 property bool Enabled { bool get(); void set(bool value); };

public bool Enabled { get; set; }

member this.Enabled : bool with get, set

Public Property Enabled As Boolean

Property Value

Boolean

true if the switch is enabled; otherwise, false. The default is false.

Exceptions

SecurityException

The caller does not have the correct permission.

Examples

The following code 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 the location 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 that 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 that 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 Private Function
Public Overloads Shared Sub Main()
    Main(System.Environment.GetCommandLineArgs())
End Sub
 
Overloads Public Shared Sub Main(args() As String)
    'Run the method that writes an error message specifying the location of the error.
    MyMethod("in Main")
End Sub

Remarks

By default, this field is set to false (disabled). To enable the switch, assign this field the value of true. To disable the switch, assign the value to false. The value of this property is determined by the value of the base class property SwitchSetting.
