  NameDescription
Public methodSupported by the XNA FrameworkCloseCloses the TextReader and releases any system resources associated with the TextReader.
Public methodCreateObjRefCreates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryDispose()Releases all resources used by the TextReader object.
Protected methodSupported by the XNA FrameworkSupported by Portable Class LibraryDispose(Boolean)Releases the unmanaged resources used by the TextReader and optionally releases the managed resources.
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodSupported by the XNA FrameworkSupported by Portable Class LibraryFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetLifetimeServiceRetrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryGetTypeGets the Type of the current instance. (Inherited from Object.)
Public methodInitializeLifetimeServiceObtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
Protected methodSupported by the XNA FrameworkSupported by Portable Class LibraryMemberwiseClone()Creates a shallow copy of the current Object. (Inherited from Object.)
Protected methodMemberwiseClone(Boolean)Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryPeekReads 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.
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryRead()Reads the next character from the input stream and advances the character position by one character.
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryRead(Char[], Int32, Int32)Reads a maximum of count characters from the current stream and writes the data to buffer, beginning at index.
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryReadBlockReads a maximum of count characters from the current stream, and writes the data to buffer, beginning at index.
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryReadLineReads a line of characters from the current stream and returns the data as a string.
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryReadToEndReads all characters from the current position to the end of the TextReader and returns them as one string.
Public methodStatic memberSupported by the XNA FrameworkSynchronizedCreates a thread-safe wrapper around the specified TextReader.
Public methodSupported by the XNA FrameworkSupported by Portable Class LibraryToStringReturns a string that represents the current object. (Inherited from Object.)

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.
