Class OdfCrc32Stream

Namespace

OdfKit.Core

Assembly

OdfKit.dll

Wraps a stream and computes a running CRC-32 checksum while bytes are read or written. 包裝資料流，並在讀取或寫入位元組時即時計算累積的 CRC-32 校驗碼。

Constructors

OdfCrc32Stream(Stream)

Short overload of OdfCrc32Stream that accepts underlyingStream; remaining optional parameters use defaults and forward to the full overload. 便利多載：提供 underlyingStream；其餘可選參數使用預設值並轉呼叫最長 OdfCrc32Stream 多載。

public OdfCrc32Stream(Stream underlyingStream)

Parameters

underlyingStream Stream

OdfCrc32Stream(Stream, uint?)

Initializes a new instance of the OdfCrc32Stream class. 初始化 OdfCrc32Stream 類別的新執行個體。

public OdfCrc32Stream(Stream underlyingStream, uint? expectedCrc)

Parameters

underlyingStream Stream

The stream to wrap. / 要包裝的資料流。

expectedCrc uint?

The optional expected CRC-32 value to verify at end of stream. / 選用的預期 CRC-32 值，會在讀取至結尾時驗證。
