Xceed.Wpf.Toolkit.MessageBox mbox = new Xceed.Wpf.Toolkit.MessageBox();
System.Windows.Style style = new System.Windows.Style(typeof(System.Windows.Controls.Button));
style.Setters.Add( new System.Windows.Setter(System.Windows.Controls.Button.ForegroundProperty, Brushes.DarkGreen));
mbox.OkButtonStyle = style;
我遇到了错误
System.Windows.Markup.XamlParseException: ''System.Drawing.SolidBrush' is not a valid value for the 'System.Windows.Documents.TextElement.Foreground' property on a Setter.'
