encoding.StreamWriter classImplements a TextWriter that writes characters to a stream in a specific encodingTextReader classRepresents a reader that can read a series of contiguous characters.TextWriter classRepresents a writer that can write an ordered series of characters. The class is an abstract class.BinaryReader classReads the primitive data type as a binary value with a specific encoding. You can think of BinaryReader as an extension to Stream
C # 's FileStream class provides the most primitive byte-level file read and write functionality, but we are accustomed to manipulating strings, so the StreamWriter and StreamReader classes enhance the FileStream, which lets us manipulate files at the string level, But sometimes we still need to manipulate the file at the byte level, but not a byte-by-bit operation, usually 2, 4, or 8 bytes, which has the BinaryWriter and BinaryReader classes, which c
He looked at binarywriter/binaryreader and tried it. He was impressed by the fact that he had been studying it for several days. By the way, he made a summary: Concept of three-tier architecture User Interface presentation layer (USL/UI) business logic layer (BLL) data access layer (DAL) Role of each layer 1. Data access layer: it is the operation layer for raw data (in the form of database or text files). It provides data services for the business lo

the stream in a specific encoding. TextreaderClass The reader that can read the continuous character series. TextwriterClass Indicates that an ordered character series writer can be compiled. This class is an abstract class. BinaryreaderClass The base metadata type is read as a binary value using a specific encoding. Binarywriter Writes the primitive type to the stream in binary format, and supports writing strings with specific encoding. The binarywriter and

object is then used to get other more convenient objects, such as BinaryReader objects, binarywrite objects, to prepare for further communication with the other. 3. Each get a new TcpClient object, create a thread that corresponds to the customer, and the threads communicate with the corresponding customer. 4. Determine whether to close the connection to the customer based on the information sent. Using System; Using System.Collections.Gen
Grasp the Stream in VB. NET (2) Flexible and diverse IO OperationSometimes conversion between data and byte arrays is cumbersome. To avoid these boring conversions and simplified code, it is wise to use streamreader/streamwrite and binaryreader/binarywriter. Streamreader and streamwrite are derived from the textreader and textwriter classes respectively, and are automatically converted to Byte encoding. Binaryrea
