Overloads

Write(String, String) Write(String, String) Write(String, String) Write(String, String)

Writes a category name and message to the trace listeners in the Listeners collection.

Write(Object, String) Write(Object, String) Write(Object, String) Write(Object, String)

Writes a category name and the value of the object's ToString() method to the trace listeners in the Listeners collection.

Write(Object) Write(Object) Write(Object) Write(Object)

Writes the value of the object's ToString() method to the trace listeners in the Listeners collection.

Write(String) Write(String) Write(String) Write(String)

Writes a message to the trace listeners in the Listeners collection.

Write(String, String) Write(String, String) Write(String, String) Write(String, String)

Writes a category name and message to the trace listeners in the Listeners collection.

public:
 static void Write(System::String ^ message, System::String ^ category);
[System.Diagnostics.Conditional("DEBUG")]
public static void Write (string message, string category);
static member Write : string * string -> unit
Public Shared Sub Write (message As String, category As String)

Parameters

message
String String String String

A message to write.

category
String String String String

A category name used to organize the output.

Examples

The following example creates a TraceSwitch named generalSwitch. This switch is set outside of the code sample.

If the switch is set to the TraceLevelError or higher, the example outputs the first error message to the Listeners. For information on adding a listener to the Listeners collection, see the TraceListenerCollection class.

Then, if the TraceLevel is set to Verbose, the example outputs the second error message on the same line as the first message. A line terminator follows the second message.

   // Class-level declaration.
   // Create a TraceSwitch.
   static TraceSwitch^ generalSwitch = 
      gcnew TraceSwitch( "General","Entire Application" );

public:
   static void MyErrorMethod( Object^ myObject, String^ category )
   {
      // Write the message if the TraceSwitch level is set to Error or higher.
      if ( generalSwitch->TraceError )
      {
         #if defined(DEBUG)
         Debug::Write( myObject, category );
         #endif
      }
      // Write a second message if the TraceSwitch level is set to Verbose.
      if ( generalSwitch->TraceVerbose )
      {
         #if defined(DEBUG)
         Debug::Write( " Object is not valid for this category." );
         #endif
      }
   }
// Class-level declaration.
 // Create a TraceSwitch.
 static TraceSwitch generalSwitch = new TraceSwitch("General", "Entire Application");
 
 static public void MyErrorMethod(Object myObject, String category) {
    // Write the message if the TraceSwitch level is set to Error or higher.
    if(generalSwitch.TraceError)
       Debug.Write(myObject, category);
 
    // Write a second message if the TraceSwitch level is set to Verbose.
    if(generalSwitch.TraceVerbose)
       Debug.WriteLine(" Object is not valid for this category.");
 }

' Class-level declaration.
' Create a TraceSwitch.
Private Shared generalSwitch As New TraceSwitch("General", "Entire Application")


Public Shared Sub MyErrorMethod(myObject As Object, category As String)
    ' Write the message if the TraceSwitch level is set to Error or higher.
    If generalSwitch.TraceError Then
        Debug.Write(myObject, category)
    End If 
    ' Write a second message if the TraceSwitch level is set to Verbose.
    If generalSwitch.TraceVerbose Then
        Debug.WriteLine(" Object is not valid for this category.")
    End If
End Sub 'MyErrorMethod 

Remarks

By default, the output is written to an instance of DefaultTraceListener.

Use the category parameter to group output messages.

This method calls the Write method of the trace listener.
