The earliest use of the queue to hold data, the time node for a one-time read and FTP transmission, but the queue data is too slow, so reuse the memory stream to solve the performance of the data, on the other hand, the data for seamless FTP upload.
1, first set up a memory stream MemoryStream, and build its StreamWriter
MemoryStream data_stream = new MemoryStream ();
StreamWriter data_writer = new Stream
Java The buffer stream itself has no IO function, but adds buffering to the other streams to improve efficiency, such as loading a wrapper over another stream . When the file or other target frequently read or write or operate inefficient, poor performance. This allows for more efficient reading and writing of information using buffered streams. Because the buffered str
Stream ends with a byte stream, and reader and writer end up with a character streamThe difference between the two is read and write, one is read by Byte, and the other is by character. Operation ByteReading and writing a file requires that the content be processed in rows, such as comparing specific characters, and a character stream is typically selected when p
ADODB. Stream is a stream object of ADO. It provides access to binary data or text streams to implement stream read, write, and management operations.

In the program, a character equals two bytes, and a Chinese character occupies two bytes (General Limited interview will ask: A char can save a Chinese character, the answer i
Java.io Package: Provides system input and output via data flow, serialization, and file system
Below to understand what is IO stream?
The IO stream is used to process data transfer between devices. The Java operation of data is divided into the input stream and the output stream by the way of flow, divided into byte
