C# 클래스 Redzen.IO.NonClosingStreamWrapper

Wraps a stream and prevents calls to Close() and Dispose() from being made on it. This is useful for other classes that wrap a stream but have no option to leave the wrapped stream open upon Dispose(), e.g. CryptoStream and BinaryWriter. Note. Later versions of the .NET framework have added a 'leaveOpen' option to some classes. Check before using this class.

BeginRead ( byte buffer, int offset, int count, AsyncCallback callback, object state ) : IAsyncResult	Begins an asynchronous read operation.

Close ( ) : void	This method is not proxied to the underlying stream; instead, the wrapper is marked as unusable for other (non-close/Dispose) operations. The underlying stream is flushed if the wrapper wasn't closed before this call.

메소드 상세

BeginRead() 공개 메소드

Begins an asynchronous read operation.

public BeginRead ( byte buffer, int offset, int count, AsyncCallback callback, object state ) : IAsyncResult
buffer	byte	The buffer to read the data into.
offset	int	The byte offset in buffer at which to begin writing data read from the stream.
count	int	The maximum number of bytes to read.
callback	AsyncCallback	An optional asynchronous callback, to be called when the read is complete.
state	object	A user-provided object that distinguishes this particular asynchronous read request from other requests.
리턴	IAsyncResult

BeginWrite() 공개 메소드

Begins an asynchronous write operation.

public BeginWrite ( byte buffer, int offset, int count, AsyncCallback callback, object state ) : IAsyncResult
buffer	byte	The buffer to write data from.
offset	int	The byte offset in buffer from which to begin writing.
count	int	The maximum number of bytes to write.
callback	AsyncCallback	An optional asynchronous callback, to be called when the write is complete.
state	object	A user-provided object that distinguishes this particular asynchronous write request from other requests.
리턴	IAsyncResult

Close() 공개 메소드

This method is not proxied to the underlying stream; instead, the wrapper is marked as unusable for other (non-close/Dispose) operations. The underlying stream is flushed if the wrapper wasn't closed before this call.

public Close ( ) : void
리턴	void

CreateObjRef() 공개 메소드

Not implemented. Throws NotSupportedException.

public CreateObjRef ( Type requestedType ) : ObjRef
requestedType	System.Type	The Type of the object that the new ObjRef will reference.
리턴	System.Runtime.Remoting.ObjRef

EndRead() 공개 메소드

Waits for the pending asynchronous read to complete.

public EndRead ( IAsyncResult asyncResult ) : int
asyncResult	IAsyncResult	The reference to the pending asynchronous request to finish.
리턴	int

EndWrite() 공개 메소드

Ends an asynchronous write operation.

public EndWrite ( IAsyncResult asyncResult ) : void
asyncResult	IAsyncResult	A reference to the outstanding asynchronous I/O request.
리턴	void

Flush() 공개 메소드

Flushes the underlying stream.

public Flush ( ) : void
리턴	void

InitializeLifetimeService() 공개 메소드

Not implemented. Throws NotSupportedException.

public InitializeLifetimeService ( ) : object

NonClosingStreamWrapper() 공개 메소드

Construct with the provided stream to be wrapped.

public NonClosingStreamWrapper ( Stream stream ) : System
stream	Stream	The stream to be wrapped.
리턴	System

Read() 공개 메소드

Reads a sequence of bytes from the underlying stream and advances the position within the stream by the number of bytes read.

public Read ( byte buffer, int offset, int count ) : int
buffer	byte	An array of bytes. When this method returns, the buffer contains /// the specified byte array with the values between offset and (offset + count- 1) replaced /// by the bytes read from the underlying source.
offset	int	The zero-based byte offset in buffer at which to begin storing the data /// read from the underlying stream.
count	int	The maximum number of bytes to be read from the underlying stream.
리턴	int
