用c反射的惰性泛型类型的调用方法＃

Question

我想调用关闭带反射的_baseInfoService方法if IsValueCreated。我如何用反射来做到这一点？

public static partial class ServiceFactory 
{ 
    private static readonly Lazy<ServiceWrapper<IBaseInfoWcfService>> _baseInfoService = 
     new Lazy<ServiceWrapper<IBaseInfoWcfService>>(CreateWrapper<IBaseInfoWcfService>); 

    public static IBaseInfoWcfService BaseInfoService => _baseInfoService.Value.Instance; 
} 

Answer 1

class ServiceWrapper<T> 
{ 
    public T Instance { get; private set; } 

    public ServiceWrapper(T instance) { 
     Instance = instance; 
    } 

    public void Close() { 

    } 
} 

public interface IBaseInfoWcfService 
{ 

} 

public class BaseInfoWcfServiceImpl : IBaseInfoWcfService 
{ 
    public BaseInfoWcfServiceImpl() { 

    } 
} 

public static partial class ServiceFactory 
{ 
    private static readonly Lazy<ServiceWrapper<IBaseInfoWcfService>> _baseInfoService = 
     new Lazy<ServiceWrapper<IBaseInfoWcfService>>(CreateWrapper<IBaseInfoWcfService>); 

    public static IBaseInfoWcfService BaseInfoService => _baseInfoService.Value.Instance; 

    private static ServiceWrapper<IBaseInfoWcfService> CreateWrapper<T>() where T : IBaseInfoWcfService { 
     return new ServiceWrapper<IBaseInfoWcfService>(new BaseInfoWcfServiceImpl()); 
    } 
} 

static void Main(string[] args) { 
    var baseInfoService = typeof(ServiceFactory).GetField("_baseInfoService", BindingFlags.Static | BindingFlags.NonPublic); 
    var instance = baseInfoService.GetValue(null); 
    var isValueCreated = (bool)instance.GetType().GetProperty("IsValueCreated").GetValue(instance); 

    if (isValueCreated) { 
     var value = instance.GetType().GetProperty("Value").GetValue(instance); 
     var close = (Action)value.GetType().GetMethod("Close").CreateDelegate(typeof(Action), value); 

     close(); 
    } 
}
