Question

下面列出了同样的问题 The key 'UserID' does not exist in the appSettings configuration section，但遗憾的是，在我的案例中，没有一个答案有效。一切都工作正常，我检查了一切，当我再次打开解决方案时，它开始崩溃在上面。我找不到任何我做错的提示。有什么想法吗？

<configuration>
    <configSections>
        <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
            <section name="SMS.My.MySettings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77b444444e089" requirePermission="false" />
        </sectionGroup>
    </configSections>
    <appSettings>
      <add key="URI" value="http://123.123.123.57:8080/smsxml/collector"/>
      <add key="Provider" value="220"/>
      <add key="LongCode" value="+3"/>
      <add key="DBServer" value="APPS"/>
      <add key="DBUsername" value="sms"/>
      <add key="DBPassword" value="sms1"/>
      <add key="Database" value="SMSService"/>
      <add key="Pooling" value="True"/>
      <add key="PoolMax" value="50"/>
      <add key="PoolInit" value="5"/>
      <add key="DBPollInterval" value="5"/>      
    </appSettings>

Answer 1

您是如何开始服务的？确保运行服务的文件夹中的appname.exe.config文件具有相同的appSettings。

Answer 2

尝试将<appSettings></appSettings>从app.config复制到bin / Debug / appname.exe.config文件，就像构建/编译时一样，VS.NET复制并重命名app.config（到bin / Debug） /appname.exe.config）到bin文件夹。

我的Windows服务因“appSettings配置部分中不存在密钥”而崩溃
