c# - NLog 控制台应用程序

Question

我有一个控制台应用程序，为了记录它的事件，我复制了我在 Web 应用程序中拥有的相同 Nlog.config 文件。我还导入了 Nlog.Extended 和 Nlog.Web。我还检查了 Nlog.config 属性(Build Action = Content，复制到输出目录 = copy Always)并设置了 internalLogFile 和 internalLogLevel。

什么时候

private static Logger logger = LogManager.GetCurrentClassLogger();

被称为 'System.TypeInitializationException' 被抛出，毕竟

Scanning XXXXLayoutRenderer (all parameter in my config)

这是比较我的内部日志文件

Info Found 105 configuration items

没有别的了

这是我的NLog.config文件

这是输出内部日志文件

问题出在哪里？

Answer 1

已找到解决方案!!!我不得不改变这个

<parameter name="@application" layout="${appsetting:key=AppName:default=Unknown}" />

有了这个

<parameter name="@application" layout="${appsetting:name=AppName:default=Unknown}" />

key 词必须替换为 name 词。

已解决。
