BinaryWriter.Write Method (String)

Writes a length-prefixed string to this stream in the current encoding of the BinaryWriter, and advances the current position of the stream in accordance with the encoding used and the specific characters being written to the stream.

Namespace:  System.IO
Assembly:  mscorlib (in mscorlib.dll)

abstract Write : 
        value:string -> unit 
override Write : 
        value:string -> unit 

Parameters

value
Type: System.String
The value to write.

ExceptionCondition
IOException

An I/O error occurs.

ArgumentNullException

value is a null reference (Nothing in Visual Basic).

ObjectDisposedException

The stream is closed.

A length-prefixed string represents the string length by prefixing to the string a single byte or word that contains the length of that string. This method first writes the length of the string as a UTF-7 encoded unsigned integer, and then writes that many characters to the stream by using the BinaryWriter instance's current encoding.

For a list of common I/O tasks, see Common I/O Tasks.

This example demonstrates how Write adds the length prefix when it writes a string. The string data is first read as a sequence of raw bytes and its length is calculated. Next, a BinaryReader reads the string directly. The output from both string retrievals is displayed.
