Encoding Implementation & amp; gt; file and input/output & amp; gt; Stream

A Stream is a group of continuous data that has the beginning and end, and uses a cursor to indicate the current position.

The data contained in the Stream can be from the memory MemoryStream, file FileStream, or the TCP/IP socket NetWorkStream.

Operations supported by the stream:
 

Read, data is transmitted from Stream to data structure (string or character segment array.

Write, data is transmitted from the data source to the Stream.

Search, query, and modify the position of your Stream.
 

 

Encoding> file and input/output> Stream> create a file Stream

Description: Creates a file path, and specifies the file mode, the access permission is FileAccess, and the shared access permission is FileShare.
 

 

Encoding> file and input/output> Stream> get and set file Stream attributes

Description to determine whether the Stream is readable. It can be set to writable.
 

Create a file stream to obtain and set file stream attributes. Using System;
