C#Windows服务无法将GetSection()与自定义ConfigurationSection一起使用

我在尝试使用自定义应用程序时遇到异常。我的Windows服务中的配置节。我已经成功地在其他应用程序中编写了自定义部分,所以我非常确定我的机制是正确的,并且当涉及到Windows服务时,会发生一些事情。我可以包括应用程序。如果需要,配置Xml。

第一次尝试

我在C#窗口服务构造函数中有以下代码:

int systemErrorWindowSeconds = 
    ServiceSettings.Current.ExceptionHandling.SystemErrorWindowSeconds;

ServiceSettings(重要位)如下:

public class ServiceSettings : ConfigurationSection
{
    private static ServiceSettings settings;

    static ServiceSettings()
    {
        var config = 
            ConfigurationManager.OpenExeConfiguration( ConfigurationUserLevel.None );

        settings = config.GetSection( "serviceSettings" ) as ServiceSettings;
    }

    public static ServiceSettings Current { get { return settings;  } }

ServiceSettings.Current

Application: BTR.Evolution.Service.exe

Description: The process was terminated due to an unhandled exception.

    at BTR.Evolution.Service.ServiceSettings.get_Current()
    at BTR.Evolution.Service.EvolutionService..ctor(System.String[])
    at BTR.Evolution.Service.Program.Main(System.String[])

第二次尝试:

我将ServiceSettings类更改为使用GetSection,如下所示:

static ServiceSettings()
{
    settings = ConfigurationManager.GetSection( "serviceSettings" ) as ServiceSettings;
}

我得到了以下异常(基本上与上面相同,但使用ConfigurationManager和少量GetSectionRecursive调用)

Application: BTR.Evolution.Service.exe
Framework Version: v4.0.30319
Description: The process was terminated due to an unhandled exception.

    at BTR.Evolution.Service.ServiceSettings.get_Current()
    at BTR.Evolution.Service.EvolutionService..ctor(System.String[])
    at BTR.Evolution.Service.Program.Main(System.String[])

第三次尝试

我更改了ServiceSettings构造函数以尝试:

var customConfig = 
    ConfigurationManager.OpenExeConfiguration( AppDomain.CurrentDomain.SetupInformation.ConfigurationFile );

settings = customConfig.GetSection( "serviceSettings" ) as ServiceSettings;

我得到了以下例外。基本上,设置变量被赋值为null(没有“配置管理器”异常),因此使用该对象的调用者得到一个null异常。

Application: BTR.Evolution.Service.exe
Framework Version: v4.0.30319 
Description: The process was terminated due to an unhandled exception. 
Exception Info: System.NullReferenceException 
    at BTR.Evolution.Service.EvolutionService..ctor(System.String[]) 
    at BTR.Evolution.Service.Program.Main(System.String[])

最后一次尝试

我更改了ServiceSettings构造函数以尝试使用程序集解析程序。

Func<object, ResolveEventArgs, System.Reflection.Assembly> getAssembly = 
    ( sender, args ) => typeof( ServiceSettings ).Assembly;

var resolveHandler = new System.ResolveEventHandler( getAssembly );

AppDomain.CurrentDomain.AssemblyResolve += resolveHandler;

var customConfig = 
    ConfigurationManager.OpenExeConfiguration( AppDomain.CurrentDomain.SetupInformation.ConfigurationFile );

settings = customConfig.GetSection( "serviceSettings" ) as ServiceSettings;

AppDomain.CurrentDomain.AssemblyResolve -= resolveHandler;

但我得到了与第三次尝试完全相同的结果。

如能就如何开展这项工作提出任何建议,我们将不胜感激。如果我需要提供任何其他信息,请告诉我。
