学习monodevelop并且无法让杂物盒出现

Question

我正在monodevelop和学习c#....我试图让消息框出现,但我无法让它正常运行...

这是我的代码:

using System;  
using Gtk;  
using GtkSharp;  

public partial class MainWindow : Gtk.Window  
{
    public MainWindow () : base(Gtk.WindowType.Toplevel)  
    {  
        Build ();  
    }  

    protected void OnDeleteEvent (object sender, DeleteEventArgs a)
    {
        Application.Quit ();
        a.RetVal = true;
    }
    protected virtual void OnButton11ResizeChecked (object sender, System.EventArgs e)
    {
        System.Windows.Forms.MessageBox.Show("Hello World Again!!");
    }

}

我错过了什么？

您不能混合使用GTK#和System.Windows.Forms UI工具包.您需要使用GTK对话框,如下所示:

void ShowMessage (Window parent, string title, string message)
{
    Dialog dialog = null;
    try {
        dialog = new Dialog (title, parent,
            DialogFlags.DestroyWithParent | DialogFlags.Modal,
            ResponseType.Ok);
        dialog.VBox.Add (new Label (message));
        dialog.ShowAll ();

        dialog.Run ();
    } finally {
        if (dialog != null)
            dialog.Destroy ();
    }
}

另见这个问题.
