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
Class Number: VIP17 student Name: Xiao Wu Course name: javaseData type FlowDataOutputStream is the data type output stream, which can write the basic data type directly into the file;DataInputStream is a data type input transmission, it can be the basic data type directly read to the program, the first to write out what order, read in the order to read in accordance with the sequence of reading, sequential reading counter will be garbled or incorrect
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
One, file streamThe FileStream class is primarily used to read and write disk files. Often used to store data or read configuration files to disk.Read file:Copy Code//file stream: ReadFileStream FileStream = File.Open (@"D:\test.txt", FileMode.Open);//initializing a file streambyte[] Array =New byte[Filestream.length];//Initializes a byte array that is used to stage the bytes read toFileStream.Read (Array,0, array.

The dual stream uses a high bitrate code stream for local HD storage, such as QCIF/CIF/D1 encoding, where low bitrate streams are used for network transmission, such as QCIF/CIF encoding, while taking into account local storage and remote network transmission. Dual-stream can realize local transmission and remote transmission of two different bandwidth code flow
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.
There are the following methods:Cancel MethodThe usage is as follows:Object. CancelDescription: cancels the call of an asynchronous execute or open method suspended for execution.Close MethodThe usage is as follow
Stream Data Stream in Java 8 and java8Stream data StreamFilter repeated Elements
The Stream interface supports the distinct method, which returns a Stream of elements (implemented based on the hashCode and equals methods of the elements generated by the Stream.
For example,

serializing and deserializing streamsThe flow of operations used to read an object from a stream ObjectInputStream called a deserialization streamThe flow of operations used to write objects to the stream ObjectOutputStream is called a serialized stream (the object is saved to a file)L Features: For manipulating objects . You can write an object to a file, or you
[JavaSE] I/O Stream (pipeline stream) and javaseio Stream pipeline
Previously, I/O streams were used to require an intermediate array. Pipeline streams can be directly input to the output stream. They are generally used with multiple threads. When no data is read from the stream

The Java stream is processed into a character stream and a byte stream. A character stream processes a cell that is 2-byte Unicode characters, manipulating characters, character arrays, or strings, and a byte-stream processing unit of 1 bytes, manipulating bytes and byte arr
Java processing files in the class, stream at the end of the use of byte stream, reader and writer End is a character stream. The difference between the two is read and write, one is read by Byte, and the other is by character.
The bottom of the character stream is the byte stream
