Methods

  Name Description
Public method Close Closes the current writer and releases any system resources associated with the writer.
Public method Dispose() () () () Releases all resources used by the TextWriter object.
Protected method Dispose(Boolean) Releases the unmanaged resources used by the TextWriter and optionally releases the managed resources.
Public method Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected method Finalize Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public method Flush Clears all buffers for the current writer and causes any buffered data to be written to the underlying device.
Public method GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
Public method GetType Gets the Type of the current instance. (Inherited from Object.)
Protected method MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
Public method ToString Returns a string that represents the current object. (Inherited from Object.)
Public method Write(Boolean) Writes the text representation of a Boolean value to the text string or stream.
Public method Write(Char) Writes a character to the text string or stream.
Public method Write(array<Char> [] () [] []) Writes a character array to the text string or stream.
Public method Write(Double) Writes the text representation of an 8-byte floating-point value to the text string or stream.
Public method Write(Int32) Writes the text representation of a 4-byte signed integer to the text string or stream.
Public method Write(Int64) Writes the text representation of an 8-byte signed integer to the text string or stream.
Public method Write(Object) Writes the text representation of an object to the text string or stream by calling the ToString method on that object.
Public method Write(Single) Writes the text representation of a 4-byte floating-point value to the text string or stream.
Public method Write(String) Writes a string to the text string or stream.
Public method Write(UInt32) Writes the text representation of a 4-byte unsigned integer to the text string or stream.
Public method Write(UInt64) Writes the text representation of an 8-byte unsigned integer to the text string or stream.
Public method Write(array<Char> [] () [] [], Int32, Int32) Writes a subarray of characters to the text string or stream.

Public method WriteLine(Boolean) Writes the text representation of a Boolean value followed by a line terminator to the text string or stream.
Public method WriteLine(Char) Writes a character followed by a line terminator to the text string or stream.
Public method WriteLine(array<Char> [] () [] []) Writes an array of characters followed by a line terminator to the text string or stream.

Public method WriteLine(Int64) Writes the text representation of an 8-byte signed integer followed by a line terminator to the text string or stream.
Public method WriteLine(Object) Writes the text representation of an object by calling the ToString method on that object, followed by a line terminator to the text string or stream.
Public method WriteLine(Single) Writes the text representation of a 4-byte floating-point value followed by a line terminator to the text string or stream.
Public method WriteLine(String) Writes a string followed by a line terminator to the text string or stream.
Public method WriteLine(UInt32) Writes the text representation of a 4-byte unsigned integer followed by a line terminator to the text string or stream.
Public method WriteLine(UInt64) Writes the text representation of an 8-byte unsigned integer followed by a line terminator to the text string or stream.

Fields

Remarks

TextWriter is the abstract base class of StreamWriter and StringWriter, which write characters to streams and strings, respectively. Create an instance of TextWriter to write an object to a string, write strings to a file, or to serialize XML. You can also use an instance of TextWriter to write text to a custom backing store using the same APIs you would use for a string or a stream, or to add support for text formatting.

All the Write methods of TextWriter having primitive data types as parameters write out the values as strings.

Notes to Inheritors

A derived class must minimally implement the TextWriter..::..Write(Char) method to make a useful instance of TextWriter.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
