EnterpriseLibrary6.0 log2database

一、引用EnterpriseLibrary6.0相關dll

二、安裝Microsoft.Practices.EnterpriseLibrary.ConfigConsoleV6.vsix

　　主要爲了方便編輯config文件，不是必須安裝，安裝後須要更改解決方案屬性，將Enterprise Library v6 binaries path 指向企業庫6.0的bin目錄

三、執行sql腳本建立記錄日誌的數據庫、存儲過程、表

　　下載的包中提供了腳本，目錄：Enterprise Library 6\devguidesamples\Logging\Scripts\LoggingDatabase.sql

四、配置config文件

五、實例代碼

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 using Microsoft.Practices.EnterpriseLibrary.Data;
 7 using Microsoft.Practices.EnterpriseLibrary.Common.Configuration;
 8 using System.Data.Common;
 9 using System.Data;
10 using Microsoft.Practices.EnterpriseLibrary.Logging;

12 namespace EntLib6Test
13 {
14     class Program
15     {
16 
17         static void Main(string[] args)
18         {
19 
20             IConfigurationSource configurationSource = ConfigurationSourceFactory.Create();
21             DatabaseFactory.SetDatabaseProviderFactory(new DatabaseProviderFactory(configurationSource), false);

23             Logger.SetLogWriter(logWriterFactory.Create(), false);
24 
25 
26             string sql = @"SELECT Name from T_UserBase";
27 
28             DatabaseProviderFactory factory = new DatabaseProviderFactory();
29             Database db = factory.CreateDefault();
30 
31             using (DbCommand sqlCmd = db.GetSqlStringCommand(sql))
32             {
33                 DataSet userList = db.ExecuteDataSet(sqlCmd);

38                     {
39                         Console.WriteLine(userList.Tables[0].Rows[i]["Name"].ToString());
40                     }

六、注意事項

　　記錄日誌到數據庫代碼中須要加入如下代碼，不然會報錯

1             IConfigurationSource configurationSource = ConfigurationSourceFactory.Create();
2             DatabaseFactory.SetDatabaseProviderFactory(new DatabaseProviderFactory(configurationSource), false);
3             LogWriterFactory logWriterFactory = new LogWriterFactory(configurationSource);
4             Logger.SetLogWriter(logWriterFactory.Create(), false);

View Code

　　調試中異常信息並不能寫入數據庫，編譯後以管理員身份運行會才能寫入數據庫，解決方法待確認

 

　　事件查看器發佈後能夠寫入日誌須要對Event Log Listener中的source作如下操做

　　<!-- source 值爲 Enterprise Library Logging 　　就須要在註冊表 　　HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application 　　上右鍵加一個項名稱也叫 Enterprise Library Logging 不然發佈後日志不會成功記錄 　　-->
