未创建 NLog 数据库

Question

我是第一次设置 nlog，并且有多个位置可以记录...这是我在 nlog 中的设置，但从未创建表？

<target xsi:type="Database"
       name="DatabaseTarget"
       keepConnection="true"
       commandType="Text"
       dbDatabase="IISLogging"
       dbUserName="user"
       dbPassword="password"
       dbHost="111.111.11.1"
       commandText="INSERT INTO [Log] (Logged,Level,LogMessage,Exception,StackTrace,Path,Json,Ip) 
                    VALUES (@Logged, @Level, @Message, @Exception, @StackTrace,@Path,@Json,@Ip)">

假设nlog.config 正确填写了您的数据库提供者的正确值，您可以使用数据库目标的安装功能。

LogManager.Configuration.Install(new InstallationContext());

安装数据库目标示例

<target xsi:type="Database" name="db"
        connectionStringName="LoggingDatabase">
    <install-command>
        <text>
            <!--
            NOTE: call LogManager.Configuration.Install(new InstallationContext()); 
                  to execute this query.
            -->
            CREATE TABLE ${var:logTableName} (
            Id bigint primary key not null identity(1,1),
            Logged datetime2,
            Level nvarchar(10),
            LogMessage nvarchar(max),
            MessageUid uniqueidentifier,
            MessagePartUid uniqueidentifier,
            MessagePartDataUid uniqueidentifier,
            )
        </text>
        <ignoreFailures>false</ignoreFailures>
    </install-command>

另外，请尝试使用内部记录器进行故障排除

<nlog internalLogLevel="Debug"
      internalLogFile="c:\temp\nlog-internal.txt"
      internalLogToConsole="true"
      throwConfigExceptions="true">
    <targets>
