using Xamarin.Forms;

public class EmailLinkPage : ContentPage
{
    public EmailLinkPage()
    {
        var emailLinkLabel = new LinkLabel
        {
            Text = "点击这里发送电子邮件",
            FontSize = Device.GetNamedSize(NamedSize.Medium, typeof(Label)),
            HorizontalOptions = LayoutOptions.Center,
            VerticalOptions = LayoutOptions.Center
        };

        emailLinkLabel.LinkTapped += async (sender, e) =>
        {
            var email = "example@example.com";
            var mailtoLink = $"mailto:{email}";
            await Application.Current.MainPage.Navigation.PushAsync(new WebViewPage(mailtoLink));
        };

        Content = new StackLayout
        {

public class WebViewPage : ContentPage
{
    public WebViewPage(string url)

            Source = new UrlWebViewSource { Url = url },
            VerticalOptions = LayoutOptions.FillAndExpand
        };

        Content = new StackLayout
