问题描述

我正在从事monodevelop的工作，正在学习c#.我试图显示一个消息框，但无法使其正常运行...

I am working in monodevelop and learning c#....I am trying to get a message box to appear but I can't get it to function correctly ...

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!!");
    }

}

我想念什么?

推荐答案

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:

You cannot mix the GTK# and System.Windows.Forms UI toolkits. You need to use a GTK dialog, something like this:

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 ();
    }
}
