SourceSwitch Constructor (String, String)

Initializes a new instance of the SourceSwitch class, specifying the display name and the default value for the source switch.

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

public SourceSwitch(
	string displayName,
	string defaultSwitchValue
)

Parameters

displayName
Type: System.String

The name of the source switch.

defaultSwitchValue
Type: System.String

The default value for the switch.

The displayName parameter is used to set the value of the DisplayName property; the defaultSwitchValue parameter is saved as a field and used to initialize the Value property on first reference.

NoteNote

If the switch is defined in a configuration file and the value attribute is specified, the configuration file value takes precedence and the defaultSwitchValue is ignored.

To set the level of your SourceSwitch, edit the configuration file that corresponds to the name of your application. Within this file, you can add a switch and set its value, remove a switch, or clear all the switches previously set by the application. To add a source switch, the configuration file should be formatted as shown in the following example.

<configuration>
  <system.diagnostics>
    <switches>
      <add name="SourceSwitch" value="Verbose" ></add>
    </switches>
  </system.diagnostics>
</configuration>

The following code example creates a SourceSwitch with the name "SourceSwitch" and a default value of Verbose. This code example is part of a larger example provided for the TraceSource class.

#if(!ConfigFile)
                SourceSwitch sourceSwitch = new SourceSwitch("SourceSwitch", "Verbose");
#endif
