TraceSwitch::TraceWarning Property
Gets a value indicating whether the switch allows warning messages.
Assembly: System (in System.dll)
Property Value
Type: System::Booleantrue if the Level property is set to TraceLevel::Warning, TraceLevel::Info, or TraceLevel::Verbose; otherwise, false.
You can use the TraceError, TraceWarning, TraceInfo, and TraceVerbose properties in conjunction with the Debug and Trace classes to emit all messages with a specified importance or greater. When the Level property is set to TraceLevel::Warning, warnings and error-handling messages are emitted.
The following code example creates a new TraceSwitch and uses the switch to determine whether to emit error messages. The switch is created at the class level. MyMethod writes the first error message if the Level property is set to TraceLevel::Warning or higher. However, MyMethod does not write the second error message when the Level is less than TraceLevel::Verbose.
// Class-level declaration. /* Create a TraceSwitch to use in the entire application.*/ private: static TraceSwitch^ mySwitch = gcnew TraceSwitch( "General", "Entire Application" ); public: static void MyMethod() { // Write the message if the TraceSwitch level is set to Warning or higher. if ( mySwitch->TraceWarning ) Console::WriteLine( "My error message." ); // Write the message if the TraceSwitch level is set to Verbose. if ( mySwitch->TraceVerbose ) Console::WriteLine( "My second error message." ); } static void main() { // Run the method that prints error messages based on the switch level. MyMethod(); }
