Chapter 10 – Working with Files, Streams, and Serialization

1. What is the difference between using the File class and the FileInfo class?

   The File class has static methods so it cannot be instantiated. It is best used for one-off tasks such as copying a file. The FileInfo class requires the instantiation of an object that represents a file. It is best used when you need to perform multiple operations on the same file.

2. What is the difference between the ReadByte method and the Read method of a stream?

   The ReadByte method returns a single byte each time it is called and the Read method fills a temporary array with bytes up to a specified length. It is generally best to use Read to process blocks of bytes at once.

3. When would you use the StringReader, the TextReader, and the StreamReader classes?
   • StringReader is used for efficiently reading from a string stored in memory
   • TextReader is an abstract class that StringReader and StreamReader both inherit from for their shared functionality
   • StreamReader...
