次の例では、ビルド イベントに応答する基本的なロガーを作成する方法を示します。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)
			{
				throw new LoggerException("Log file was not set.");
			}
			string[] parameters = Parameters.Split(';');
			
			string logFile = parameters[0];
			if (String.IsNullOrEmpty(logFile))
			{
				throw new LoggerException("Log file was not set.");
			}
			
			if (parameters.Length > 1)
			{
				throw new LoggerException("Too many parameters passed.");
			}
			
			try
			{
				// Open the file
				this.streamWriter = new StreamWriter(logFile);
			}
			catch (Exception ex)
			{
				if
				(
					ex is UnauthorizedAccessException
					|| ex is ArgumentNullException
					|| ex is PathTooLongException
					|| ex is DirectoryNotFoundException
					|| ex is NotSupportedException
					|| ex is ArgumentException
					|| ex is SecurityException
					|| ex is IOException
				)
				{
					throw new LoggerException("Failed to create log file: " + ex.Message);
				}
				else
				{
					// Unexpected failure
					throw;
				}
			}

			// For brevity, we'll only register for certain event types. Loggers can also
			// register to handle TargetStarted/Finished and other events.
			eventSource.ProjectStarted += new ProjectStartedEventHandler(eventSource_ProjectStarted);
			eventSource.TaskStarted += new TaskStartedEventHandler(eventSource_TaskStarted);
			eventSource.MessageRaised += new BuildMessageEventHandler(eventSource_MessageRaised);
			eventSource.WarningRaised += new BuildWarningEventHandler(eventSource_WarningRaised);
			eventSource.ErrorRaised += new BuildErrorEventHandler(eventSource_ErrorRaised);
			eventSource.ProjectFinished += new ProjectFinishedEventHandler(eventSource_ProjectFinished);
		}

		void eventSource_ErrorRaised(object sender, BuildErrorEventArgs e)
		{
			// BuildErrorEventArgs adds LineNumber, ColumnNumber, File, amongst other parameters
			string line = String.Format(": ERROR {0}({1},{2}): ", e.File, e.LineNumber, e.ColumnNumber);
			WriteLineWithSenderAndMessage(line, e);
		}
		
		void eventSource_WarningRaised(object sender, BuildWarningEventArgs e)
		{
			// BuildWarningEventArgs adds LineNumber, ColumnNumber, File, amongst other parameters
			string line = String.Format(": Warning {0}({1},{2}): ", e.File, e.LineNumber, e.ColumnNumber);
			WriteLineWithSenderAndMessage(line, e);
		}

		void eventSource_MessageRaised(object sender, BuildMessageEventArgs e)
		{
			// BuildMessageEventArgs adds Importance to BuildEventArgs
			// Let's take account of the verbosity setting we've been passed in deciding whether to log the message
			if ((e.Importance == MessageImportance.High && IsVerbosityAtLeast(LoggerVerbosity.Minimal))
				|| (e.Importance == MessageImportance.Normal && IsVerbosityAtLeast(LoggerVerbosity.Normal))
				|| (e.Importance == MessageImportance.Low && IsVerbosityAtLeast(LoggerVerbosity.Detailed))				
				)
			{
				WriteLineWithSenderAndMessage(String.Empty, e);
			}
		}

		void eventSource_TaskStarted(object sender, TaskStartedEventArgs e)
		{
			// TaskStartedEventArgs adds ProjectFile, TaskFile, TaskName
			// To keep this log clean, this logger will ignore these events.
		}
		
		void eventSource_ProjectStarted(object sender, ProjectStartedEventArgs e)
		{
			// ProjectStartedEventArgs adds ProjectFile, TargetNames
			// Just the regular message string is good enough here, so just display that.
			WriteLine(String.Empty, e);
			indent++;
		}

		void eventSource_ProjectFinished(object sender, ProjectFinishedEventArgs e)
		{
			// The regular message string is good enough here too.
			indent--;
			WriteLine(String.Empty, e);
		}
		
		/// <summary>
		/// Write a line to the log, adding the SenderName and Message
		/// (these parameters are on all MSBuild event argument objects)
		/// </summary>
		private void WriteLineWithSenderAndMessage(string line, BuildEventArgs e)
		{
			if (0 == String.Compare(e.SenderName, "MSBuild", true /*ignore case*/))
			{
				// Well, if the sender name is MSBuild, let's leave it out for prettiness
				WriteLine(line, e);
			}
			else
			{
				WriteLine(e.SenderName + ": " + line, e);
			}
		}
		
		/// <summary>
		/// Just write a line to the log
		/// </summary>
		private void WriteLine(string line, BuildEventArgs e)
		{
			for (int i = indent; i > 0; i--)
			{
				streamWriter.Write("\t");
			}
			streamWriter.WriteLine(line + e.Message);
		}
		
		/// <summary>
		/// Shutdown() is guaranteed to be called by MSBuild at the end of the build, after all 
		/// events have been raised.
		/// </summary>
		public override void Shutdown()
		{
			// Done logging, let go of the file
			streamWriter.Close();
