ReserveAndAppend(IList<ArraySegment<Byte>>, SequenceNumber, SequenceNumber, RecordAppendOptions, ReservationCollection, Int64[])

自动生成一个预留，并向序列中追加一条记录。无法继承此方法。

public:
 virtual System::IO::Log::SequenceNumber ReserveAndAppend(System::Collections::Generic::IList<ArraySegment<System::Byte>> ^ data, System::IO::Log::SequenceNumber nextUndoRecord, System::IO::Log::SequenceNumber previousRecord, System::IO::Log::RecordAppendOptions recordAppendOptions, System::IO::Log::ReservationCollection ^ reservationCollection, ... cli::array <long> ^ reservations);

public System.IO.Log.SequenceNumber ReserveAndAppend (System.Collections.Generic.IList<ArraySegment<byte>> data, System.IO.Log.SequenceNumber nextUndoRecord, System.IO.Log.SequenceNumber previousRecord, System.IO.Log.RecordAppendOptions recordAppendOptions, System.IO.Log.ReservationCollection reservationCollection, params long[] reservations);

abstract member ReserveAndAppend : System.Collections.Generic.IList<ArraySegment<byte>> * System.IO.Log.SequenceNumber * System.IO.Log.SequenceNumber * System.IO.Log.RecordAppendOptions * System.IO.Log.ReservationCollection * int64[] -> System.IO.Log.SequenceNumber
override this.ReserveAndAppend : System.Collections.Generic.IList<ArraySegment<byte>> * System.IO.Log.SequenceNumber * System.IO.Log.SequenceNumber * System.IO.Log.RecordAppendOptions * System.IO.Log.ReservationCollection * int64[] -> System.IO.Log.SequenceNumber

Public Function ReserveAndAppend (data As IList(Of ArraySegment(Of Byte)), nextUndoRecord As SequenceNumber, previousRecord As SequenceNumber, recordAppendOptions As RecordAppendOptions, reservationCollection As ReservationCollection, ParamArray reservations As Long()) As SequenceNumber

参数

data: IList<ArraySegment<Byte>>

将连接在一起并以记录形式追加的字节数组段的列表。

nextUndoRecord: SequenceNumber

用户指定顺序中下一条记录的序列号。

previousRecord: SequenceNumber

“上一个”顺序中下一条记录的序列号。

recordAppendOptions: RecordAppendOptions

RecordAppendOptions 的一个有效值，用于指定应如何写入数据。

reservationCollection: ReservationCollection

要在其中生成预留的预留集合。

reservations: Int64[]

要生成的预留（以字节为单位）。

SequenceNumber

追加的日志记录的序列号。

实现

ReserveAndAppend(IList<ArraySegment<Byte>>, SequenceNumber, SequenceNumber, RecordAppendOptions, ReservationCollection, Int64[])

例外

ArgumentNullException

一个或多个参数为 null。

ArgumentOutOfRangeException

一个或多个自变量超出范围。

ArgumentException

reservations 不是由此记录序列创建的。

NotSupportedException

由于记录序列是通过只读访问权限打开的，因此无法执行该操作。

IOException

由于出现意外的 I/O 异常，因此无法执行该请求。

ObjectDisposedException

该方法是在序列已释放之后调用的。

OutOfMemoryException

没有足够的内存来继续执行该程序。

SequenceFullException

记录序列已满。

注解

包含在 data 参数中的数据将连接成单个字节数组，以便以记录形式追加。但在读取记录时，无法将数据重新拆分为数组段。

在原子操作中，使用记录追加操作将指定的预留添加到所提供的预留集合。如果追加失败，将不保留任何空间。

通常，此方法可以在写入记录之前完成。若要确保记录已写入，请使用 ForceFlush 参数指定 recordAppendOptions 标志，或者调用 Flush 方法。
