无法使NLog的数据库目标正常工作。我有2个目标:FILE和DB ..这是我的 NLog.config :
<?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"
autoReload="true"
throwExceptions="false">
<variable name="appName" value="KoreCMS" />
<targets async="true">
<target xsi:type="File"
name="default"
layout="${longdate} - ${level:uppercase=true}: ${message}${onexception:${newline}EXCEPTION\: ${exception:format=ToString}}"
fileName="${basedir}\App_Data\Log\Debug.log"
keepFileOpen="false"
archiveFileName="${basedir}\App_Data\Log\Debug_${shortdate}.{##}.log"
archiveNumbering="Sequence"
archiveEvery="Day"
maxArchiveFiles="30"/>
<target xsi:type="Database"
name="database"
keepConnection="true"
useTransactions="true"
dbProvider="System.Data.SqlClient"
connectionStringName="DefaultConnection"
commandText="INSERT INTO Kore_Log(EventDateTime, EventLevel, UserName, MachineName, EventMessage, ErrorSource, ErrorClass, ErrorMethod, ErrorMessage, InnerErrorMessage) VALUES (@EventDateTime, @EventLevel, @UserName, @MachineName, @EventMessage, @ErrorSource, @ErrorClass, @ErrorMethod, @ErrorMessage, @InnerErrorMessage)">
<parameter name="@EventDateTime" layout="${date:s}" />
<parameter name="@EventLevel" layout="${level}" />
<parameter name="@UserName" layout="${aspnet-user-identity}" />
<parameter name="@MachineName" layout="${machinename}" />
<parameter name="@EventMessage" layout="${message}" />
<parameter name="@ErrorSource" layout="${event-context:item=error-source}" />
<parameter name="@ErrorClass" layout="${event-context:item=error-class}" />
<parameter name="@ErrorMethod" layout="${event-context:item=error-method}" />
<parameter name="@ErrorMessage" layout="${event-context:item=error-message}" />
<parameter name="@InnerErrorMessage" layout="${event-context:item=inner-error-message}" />
</target>
</targets>
<rules>
<logger name="*" writeTo="default" minlevel="Info" />
<logger name="*" writeTo="database" minlevel="Info" />
</rules>
</nlog>
这是数据库设计:
这是连接字符串:
<connectionStrings>
<add name="DefaultConnection" connectionString="Server=.\SQLExpress2012;Initial Catalog=MyDatabaseName;Integrated Security=True;Persist Security Info=True;MultipleActiveResultSets=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
我错过了什么?

好吧,我想通了......当我打开 SQL Profiler 时,我看到确实发送了 INSERT 命令,所以我试图运行同样地命令我自己,发现我是个白痴;基本上,我的 ID 列设置为 uniqueidentifier ,因此当然无法自动递增。解决方案是将 Nlog.config 中的 commandText 更改为以下内容:
commandText="INSERT INTO Kore_Log(Id, EventDateTime, EventLevel, UserName, MachineName, EventMessage, ErrorSource, ErrorClass, ErrorMethod, ErrorMessage, InnerErrorMessage) VALUES (NEWID(), @EventDateTime, @EventLevel, @UserName, @MachineName, @EventMessage, @ErrorSource, @ErrorClass, @ErrorMethod, @ErrorMessage, @InnerErrorMessage)">

我遇到了同样的问题,原因是nlog.config中的 dbProvider 值和 connectionStringName 键。我是从here
获得的 <target name="database" xsi:type="Database" connectionString="${configsetting:name=sqlconnection.connectionString}"
dbProvider="Microsoft.Data.SqlClient.SqlConnection, Microsoft.Data.SqlClient">
