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:worklog1.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="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 > 3000)
            {
                LOGMESSAGE = LOGMESSAGE.Substring(0, 3000);
            }
            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="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 > 3000)
            {
                LOGMESSAGE = LOGMESSAGE.Substring(0, 3000);
            }
            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：

1             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);
2             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());
