Question

我使用以下内容在应用中显示GTK文件选择器对话框，否则不会将GTK用于其他任何内容。

Gtk.FileChooserDialog fc =
    new Gtk.FileChooserDialog(openParams.Title,
        null,
        FileChooserAction.Open,
        "Cancel", ResponseType.Cancel,
        "Open", ResponseType.Accept);

这基本上直接来自http://docs.go-mono.com/index.aspx?link=T%3aGtk.FileChooserDialog的示例。使用gtk-sharp 2.0可以正常工作，但是当我切换到gtk-sharp 3.0时，我得到了这个：

(mono:30587): GLib-GObject-WARNING **: cannot register existing type 'GtkWidget'
(mono:30587): GLib-GObject-WARNING **: cannot add class private field to invalid type '<invalid>'
(mono:30587): GLib-GObject-WARNING **: cannot add private field to invalid (non-instantiatable) type '<invalid>'

(mono:30587): GLib-GObject-WARNING **: cannot add private field to invalid (non-instantiatable) type '<invalid>'

我所做的搜索表明＆＃34;无法注册现有类型＆＃34;混合库版本时会发生一些事情。我确保我的程序集引用指向gtk及其所有相关库（atk，gio，glib）的3.0版本，但它仍然在发生。我怎么能弄清楚什么是错的？
