Explanation

The TextReader class is used to provide a reader that can read a sequential chain of characters. It is the abstract base class of the StreamReader and StringReader classes. These derived classes can be used to open a text file for reading a specified range of characters, or to create a reader based on an existing stream. A derived class must at least implement the Peek and Read methods to make a functional instance of the TextReader class. Answer: D and C are incorrect. There is no such class as SequentialReader or ChainReader in the System.IO namespace. Answer: A is incorrect. The StringReader class is used to implement a TextReader that reads from a string. It constructs and initializes a new instance of the StringReader class that reads from the specified string. It consists of the following methods: Read(char[], int, int)
