Parameters

Examples

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.

public ref class BooleanSwitchTest
{
private:

   /* Create a BooleanSwitch for data.*/
   static BooleanSwitch^ dataSwitch = gcnew BooleanSwitch( "Data","DataAccess module" );

public:
   static void MyMethod( String^ location )
   {
      
      //Insert code here to handle processing.
      if ( dataSwitch->Enabled )
            Console::WriteLine( "Error happened at {0}", location );
   }

};

int main()
{
   
   //Run the method which writes an error message specifying the location of the error.
   BooleanSwitchTest::MyMethod( "in main" );
}

// Class level declaration.
/* Create a BooleanSwitch for data.*/
static BooleanSwitch dataSwitch = new BooleanSwitch("Data", "DataAccess module");

static public void MyMethod(string location)
{
    //Insert code here to handle processing.
    if (dataSwitch.Enabled)
        Console.WriteLine("Error happened at " + location);
}

public static void Main(string[] args)
{
    //Run the method which writes an error message specifying the location of the error.
    MyMethod("in Main");
}

' 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

' 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

Remarks

When you create a BooleanSwitch, the displayName parameter is used to find the initial switch settings for .NET Framework apps in the application configuration file. If the constructor cannot find initial settings, or for .NET Core and .NET 5+ apps, the Enabled property is set to false (disabled).

To set the level of your BooleanSwitch in a .NET Framework app, 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>
