语法XsWin32FileStream 类型公开以下成员。
属性| 名称 | 说明 | |
|---|---|---|
 | FileName | The name of the file opened in the stream. (继承自 XsFileStream。) |
| Length | Gets the length in bytes of the stream. (重写 Length.) |
方法| 名称 | 说明 | |
|---|---|---|
 | Flush | Clears buffers for this stream and causes any buffered data to be written to the file. (重写 Flush.) |
| Flush(Boolean) | Clears buffers for this stream and causes any buffered data to be written to the file, and also clears all intermediate file buffers. (重写 Flush(Boolean).) |
| Lock | Prevents other processes from reading from or writing to the FileStream. (重写 Lock(Int64, Int64).) |
| Read | Reads a block of bytes from the stream and writes the data in a given buffer. (重写 Read(Byte, Int32, Int32).) |
| Seek | Sets the current position of this stream to the given value. (重写 Seek(Int64, SeekOrigin).) |
| SetLength | Sets the length of this stream to the given value. (重写 SetLength(Int64).) |
| Unlock | Allows access by other processes to all or part of a file that was previously locked. (重写 Unlock(Int64, Int64).) |
| Write | Writes a block of bytes to the file stream. (重写 Write(Byte, Int32, Int32).) |
| WriteByte | Writes a byte to the current position in the file stream. (重写 WriteByte(Byte).) |
扩展方法| 名称 | 说明 | |
|---|---|---|
 | SafeLock | Locks a region in a stream. Contains TRY CATCH mechanism. (由 FileStreamExensions 定义。) |
| SafeRead(Byte) | 已重载。 Read data from a stream. Assumes that the whole buffer must be read. Reads from current location. (由 FileStreamExensions 定义。) |
| SafeRead(Byte, Int32) | 已重载。 Read data from a stream. Contains TRY CATCH mechanism. Reads from current location. (由 FileStreamExensions 定义。) |
| SafeRead(Byte, Int32, Int32) | 已重载。 Read data from a stream. Contains TRY CATCH mechanism. Reads from current location. (由 FileStreamExensions 定义。) |
| SafeReadAt(Int64, Byte) | 已重载。 Read data at a location in the file. Makes sure that file locations are >= 0. Assumes whole buffer must be read. (由 FileStreamExensions 定义。) |
| SafeReadAt(Int64, Byte, Int32) | 已重载。 Read data at a location in the file. Makes sure that file locations are >= 0 (由 FileStreamExensions 定义。) |
| SafeSetLength | Sets the length of a stream. Contains TRY CATCH mechanism. (由 FileStreamExensions 定义。) |
| SafeSetPos | Sets the location of a stream. Contains TRY CATCH mechanism. . (由 FileStreamExensions 定义。) |
| SafeUnlock | Unlocks a region in a stream. Contains TRY CATCH mechanism. (由 FileStreamExensions 定义。) |
| SafeWrite(Byte) | 已重载。 Write data to a stream. Contains TRY CATCH mechanism. Writes to the current location. Assumes the whole buffer must be written. (由 FileStreamExensions 定义。) |
| SafeWrite(Byte, Int32) | 已重载。 Write data to a stream. Contains TRY CATCH mechanism. Writes to the current location. (由 FileStreamExensions 定义。) |
| SafeWriteAt(Int64, Byte) | 已重载。 Write data at a location in the file. Makes sure that file locations are >= 0. Assumes whole buffer must be written. (由 FileStreamExensions 定义。) |
| SafeWriteAt(Int64, Byte, Int32) | 已重载。 Write data at a location in the file. Makes sure that file locations are >= 0. (由 FileStreamExensions 定义。) |
| SafeWriteByte | Write data to a stream. Contains TRY CATCH mechanism. Writes to the current location. (由 FileStreamExensions 定义。) |
备注The class bypasses some of the default methods in the FileStraem class and directly uses calls to OS functions to make
sure that changes made by other users are visible and not hidden because of caching in the .Net FileStream class.
