c# - System.ArgumentException : No member matching data has been found - Unity IOC

Question

在行执行时我的应用程序出现异常

public static void Initialize(Context applicationContext, IUnityContainer diContainer)
{
    diContainer.RegisterType<IAndroidGlobals, AndroidGlobals>(new ContainerControlledLifetimeManager(), new InjectionConstructor(applicationContext));
}

这是AndroidGlobls类

public class AndroidGlobals : IAndroidGlobals
{

    public string ApplicationVersion(string appName)
    {
        return  ApplicationContext.PackageManager.GetPackageInfo(appName, 0).VersionName;
    }
    public Android.Content.Context ApplicationContext
    {
        get { return _applicationContext; }
    }

    private readonly Context _applicationContext;

    public AndroidGlobals(Context applicationContext)
    {
        _applicationContext = applicationContext;
    }
}

以下是异常(exception)。我该如何解决这个问题

我在链接器中使用 Sdk and User Assembly。我该如何解决这个问题？

通过在所有使用的类的顶部使用属性[Android.Runtime.Preserve(AllMembers = true)]解决了此问题。
