StreamWriter.Encoding Property


Gets the Encoding in which the output is written.

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

public override Encoding Encoding { get; }

Property Value

Type: System.Text.Encoding

The Encoding specified in the constructor for the current instance, or UTF8Encoding if an encoding was not specified.

This property is necessary for some XML scenarios where a header must be written containing the encoding used by the StreamWriter. This allows the XML code to consume an arbitrary StreamWriter and generate the correct XML header.

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

The following example retrieves the encoding of the specified StreamWriter instance.

// Write out the current text encoding
sw.WriteLine("Encoding: {0}",
