NLog 4.1.2 在构造函数中崩溃

Question

我有一个程序在这个星期一 (2018-10-01) 工作，但在星期三开始崩溃（它在星期二没有使用）。

程序在客户处，处于发布状态，无法调试！客户说"Nothing has changed"，我程序里的所有文件都和以前一样

这是一个 C# Winforms 程序，我通过事件查看器发现崩溃发生在 NLog 启动时（在 ctor 中）。

我尝试使用内部日志记录，但没有创建日志文件。

关于问题是什么的任何想法and/or我应该如何解决它？

事件查看器应用程序中的消息：

NLog.config 文件

<?xml version="1.0" encoding="utf-8" ?>
<nlog throwExceptions="true"
internalLogFile="C:/Temp/log.txt" internalLogLevel="Trace">
  <targets>
    <target xsi:type="File" name="f" fileName="${specialfolder:folder=CommonApplicationData}/Foo/Bar/Logs/Bar_${shortdate}.log"
            layout="${longdate} | ${uppercase:${level}} | ${callsite} | ${message} | ${exception:format=ToString}" />
  </targets>

  <rules>
    <logger name="*" minlevel="Trace" writeTo="f" />
  </rules>
</nlog>

编辑：添加了 App.config 文件

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <configSections>
        <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089">

        </sectionGroup>
    </configSections>

Answer 1

您的网站出现 XML 错误。config/app.config

在 NLog 4.4 中，修复了 NLog 不会崩溃的问题。（参见 bug report），所以更新会修复它。更新到最新版本，建议4.5.10。

Answer 2

我发现错误了！

我找到了这个其中表示在 %localappdata%\companyname\programname...

中创建了 app.config 的副本

我删除了名称中包含该程序名称的所有目录。

一切正常！！

感谢所有帮助，没有它我就找不到解决方案！
