Switch Constructor (String, String)

Initializes a new instance of the Switch class.

Namespace:  System.Diagnostics
Assembly:  System (in System.dll)

'Declaration
Protected Sub New ( _
	displayName As String, _
	description As String _
)

Parameters

displayName
Type: System.String

The name of the switch.

description
Type: System.String

The description for the switch.

When you create a new Switch object, the value of the displayName parameter is used to find initial switch settings. The default value is an empty string ("").

Within the XML configuration file, you can add a switch and set its value, remove a switch, or clear all the switches previously set by the application. Dynamic changes to the configuration file are not detected while the application is executing. You must stop and restart an application before changes to the configuration file take effect. The configuration file should be formatted like the following example:

<configuration>
  <system.diagnostics>
    <switches>
      <add name="mySwitch" value="10" />
      <add name="myNewSwitch" value="20" />
      <remove name="mySwitch" />
      <clear/>
    </switches>
  </system.diagnostics>
</configuration>

Notes to Inheritors

To set the value of the switch, set the SwitchSetting property in the constructor.
