Methods

	Name	Description
	Close	Closes the TextReader and releases any system resources associated with the TextReader.
	Dispose()	Releases all resources used by the TextReader object.
	Dispose(Boolean)	Releases the unmanaged resources used by the TextReader and optionally releases the managed resources.
	Equals(Object)	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	Peek	Reads the next character without changing the state of the reader or the character source. Returns the next available character without actually reading it from the input stream.
	Read()	Reads the next character from the input stream and advances the character position by one character.
	Read(array<Char[], Int32, Int32)	Reads a maximum of count characters from the current stream and writes the data to buffer, beginning at index.
	ReadBlock	Reads a maximum of count characters from the current stream, and writes the data to buffer, beginning at index.
	ReadLine	Reads a line of characters from the current stream and returns the data as a string.
	ReadToEnd	Reads all characters from the current position to the end of the TextReader and returns them as one string.
	ToString	Returns a string that represents the current object. (Inherited from Object.)

Remarks

TextReader is the abstract base class of StreamReader and StringReader, which read characters from streams and strings, respectively. Use these derived classes to open a text file for reading a specified range of characters, or to create a reader based on an existing stream.

Notes to Inheritors

A derived class must minimally implement the Peek and Read methods to make a useful instance of TextReader.
