Beispiele

Im folgenden Beispiel wird gezeigt, wie Sie eine grundlegende Protokollierung schreiben, die auf Buildereignisse antwortet.The following example shows how to write a basic logger that responds to build events.

using System;
using System.IO;
using System.Security;
using Microsoft.Build.Framework;
using Microsoft.Build.Utilities;

namespace MyLoggers
{
    // This logger will derive from the Microsoft.Build.Utilities.Logger class,
    // which provides it with getters and setters for Verbosity and Parameters,
    // and a default empty Shutdown() implementation.
    public class BasicFileLogger : Logger
    {
        /// <summary>
        /// Initialize is guaranteed to be called by MSBuild at the start of the build
        /// before any events are raised.
        /// </summary>
        public override void Initialize(IEventSource eventSource)
        {
            // The name of the log file should be passed as the first item in the
            // "parameters" specification in the /logger switch.  It is required
            // to pass a log file to this logger. Other loggers may have zero or more than 
            // one parameters.
            if (null == Parameters)

Hinweise

Bei BuildEventArgs der-Klasse handelt es sich um eine Microsoft.Build.Framework abstrakte Basisklasse für alle Ereignis Argument Klassen.The BuildEventArgs class is an abstract base class for all Microsoft.Build.Framework event argument classes.

Konstruktoren

BuildEventArgs()

Eigenschaften

BuildEventContext

Ruft kontextabhängige Speicherortinformationen ab oder legt diese fest.Gets or sets location contextual information. Dies wird an Protokollierungsereignisse angehängt, um zu definieren, wo sich diese in Bezug auf den ausgeführten Prozess bzw. die Engine, das Projekt, das Ziel oder die Aufgabe befinden.This is attached to logging events to define where they are located in relation to the process, engine, project, target, or task that is executing.

HelpKeyword

Ruft das Hilfeschlüsselwort für das Ereignis ab.Gets the Help keyword for the event.

Message

Ruft die Meldung für das Ereignis ab.Gets the message for the event.

SenderName

Ruft den Namen des Object ab, das das Ereignis auslöst.Gets the name of the Object raising the event.

ThreadId

Ruft einen ganzzahligen Bezeichner für den Thread ab, der das Ereignis ausgelöst hat.Gets an integer identifier for the thread that raised the event.

Timestamp

Ruft den Zeitpunkt, zu dem Ereignis ausgelöst wurde, als DateTime ab.Gets the time the event was raised as a DateTime.

Methoden

Equals(Object)

Ermittelt, ob das angegebene Objekt und das aktuelle Objekt gleich sind.Determines whether the specified object is equal to the current object.

(Geerbt von Object)
GetHashCode()

Dient als die Standard-HashfunktionServes as the default hash function.

(Geerbt von Object)
GetType()

Ruft den Type der aktuellen Instanz ab.Gets the Type of the current instance.

(Geerbt von Object)
MemberwiseClone()

Erstellt eine flache Kopie des aktuellen Object.Creates a shallow copy of the current Object.

(Geerbt von Object)
ToString()

Gibt eine Zeichenfolge zurück, die das aktuelle Objekt darstellt.Returns a string that represents the current object.

(Geerbt von Object)
