所以我是 Xamarin Forms 的新手，我发现了两种添加按钮的方法：

1.在.xaml文件中声明按钮

 <!--  <Button Text="Click Me!"
      Clicked="OnButtonClicked" VerticalOptions="CenterAndExpand" />-->

和 .xaml.cs 文件

 public void OnButtonClicked(object sender, EventArgs args)
     {
         count++;

         label.Text =
             String.Format("{0} click{1}!", count, count == 1 ? "" : "s");

2. 仅在 .xaml.cs 文件中声明按钮

   using System;
   using Xamarin.Forms;
   
   namespace FormsGallery
   {
       class ButtonDemoPage : ContentPage
       {
           Label label;
           int clickTotal = 0;
   
           public ButtonDemoPage()
           {
               Label header = new Label
               {
                   Text = "Button",
                   Font = Font.BoldSystemFontOfSize(50),
                   HorizontalOptions = LayoutOptions.Center
               };
   
               Button button = new Button …
