xamarin - 注销显示警报 xamarin.forms

Question

我一直在尝试允许用户使用 DisplayAlert 确认注销。如果他们单击“否”，它应该保留在他们的个人资料页面中，否则他们应该被重定向回登录页面。我还没有设法完成此操作，如果我单击"is"或“否”，两个选项都会保留在个人资料页面中

public async void LogoutBtn(object sender, EventArgs e)
{
    var answer = await DisplayAlert("Exit", "Do you wan't to exit the App?", "Yes", "No");
    if(answer.Equals("Yes"))
    {
        Settings.FirstName = string.Empty;
        Settings.LastName = string.Empty;
        Settings.Email = string.Empty;
        await Navigation.PushAsync(new MainPage());
    }
    else
    {
        App.Current.MainPage = new Profile();
    }
}

Answer 1

DisplayAlert 返回一个 bool 值(true/false):

var answer = await DisplayAlert("Exit", "Do you wan't to exit the App?", "Yes", "No");
if (answer)
{
    // User choose Yes
}
else
{
    // User choose No
}
