SetContentView()问题

Question

我一直在跟随这教程，让Xamarin制作一个android应用程序，出于某种原因，编译器给出了这个错误

Error   CS1061  'Resources' does not contain a definition for 'layout' and no accessible extension method 'layout' accepting a first argument of type 'Resources' could be found (are you missing a using directive or an assembly reference?)  XamarinHelloWorld

用这个代码

using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;

namespace HelloWorld
{
    public class MainActivity : Activity
    {
        protected override void OnCreate (Bundle bundle)
        {
            base.OnCreate(bundle);
            SetContentView(Resources.layout.main);
        }
    }
} 

然而，参考资料中有一个布局文件夹

我相信你的代码中有错误。

而不是：

namespace HelloWorld
{
public class MainActivity : Activity
{
    protected override void OnCreate (Bundle bundle)
    {
        base.OnCreate(bundle);
        SetContentView(**Resources**.layout.main);
    }
  }
} 

它应该是：

namespace HelloWorld
{
public class MainActivity : Activity
{
    protected override void OnCreate (Bundle bundle)
    {
        base.OnCreate(bundle);
        SetContentView(**Resource**.layout.main);
    }
  }
}
