* Short answer 1. 1) The file must be opened. If the file does not yet exist, opening it means creating it. 2) Data is written to the file or read from the file. 3) When the application is finished using the file, the file is closed 2. The close method writes any unsaved information remaining in the file buffer and releases memory allocated by the StreamWriter object. 3. Data is rad in forward-only direction. When the file is opened, its read position, the position of the next item to be read, is set to the first item in the file. As data is read, the read position advances through the file. 4. The WriteLine method writes the data to the file and then writes a newline character immediately after the data. The Write method can be used to write data to a file without terminating the line with a newline character. 5. An exception will occur. 6. If the current read position is at the end of the file, the method returns -1. 7. The ReadLine method returns the data as a string. 8. The Read method returns the integer code for the character. 9. When the Print method is called, it triggers a PrintPage event. PrintPage event handler, you can write code that sends text to the printer using a specified font and color at specified location. 10. If you use the Public access specifier, the structure is accessible to statements outside the class or module. If you use the private access specifier, the structure is accessible only to statements in the same class or module.

* What do you think? 1. This technique improves the system’s performance because writing data to meory is faster then writing it to a disk. 2.
