次の例は、ビルドイベントに応答する基本的なロガーを記述する方法を示しています。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)
			{

				(
					ex is UnauthorizedAccessException

			// register to handle TargetStarted/Finished and other events.

			// Just the regular message string is good enough here, so just display that.

		{

注釈

この例外は、無効なパラメーターを受信したこと、または何らかの理由でログ記録を続行できなくなり、制御された方法で停止することをホストに示すために、logger によって使用されます。This exception can be used by a logger to indicate to a host that it has received invalid parameters, or can no longer continue logging for some reason, and wants to stop in a controlled way.
