Logging.dll, Microsoft.Practices.EnterpriseLibrary. Logging.Database.dll并添加需要的引用: 添加引用: using Microsoft.Practices.EnterpriseLibrary. Logging; 5. 测试: using System;using System.Collections.Generic;using System.Linq;using System.Text;using Microsoft.Practices.EnterpriseLibrary.Logging;namespace ConsoleApplication1{class Program {staticvoid Main(string[] args) { LogEntry logEntry new LogEntry(); logEntry.EventId 1; logEntry.Priority 1; logEntry.Title 标题党; logEntry.Message http://www.cnblogs.com/huangcong/; logEntry.Categories.Add(C#学习); logEntry.Categories.Add(Microsoft Enterprise Library学习); Logger.Writer.Write(logEntry, General); Console.WriteLine(日志写入完成!); } }} 运行结果: 6. 开始—控制面板—系统和安全—查看事件日志—Windows日志—应用程序: 7. 第一个日志就是我们刚刚写入的日志啦,双击可以查看内容: 二. 向数据库写入日记 1. 要将日志写入数据库,就得先新建一个日志数据库,我们可以在EntLib50Src文件夹下的Source\Blocks\Logging\Src\DatabaseTraceListener\Scripts目录中找到LoggingDatabase.sql文件,只要在数据库中运行即可自动生成一个日志数据库: 为了方便大家,我直接将该文件发布在下面,大家直接复制到SQL中运行也可以: Logging数据库创建SQL /****** Object: Database Logging Script Date: 8/22/2005 ******/USE[master]GOIFEXISTS (SELECT name FROM master.dbo.sysdatabases WHERE name NLogging)DROPDATABASE[Logging]GOCREATEDATABASE[Logging] COLLATE SQL_Latin1_General_CP1_CI_ASGOexec sp_dboption NLogging, Nautoclose, NfalseGOexec sp_dboption NLogging, Nbulkcopy, NfalseGOexec sp_dboption NLogging, Ntrunc. log, NfalseGOexec sp_dboption NLogging, Ntorn page detection, NtrueGOexec sp_dboption NLogging, Nread only, NfalseGOexec sp_dboption NLogging, Ndbo use, NfalseGOexec sp_dboption NLogging, Nsingle, NfalseGOexec sp_dboption NLogging, Nautoshrink, NfalseGOexec sp_dboption NLogging, NANSI null default, NfalseGOexec sp_dboption NLogging, Nrecursive triggers, NfalseGOexec sp_dboption NLogging, NANSI nulls, NfalseGOexec sp_dboption NLogging, Nconcat null yields null, NfalseGOexec sp_dboption NLogging, Ncursor close on commit, NfalseGOexec sp_dboption NLogging, Ndefault to local cursor, NfalseGOexec sp_dboption NLogging, Nquoted identifier, NfalseGOexec sp_dboption NLogging, NANSI warnings, NfalseGOexec sp_dboption NLogging, Nauto create statistics, NtrueGOexec sp_dboption NLogging, Nauto update statistics, NtrueGOuse[Logging]GOSET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOIFNOTEXISTS (SELECT*FROM dbo.sysobjects WHERE id OBJECT_ID(N[dbo].[Category]) ANDOBJECTPROPERTY(id, NIsUserTable) 1)BEGINCREATETABLE[dbo].[Category]([CategoryID][int]IDENTITY(1,1) NOTNULL,[CategoryName][nvarchar](64) NOTNULL,CONSTRAINT[PK_Categories]PRIMARYKEYCLUSTERED([CategoryID]ASC) ON[PRIMARY]) ON[PRIMARY]ENDGOSET ANSI_NULLS OFFGOSET QUOTED_IDENTIFIER OFFGOSET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOIFNOTEXISTS (SELECT*FROM dbo.sysobjects WHERE id OBJECT_ID(N[dbo].[CategoryLog]) ANDOBJECTPROPERTY(id, NIsUserTable) 1)BEGINCREATETABLE[dbo].[CategoryLog]([CategoryLogID][int]IDENTITY(1,1) NOTNULL,[CategoryID][int]NOTNULL,[LogID][int]NOTNULL,CONSTRAINT[PK_CategoryLog]PRIMARYKEYCLUSTERED([CategoryLogID]ASC) ON[PRIMARY]) ON[PRIMARY]ENDGOSET ANSI_NULLS OFFGOSET QUOTED_IDENTIFIER OFFGOSET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOIFNOTEXISTS (SELECT*FROM dbo.sysobjects WHERE id OBJECT_ID(N[dbo].[Log]) ANDOBJECTPROPERTY(id, NIsUserTable) 1)BEGINCREATETABLE[dbo].[Log]([LogID][int]IDENTITY(1,1) NOTNULL,[EventID][int]NULL,[Priority][int]NOTNULL,[Severity][nvarchar](32) NOTNULL,[Title][nvarchar](256) NOTNULL,[Timestamp][datetime]NOTNULL,[MachineName][nvarchar](32) NOTNULL,[AppDomainName][nvarchar](512) NOTNULL,[ProcessID][nvarchar](256) NOTNULL,[ProcessName][nvarchar](512) NOTNULL,[ThreadName][nvarchar](512) NULL,[Win32ThreadId][nvarchar](128) NULL,[Message][nvarchar](1500) NULL,[FormattedMessage][ntext]NULL,CONSTRAINT[PK_Log]PRIMARYKEYCLUSTERED([LogID]ASC) ON[PRIMARY]) ON[PRIMARY] TEXTIMAGE_ON [PRIMARY]ENDGOSET ANSI_NULLS OFFGOSET QUOTED_IDENTIFIER OFFGOSET ANSI_NULLS ONGOSET QUOTED_IDENTIFIER ONGOIFNOTEXISTS (SELECT*FROM sysobjects WHERE id OBJECT_ID(N[dbo].[InsertCategoryLog]) AND type in (NP, NPC))BEGINEXEC dbo.sp_executesql statement NCREATE PROCEDURE InsertCategoryLog CategoryID INT, LogID INTASBEGIN SET NOCOUNT ON;
