在ASP.Net中写系统日志

在ASP.Net中写系统日志

ASP.Net默认情况下，是没有写系统日志的权限的。要在ASP.Net中写系统日志，首先我们要先有其权限。我们可以通过设置或修改注册表的权限来解决。

方法1：“开始->运行”,输入命令，“regedt32”,找到“System->CurrentControlSet->Services->Eventlog”,选择“安全->权限->添加”，然后找到本机的“AspNet”用户，加进来并且给读取权限就好了，加进来后目录中会多一个“aspnet_wp account”

方法2：在注册表：HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Service\EventLog增加User的完全操纵权限

using System;

using System.Diagnostics;

using System.Text;

namespace CorePlus.Framework.Utility

{

 /// <summary>

 /// 写日志的CLASS

 /// </summary>

 public class LogUtility

 {
  public enum EVENT

  {

   /// <summary>重大错误</summary>

   EVENT_ERROR,

   /// <summary>操作失败</summary>

   EVENT_FAILUREAUDIT,

   /// <summary>一般信息</summary>

   EVENT_INFORMATION,

   /// <summary>有效的,成功的操作</summary>

   EVENT_SUCCESSAUDIT,

   /// <summary>警告</summary>

   EVENT_WARNING,

  }

  private static TextWriterTraceListener listner = null;

  /// <summary>

  /// 构造函数

  /// </summary>

  public LogUtility () {}

  /// <param name="loginID">登录ID</param>

  /// <param name="screenID">画面ID</param>

  /// <param name="level">警告级别</param>

  /// <param name="message">日志信息</param>

  public static void Logging (

   string loginID,

   string screenID,

   EVENT level,

   string message )

  {

   // 变量定义

   StringBuilder  outputMessage = null; // 输出的信息

   string    targetLevelString = null;

   EventLogEntryType Eventtype = new EventLogEntryType();

   switch (level)

   {

    case EVENT.EVENT_ERROR:

     Eventtype = EventLogEntryType.Error;

     break;

    case EVENT.EVENT_FAILUREAUDIT:

     Eventtype = EventLogEntryType.FailureAudit;

     break;

    case EVENT.EVENT_INFORMATION:

     Eventtype = EventLogEntryType.Information;

     break;

    case EVENT.EVENT_SUCCESSAUDIT:

     Eventtype = EventLogEntryType.SuccessAudit;

     break;

    case EVENT.EVENT_WARNING:

     Eventtype = EventLogEntryType.Warning;

     break;

   }

   // 日志信息的拼合

   outputMessage = MakeMessage( loginID, screenID, targetLevelString, message );

   // 写日志

   Logging( Eventtype, outputMessage.ToString() );

  }

  /// <summary>

  /// 向日志管理器写日志

  /// </summary>

  /// <param name="level">错误级别</param>

  /// <param name="message">输出的信息</param>

  private static void Logging ( EventLogEntryType level, string message )

  {

   // 变量定义

   string  logName  = null; // 日志名

   string  machineName = null; // 机器名

   string  sourceName = null; // SourceName

   EventLog eventLog = null; // EventLog

   logName  = "Eventlog2";  // 日志名

   machineName = "."; // 机器名

   sourceName = "Eventlog2"; // SourceName

   eventLog = new EventLog( logName, machineName, sourceName );

   eventLog.WriteEntry( message,level );

   eventLog = null;

  }

  /// <summary>

  /// 日志最终拼合

  /// </summary>

  /// <param name="loginID">登录ID</param>

  /// <param name="screenID">画面ID</param>

  /// <param name="levelString">错误级别</param>

  /// <param name="message">日志信息</param>

  /// <returns>输出的日志信息</returns>

  private static StringBuilder MakeMessage (

   string loginID,

   string screenID,

   string levelString,

   string message )

  {

   // 变量定义

   StringBuilder retMessage = new StringBuilder();

   retMessage.Append( "【登录ID】" );

   retMessage.Append( loginID );

   retMessage.Append( "\n【画面ID】" );

   retMessage.Append( screenID );

   retMessage.Append( "\n【错误级别】" );

   retMessage.Append( levelString );

   retMessage.Append( "\n【错误信息】\n" );

   retMessage.Append( message );

   return retMessage;

    }

  }
}

// 在FORM中输出日志

  private void button1_Click(object sender, System.EventArgs e)

  {

   LogUtility.Logging( "bbbbbb","22222222",LogUtility.EVENT.EVENT_ERROR,"3333333" );

  }

运行完程序后打开日志管理器看看~~~~~~~~~怎么样?不错吧,呵呵.

另一个方法

using System;

using System.Collections.Generic;

using System.Text;

using System.Diagnostics;

namespace Log

{

    class LogWirter

    {

        /// <summary>

        /// 事件源名称

        /// </summary>

        private string eventSourceName;

        EventLogEntryType eventLogType;

        public LogWirter()

        {

            eventSourceName = "test";

            eventLogType = EventLogEntryType.Error;

        }

        /// <summary>

        /// 消息事件源名称

        /// </summary>

        public string EventSourceName

        {

            set { eventSourceName = value; }

        }

        /// <summary>

        /// 消息事件类型

        /// </summary>

        public EventLogEntryType EventLogType

        {

            set { eventLogType = value; }

        }

        /// <summary>

        /// 写入系统日志

        /// </summary>

        /// <param name="message">事件内容</param>

        public void LogEvent(string message)

        {

            if (!EventLog.SourceExists(eventSourceName))

            {

                EventLog.CreateEventSource(eventSourceName, "Application");

            }

            EventLog.WriteEntry(eventSourceName, message, EventLogEntryType.Error);

        }

    }
}
