup();

        // Change unit IDs are an enumeration, so they are fixed length and contain one byte.
        FormatGroup.ChangeUnitIdFormat.IsVariableLength = false;
        FormatGroup.ChangeUnitIdFormat.Length = sizeof(byte);

        // Item IDs are of SyncGlobalId type, so they are fixed length and contain a ulong prefix plus a Guid.
        FormatGroup.ItemIdFormat.IsVariableLength = false;
        FormatGroup.ItemIdFormat.Length = (ushort)(sizeof(ulong) + Marshal.SizeOf(typeof(Guid)));

        // Replica IDs are the absolute path to the item store, so they are variable length with maximum
        // length equal to the maximum length of a path.
        FormatGroup.ReplicaIdFormat.IsVariableLength = true;
        FormatGroup.ReplicaIdFormat.Length = 260 * sizeof(char);

        return FormatGroup;
    }
}
