构造函数| 名称 | 说明 | |
|---|---|---|
 | XsFileStream | Initializes a new instance of the FileStream class with the specified path, creation mode, read/write and sharing permission, the access other FileStreams can have to the same file, the buffer size, and additional file options. |
属性
方法| 名称 | 说明 | |
|---|---|---|
 | CreateFileStream | Create a XsFileStream object on Windows and a normal FileStream object on other OS-es |
| 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).) |

 | 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。) |
