Logger实例程序
这是我写的第一个关于Logger的实例程序：
Codeusing System;
using System.Collections.Generic;
using System.Text;
using System.Diagnostics;
using Microsoft.Practices.EnterpriseLibrary.Common;
using Microsoft.Practices.EnterpriseLibrary.Logging;
using Microsoft.Practices.EnterpriseLibrary.Logging.Configuration;
using Microsoft.Practices.EnterpriseLibrary.Logging.ExtraInformation;
using Microsoft.Practices.EnterpriseLibrary.Logging.Filters;
namespace LoggerExample
{
class Program
{
static void Main(string[] args)
{
LogEntry logEntry = new LogEntry();
logEntry.EventId = 100;
logEntry.Priority = 2;
logEntry.Message = "Sample message";
// logEntry.Categories.Add("UI Events");
// logEntry.Severity = TraceEventType.Information;
// logEntry.Priority = 5;
Logger.Write(logEntry);
Console.WriteLine("The logger has been recorded.");
Console.ReadLine();
}
}
}

还有TerryLee的文章。
重点不在程序如何去写，关键是配置文件，使用微软自带的工具，可以很方便的编辑配置文件：
