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

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.Level = LogLevel.Info;
_logger.Log(lei);
}

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());
