(. NET Framework 2.0) 2. Concept of stream: A stream is an object used to transmit data. Data transmission has two directions: If the data is transmitted from the external source to the program, this is the read stream; if the data is transmitted from the program to the external source during the summer vacation, This is the write stream. 3. filestream class: used to read and write binary files. To construct a filestream instance, you need the following four pieces of information: (. NET Framew

You can use these classes to call only one operation of a File or folder. FIleInfo DirectoryInfo is a sealed class and needs to be instantiated. Therefore, if you operate a file multiple times, you can use these classes. 2. FileInfo can execute Open (), OpenRead (), OpenText (), OpenWrite (), C

In wince, relative paths cannot be used. absolute paths must be used to locate files. For example, the abc.txt file under the Program Files \ testprogramvisual directory can only be used Program Files \ testprogram \ abc.txtto locate the location, but cannot use abc.txt to locate the location. For example: Private void button#click (Object sender, eventargs E){ String Path = "Program Files \ testwince \ configpio.txt ";Using (streamreader sr = file.
