如何在Xamarin Android上使用InvokePattern？

using Android.AccessibilityServices;
using Android.Views.Accessibility;

public class MainActivity : Activity
{
    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        SetContentView(Resource.Layout.activity_main);

        Button button = FindViewById<Button>(Resource.Id.myButton);
        button.Click += Button_Click;
    }

    private void Button_Click(object sender, EventArgs e)
    {
        AccessibilityManager accessibilityManager = (AccessibilityManager)GetSystemService(Context.AccessibilityService);
        AccessibilityNodeInfo rootNode = accessibilityManager.GetAccessibilityServiceInfo().RootInActiveWindow;

        if (rootNode != null)
        {
            List<AccessibilityNodeInfo> nodes = rootNode.FindAccessibilityNodeInfosByViewId("com.example.app:id/myButton");

            if (nodes.Count > 0)
            {
                AccessibilityNodeInfo buttonNode = nodes[0];
                buttonNode.PerformAction(AccessibilityNodeInfo.ActionClick);
            }
        }
    }
}
