WPF OpenFileDialog 一打开“打开文件”对话框程序就退出

Question

在vs2010里面调试是好好的。但是生成安装包安装之后，一点击“打开”菜单，程序就退出了。不知道是什么问题。以前重来没碰到过。一下是“打开”菜单的事件函数。哪位碰到过这样的情况？？？ private void fileMenu_Click(object sender, RoutedEventArgs e) { System.Windows.Forms.OpenFileDialog open = new System.Windows.Forms.OpenFileDialog(); open.Multiselect = false; open.Filter = "Video Files(*.avi;*.rmvb;*.flv;*.mp4)|*.avi;*.rmvb;*.flv;*.mp4|All Files(*.*)|*.*"; //open.ShowDialog(); if (open.ShowDialog() == System.Windows.Forms.DialogResult.OK) { if (null != videoSource && videoSource.IsRunning) { videoSource.Stop(); } if (null == videoSource) { videoSource = new AForge.Video.FFMPEG.VideoFileSource(open.FileName); videoSource.NewFrame += new AForge.Video.NewFrameEventHandler(videoSource_NewFrame); } else { videoSource.Source = open.FileName; } } }
