BooleanSwitch Constructor (String, String)
Initializes a new instance of the BooleanSwitch class with the specified display name and description.
Assembly: System (in System.dll)
To set the level of your BooleanSwitch, edit the configuration file corresponding to the name of your application. Within this file, you can add a switch and set its value, remove a switch, or clear all switches previously set by the application. 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>
The switches you created should be static.
The following example creates a BooleanSwitch and uses the switch to determine whether to print an error message. The switch is created at the class level. The Main method passes its location to MyMethod, which prints an error message and where the error occurred.
' Class level declaration. ' Create a BooleanSwitch for data. Private Shared dataSwitch As New BooleanSwitch("Data", "DataAccess module") Public Shared Sub MyMethod(location As String) ' Insert code here to handle processing. If dataSwitch.Enabled Then Console.WriteLine(("Error happened at " + location)) End If End Sub 'MyMethod ' Entry point which delegates to C-style main function. Public Overloads Shared Sub Main() Main(System.Environment.GetCommandLineArgs()) End Sub Overloads Public Shared Sub Main(args() As String) ' Run the method which writes an error message specifying the location of the error. MyMethod("in Main") End Sub 'Main
