有没有办法在NLOG中仅设置一次可变值

我试图以ASP.NET核心项目的方式设置NLOG，以使其读取日期，然后根据该日期创建文件目标。这就是我所拥有的：

<variable name ="CurrentDate" value="${longdate}"/>

<targets>
    <target name="MyApp" xsi:type="File"
        fileName="${specialfolder:folder=ApplicationData}/MyApp/${CurrentDate}_MyApp.log"
        layout="${longdate}|${level:uppercase=true}|${message}"
        deleteOldFileOnStartup="false"/>
</targets>

但是我观察到的是，每次应用程序日志发生时，NLOG都会根据发生的时间日志创建一个新文件，该文件在目标目录中产生了巨大的混乱。

我希望在应用程序启动时仅读取一次我只能读取一次的“ CurrentDate”变量，以便每次应用程序启动时都会有一个单独的日志。

有什么想法如何完成？

I am trying to set NLog in ASP.NET Core project in a way that it would read the date ONCE and then create a file target based on that date. This is what I have:

<variable name ="CurrentDate" value="${longdate}"/>

<targets>
    <target name="MyApp" xsi:type="File"
        fileName="${specialfolder:folder=ApplicationData}/MyApp/${CurrentDate}_MyApp.log"
        layout="${longdate}|${level:uppercase=true}|${message}"
        deleteOldFileOnStartup="false"/>
</targets>

However what I've observed is that every time application log occurs, NLog will create a new file based on the time log happened which creates a massive clutter in the target directory.

I would like this "CurrentDate" variable that I am using to be read only once when application starts so that I would have a separate log for each time the application starts.

Any ideas how this could be done?
