BooleanSwitch Constructor (String^, String^)

 

Initializes a new instance of the BooleanSwitch class with the specified display name and description.

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

public:
BooleanSwitch(
	String^ displayName,
	String^ description
)

Parameters

displayName
Type: System::String^

The name to display on a user interface.

description
Type: System::String^

The description of the switch.

When you create a BooleanSwitch, the displayName parameter is used to find initial switch settings. If the constructor cannot find initial settings, the Enabled property is set to false (disabled).

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>
System_CAPS_noteNote

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.

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" );
}
