NLog 自定义字段 写入 oracle

1、通过Nuget安装NLog 下载，简单入门 请参照 我刚才转的几篇文章，下面我直接贴代码

2、建表语句

 create table TBL_LOG
 (
   id            VARCHAR2(60)  not null,
   appname       VARCHAR2(20),
   modulename    VARCHAR2(30),
   procname      VARCHAR2(30),
   operationtype VARCHAR2(20),
   logger        VARCHAR2(500),
   logmessage    VARCHAR2(3000) not null,
   ip            VARCHAR2(32),
   longdate      VARCHAR2(36),
   username      VARCHAR2(36),
   createdate    DATE default sysdate,
   loglevel      VARCHAR2(12)
 )

3、NLog.config，正式运行 throwExceptions="false"

 <?xml version="1.0" encoding="utf-8" ?>
 <nlog xmlns="http://www.nlog-project.org/schemas/NLog.xsd"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.nlog-project.org/schemas/NLog.xsd NLog.xsd"
       autoReload="true"
       throwExceptions="true"
       internalLogLevel="Info" internalLogFile="d:\work\log1.txt">
   <targets async="true">
     <target name="database" xsi:type="Database" keepConnection="false" useTransactions="true"
                 dbProvider="System.Data.OracleClient.OracleConnection,System.Data.OracleClient, Version=1.0.5000.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
                 connectionString="Data Source=ORCL;User Id=oracle;Password=oracle;Integrated Security=no;"
                 commandText="insert into TBL_LOG(APPNAME,MODULENAME,PROCNAME,OPERATIONTYPE,LOGGER,LOGMESSAGE,IP,LONGDATE,USERNAME,LOGLEVEL) values(:APPNAME,:MODULENAME,:PROCNAME,:OPERATIONTYPE,:LOGGER,:LOGMESSAGE,:IP,:TIME_STAMP,:USERNAME,:LOGLEVEL)">
       <parameter name="APPNAME" layout="${event-context:item=APPNAME}" />
       <parameter name="MODULENAME" layout="${event-context:item=MODULENAME}" />
       <parameter name="PROCNAME" layout="${event-context:item=PROCNAME}" />
       <parameter name="OPERATIONTYPE" layout="${event-context:item=OPERATIONTYPE}" />
       <parameter name="LOGGER" layout="${event-context:item=LOGGER}" />
       <parameter name="LOGMESSAGE" layout="${event-context:item=LOGMESSAGE}" />
       <parameter name="IP" layout="${event-context:item=IP}" />
       <parameter name="TIME_STAMP" layout="${longdate}" />
       <parameter name="USERNAME" layout="${event-context:item=USERNAME}" />
       <parameter name="LOGLEVEL" layout="${level:uppercase=true}" />
     </target>
   </targets>
   <rules>
     <logger name="*" minlevel="Trace"  writeTo="database" />
   </rules>
 </nlog>

4、简单封装

     public class Logger
     {
         #region 初始化
         /// <summary>
         /// 数据错误无法获取用户时使用
         /// </summary>
         public static string DefaultUser = "system";
         /// <summary>
         /// 默认地址
         /// </summary>
         public static string DefaultIP = "127.0.0.1";
         NLog.Logger _logger;
         private Logger(NLog.Logger logger)
         {
             _logger = logger;
         }
         public Logger(string name) : this(LogManager.GetLogger(name))
         { }
         public static Logger Default { get; private set; }
         static Logger()
         {
             Default = new Logger(LogManager.GetCurrentClassLogger());
         }
         #endregion
         #region Process日志写入
         /// <summary>
         /// 日志写入
         /// </summary>
         /// <param name="APPNAME">菜单大类</param>

         /// <param name="IP">ip地址</param>
         /// <param name="USERNAME">用户名</param>
         /// <param name="LOGGER">LOGGER</param>
         public void Process(string APPNAME, string MODULENAME, string PROCNAME, OperationType OPERATIONTYPE, string LOGMESSAGE, string IP, string USERNAME, string LOGGER)
         {
             if (LOGMESSAGE.Length > )
             {
                 LOGMESSAGE = LOGMESSAGE.Substring(, );
             }
             LogEventInfo lei = new LogEventInfo();
             lei.Properties["ID"] = Guid.NewGuid().ToString("D");
             lei.Properties["APPNAME"] = APPNAME;
             lei.Properties["MODULENAME"] = MODULENAME;
             lei.Properties["PROCNAME"] = PROCNAME;
             lei.Properties["OPERATIONTYPE"] = OPERATIONTYPE;
             lei.Properties["LOGMESSAGE"] = LOGMESSAGE;
             lei.Properties["IP"] = IP;
             lei.Properties["USERNAME"] = USERNAME;
             lei.Properties["LOGGER"] = LOGGER;
             lei.Level = LogLevel.Info;
             _logger.Log(lei);
         }
         /// <summary>
         /// 日志写入，自己传日志类别
         /// </summary>
         /// <param name="APPNAME">菜单大类</param>

         /// <param name="LOGGER">LOGGER</param>
         /// <param name="Level">日志级别</param>
         public void Process(string APPNAME, string MODULENAME, string PROCNAME, OperationType OPERATIONTYPE, string LOGMESSAGE, string IP, string USERNAME, string LOGGER, LogLevel Level)
         {
             if (LOGMESSAGE.Length > )
             {
                 LOGMESSAGE = LOGMESSAGE.Substring(, );
             }
             LogEventInfo lei = new LogEventInfo();
             lei.Properties["ID"] = Guid.NewGuid().ToString("D");
             lei.Properties["APPNAME"] = APPNAME;
             lei.Properties["MODULENAME"] = MODULENAME;
             lei.Properties["PROCNAME"] = PROCNAME;
             lei.Properties["OPERATIONTYPE"] = OPERATIONTYPE;
             lei.Properties["LOGMESSAGE"] = LOGMESSAGE;
             lei.Properties["IP"] = IP;
             lei.Properties["USERNAME"] = USERNAME;
             lei.Properties["LOGGER"] = LOGGER;
             lei.Level = Level;
             _logger.Log(lei);
         }
         #endregion
     }
     /// <summary>
     /// 操作类型枚举
     /// </summary>
     public enum OperationType
     {
         /// <summary>
         /// 保存或添加
         /// </summary>
         [System.ComponentModel.Description("保存或添加")]
         ADD,
         /// <summary>
         /// 更新
         /// </summary>
         [System.ComponentModel.Description("更新")]
         UPDATE,
         /// <summary>
         /// 审核
         /// </summary>
         [System.ComponentModel.Description("审核")]
         AUDIT,
         /// <summary>
         /// 删除
         /// </summary>
         [System.ComponentModel.Description("删除")]
         DELETE,
         /// <summary>
         /// 读取/查询
         /// </summary>
         [System.ComponentModel.Description("读取/查询")]
         RETRIEVE,
         /// <summary>
         /// 登录
         /// </summary>
         [System.ComponentModel.Description("登录")]
         LOGIN,
         /// <summary>
         /// 查看
         /// </summary>
         [System.ComponentModel.Description("查看")]
         LOOK
     }

5、asp.net中的调用列子：

             Logger.Default.Process("系统管理", "权限管理", "用户管理", OperationType.RETRIEVE, "测试写入", Logger.DefaultIP, Logger.DefaultUser, this.GetType().ToString(), NLog.LogLevel.Error);
             Logger.Default.Process("系统管理", "权限管理", "用户管理", OperationType.RETRIEVE, "测试写入", Logger.DefaultIP, Logger.DefaultUser, this.GetType().ToString());
