TextWriterTraceListener.Close Método

Definición

Cierra Writer para que ya no se reciba ningún resultado de la traza o la depuración.Closes the Writer so that it no longer receives tracing or debugging output.

public:
 override void Close();
public override void Close ();
override this.Close : unit -> unit
Public Overrides Sub Close ()

Ejemplos

En el ejemplo siguiente se implementa una TextWriterTraceListener denominada myTextListener, que utiliza una StreamWriter denominada myOutputWriter para escribir en un archivo denominado TestFile.txt.The following example implements a TextWriterTraceListener named myTextListener, which uses a StreamWriter called myOutputWriter to write to a file named TestFile.txt. En el ejemplo se crea el archivo, el flujo y el escritor de texto, se escribe una línea de texto en el archivo y, a continuación, se vacía y se cierra la secuencia.The example creates the file, stream, and text writer, writes one line of text to the file, and then flushes and closes the stream.

Comentarios

Llamar a un método Write o WriteLine después de llamar a Close vuelve a abrir automáticamente la secuencia.Calling a Write or WriteLine method after calling Close automatically reopens the stream.
