Question

我正在尝试使用：我的Xamarin.Forms应用程序上的表单的ZXing.Net.Mobile https://components.xamarin.com/gettingstarted/zxing.net.mobile.forms

namespace MnakabAlshabaViewBook.Droid
{
    [Activity ( Icon = "@drawable/icon", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
    [assembly: UsesPermission(Manifest.Permission.Flashlight)]
    public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsApplicationActivity
    {

        protected override void OnCreate (Bundle bundle)
        {
            base.OnCreate (bundle);

            global::Xamarin.Forms.Forms.Init (this, bundle);

            ZXing.Net.Mobile.Forms.Android.Platform.Init();

            LoadApplication(new App());

        }

我收到以下错误：

＆＃39;组装＆＃39;不是有效的属性位置声明。此声明的有效属性位置是＆＃39;类型＆＃39 ;.此块中的所有属性都将被忽略。

我应该放在哪里： [assembly: UsesPermission (Android.Manifest.Permission.Flashlight)] ???

您必须将程序集属性放在命名空间之上，因此重新排列它：

[assembly: UsesPermission(Manifest.Permission.Flashlight)]
namespace MnakabAlshabaViewBook.Droid
{
    [Activity ( Icon = "@drawable/icon", MainLauncher = true, ConfigurationChanges = ConfigChanges.ScreenSize | ConfigChanges.Orientation)]
    public class MainActivity : global::Xamarin.Forms.Platform.Android.FormsApplicationActivity
    {
       //... Rest of code is here ...

哪个有效的＆＃39;汇编＆＃39;属性位置？
