当前上下文中不存在C＃“控件”

Question

错误

在我的应用程序中，我尝试使用“ Controls.Add”，但是Visual Studio不断给我错误：

“错误1名称'控件'在当前上下文C：\\ Users \\ Admin \\ Desktop \\ Demo \\ Demo \\ MainWindow.xaml.cs 42 13演示中不存在”

    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
        }



        private void Button_Click(object sender, RoutedEventArgs e)
        {
            Window1 window = new Window1();
            Button button = new Button();

            window.WindowStartupLocation = WindowStartupLocation.CenterScreen;
            button.Content = "New Button";
            button.Visibility = Visibility.Visible;
            button.Height = 50;
            button.Width = 200;


            Controls.add(button); <-- ERROR IS FOUND HERE


            window.Show();


        }
    }
}

我正在使用WPF，来自WinForms。 任何建议表示赞赏，谢谢。

Answer 1

您需要执行以下操作：

var window = new Window1();

var stackPanel = new StackPanel { Orientation = Orientation.Vertical };

Button button = new Button();
button.Content = "New Button";
button.Visibility = Visibility.Visible;
button.Height = 50;
button.Width = 200;

stackPanel.Children.Add(button);

window.Content = stackPanel;
window.Show();

虽然，我建议在XAML中定义所有UI组件，并阅读MVVM模式。

Answer 2

 <StackPanel Name=“splMain“>
<Button Name=“btnAddMore“ Click=“btnAddMore_Click“>Add Another</Button>

同样在按钮上单击：

System.Windows.Controls.Button newBtn = new Button();
  newBtn.Content = “A New Button”;
  splMain.Children.Add(newBtn);

Answer 3

 Button SaveButton = new Button();
 SaveButton.Name = "Save";
 SaveButton.Content = "Save";
 Grid1.Children.Add(SaveButton);
