Debug.AutoFlush Property

Definition

Gets or sets a value indicating whether Flush() should be called on the Listeners after every write.

C#
public static bool AutoFlush { get; set; }

Property Value

true if Flush() is called on the Listeners after every write; otherwise, false.

Remarks

The default is false.

Flushing the stream will not flush its underlying encoder unless you explicitly call Flush or Close. Setting AutoFlush to true means that data will be flushed from the buffer to the stream, but the encoder state will not be flushed. This allows the encoder to keep its state (partial characters) so that it can encode the next block of characters correctly. This scenario affects UTF8 and UTF7 where certain characters can only be encoded after the encoder receives the adjacent character or characters.

For .NET Framework apps, you can also set the AutoFlush and IndentSize properties for Debug by editing the configuration file corresponding to the name of your application. The configuration file should be formatted as shown in the following example.

XML
<configuration>
  <system.diagnostics>
    <trace autoflush="true" indentsize="7" />
  </system.diagnostics>
</configuration>
