如何打開一個網頁，點擊一個按鈕在xamarin表格中

Question

我有一個名爲HomePage的文件，名爲HomePage，它接受用戶的eURL內容。

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 

using Xamarin.Forms; 

namespace zaposta_angelar 
{ 
    public class HomePage : ContentPage 
    { 
     Label lTitle; 
     Entry eURL; 
     Button bButton; 

     public HomePage() 
     { 
      lTitle = new Label 
      { 
       Text = "WELCOME", 
       HorizontalOptions = LayoutOptions.Center, 
       FontAttributes = Font.SystemFontOfSize(25, FontAttributes.Bold).FontAttributes, 
       FontSize = Font.SystemFontOfSize(25, FontAttributes.Bold).FontSize, 
       //WidthRequest = 200, 
       HeightRequest = 100 
      }; 

      eURL = new Entry { Placeholder = "Enter Site URL", }; 

      bButton = new Button { Text = "ENTER", }; 
      bButton.Clicked += bButton_Clicked; 

      this.Content = new StackLayout 
      { 
       Children = { 
        lTitle, eURL, bButton 
       } 
      }; 
     } 

     void bButton_Clicked(object sender, EventArgs e) 
     { 
      if (String.IsNullOrEmpty(eURL.Text)) { DisplayAlert("URL", "Your URL is Empty", "OK"); } 
      else 
      { 
       SitePage.LoadRequest(new SitePage(eURL))); 
      } 
     } 
    } 
} 

，並從按鈕bButton的點擊打開EURL和網站加載到到名爲SitePage

using System; 
using System.Collections.Generic; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 

using Xamarin.Forms; 

namespace zaposta_angelar 
{ 
    public class SitePage : NavigationPage 
    { 
     private Entry eURL; 

     public SitePage() 
     { 

     } 

     public SitePage(Entry eURL) 
     { 
      // TODO: Complete member initialization 
      this.eURL = eURL; 
     } 

     internal static void LoadRequest(SitePage sitePage) 
     { 
      throw new NotImplementedException(); 
     } 
    } 
} 

代碼不起作用另一個頁面，任何出路

Answer 1

嗯，我我不知道你打算往哪個方向走，但你可以通過

1. INTE打開網頁rnally使用的WebView

2. 使用Device.OpenUri
