TraceSwitch.TraceInfo TraceSwitch.TraceInfo TraceSwitch.TraceInfo TraceSwitch.TraceInfo Property

Definition

Gets a value indicating whether the switch allows informational messages.

public:
 property bool TraceInfo { bool get(); };
public bool TraceInfo { get; }
member this.TraceInfo : bool
Public ReadOnly Property TraceInfo As Boolean

Property Value

true if the Level property is set to Info or Verbose; otherwise, false.

Examples

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.Info or higher. However, MyMethod does not write the second error message if 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 Info or higher.
      if ( mySwitch->TraceInfo )
         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();
   }
//Class-level declaration.
 /* Create a TraceSwitch to use in the entire application.*/
 static TraceSwitch mySwitch = new TraceSwitch("General", "Entire Application");
 
 static public void MyMethod() {
    // Write the message if the TraceSwitch level is set to Info or higher.
    if(mySwitch.TraceInfo)
       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.");
 }
 
 public static void Main(string[] args) {
    // Run the method that prints error messages based on the switch level.
    MyMethod();
 }
 
' Class-level declaration.
' Create a TraceSwitch to use in the entire application. 
Private Shared mySwitch As New TraceSwitch("General", "Entire Application")
   
Public Shared Sub MyMethod()
    ' Write the message if the TraceSwitch level is set to Info or higher.
    If mySwitch.TraceInfo Then
        Console.WriteLine("My error message.")
    End If 
    ' Write the message if the TraceSwitch level is set to Verbose.
    If mySwitch.TraceVerbose Then
        Console.WriteLine("My second error message.")
    End If
End Sub

Public Shared Sub Main()
    ' Run the method that prints error messages based on the switch level.
    MyMethod()
End Sub

Remarks

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, informational messages, warnings, and error-handling messages are emitted.
