Exemplos
O exemplo a seguir retorna o esquema de formato de ID de um provedor que usa unidades de alteração.
// 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;
