目前在尝试将我的 Xamarin 应用程序运行到我的 iPhone 直播播放器时遇到此错误。
"AppDelegate.cs(1,1): error: The type or namespace name 'App' could not be found (are you missing a using directive or an assembly reference?)"
我的解决方案构建没有错误,所以有点卡住了。 直到我更新到最新更新后才出现这些错误。非常感谢任何帮助。
App.xaml.cs:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using COCApp;
using Xamarin.Forms;
namespace COCApp
{
public partial class App : Application
{
public App()
{
InitializeComponent();
MainPage = new NavigationPage(new MainPage());
}
protected override void OnStart()
{
// Handle when your app starts
}
protected override void OnSleep()
{
// Handle when your app sleeps
}
protected override void OnResume()
{
// Handle when your app resumes
}
}
}
AppDelegate.cs
using System;
using System.Collections.Generic;
using System.Linq;
using COCApp;
using Foundation;
using UIKit;
namespace COCApp.iOS
{
// The UIApplicationDelegate for the application. This class is responsible for launching the
// User Interface of the application, as well as listening (and optionally responding) to
// application events from iOS.
[Register("AppDelegate")]
public partial class AppDelegate : global::Xamarin.Forms.Platform.iOS.FormsApplicationDelegate
{
//
// This method is invoked when the application has loaded and is ready to run. In this
// method you should instantiate the window, load the UI into it and then make the window
// visible.
//
// You have 17 seconds to return from this method, or iOS will terminate your application.
//
public override bool FinishedLaunching(UIApplication app, NSDictionary options)
{
global::Xamarin.Forms.Forms.Init();
LoadApplication(new App());
return base.FinishedLaunching(app, options);
}
}
}
最佳答案
我在 Android 和 iOS 上遇到了类似的问题,但我的可以正常构建和运行,只是两个项目的 App 下都有红色下划线。
我通过右键单击 Android References->Add Reference->Projects 然后取消选中已包含的共享项目单击 OK 来修复它。 然后我重新添加了共享项目并修复了错误。
请注意,在最新的 Visual Studio 版本(现在是 .Net Standard)中启动 Xamarin.Forms 项目时,不再需要 PCL。
