如何使用C#拍照后自动关闭CameraCaptureDialog对话框

我正在做一项工作，在 Windows Mobile 6.5 和 .net Compact Framework 2.0 下扫描条形码并获取其背后的信息，使用 CameraCaptureDialog 类从手机摄像头捕获图片，这是我的代码：

        CameraCaptureDialog cameraCaptureDialog = new CameraCaptureDialog();
        cameraCaptureDialog.Owner = this;
        cameraCaptureDialog.Title = "";
        cameraCaptureDialog.Mode = CameraCaptureMode.Still;
        cameraCaptureDialog.InitialDirectory = dir;
        cameraCaptureDialog.Resolution = new System.Drawing.Size(640, 480);
        cameraCaptureDialog.DefaultFileName = "CodeBar.jpg";

        if (cameraCaptureDialog.ShowDialog() == DialogResult.OK && cameraCaptureDialog.FileName.Length > 0)
        {
            curFileName = cameraCaptureDialog.FileName;
            cameraCaptureDialog.Dispose();
        }

        //deal with CodeBar.jpg

问题是，在我的代码期间运行时，我必须按cameraCaptureDialog上的捕获按钮，然后按后退按钮返回到我的程序来处理捕获的文件，此操作需要按2个按钮，为了用户方便，我希望cameraCaptureDialog在之后自动关闭用户按下了捕获按钮，该怎么办？据我所知，当调用 ShowDialog() 方法时，cameraCaptureDialog 不会返回，直到对话框上显示后退按钮，因此在手动关闭cameraCaptureDialog 和 ShowDialog() 方法返回 DialogResult.OK 之前我什么也做不了

I am doing a work that scans the barcode and gets the information behind it under windows mobile 6.5 and .net compact framework 2.0, using CameraCaptureDialog class to capture a picture from the phone camera, this is my code:

        CameraCaptureDialog cameraCaptureDialog = new CameraCaptureDialog();
        cameraCaptureDialog.Owner = this;
        cameraCaptureDialog.Title = "";
        cameraCaptureDialog.Mode = CameraCaptureMode.Still;
        cameraCaptureDialog.InitialDirectory = dir;
        cameraCaptureDialog.Resolution = new System.Drawing.Size(640, 480);
        cameraCaptureDialog.DefaultFileName = "CodeBar.jpg";

        if (cameraCaptureDialog.ShowDialog() == DialogResult.OK && cameraCaptureDialog.FileName.Length > 0)
        {
            curFileName = cameraCaptureDialog.FileName;
            cameraCaptureDialog.Dispose();
        }

        //deal with CodeBar.jpg

the question is, during my code running, I have to press the capture button on the cameraCaptureDialog, then press the back button to return to my program to deal with the captured file, this operation needs to press 2 buttons, for user convenience, I want the cameraCaptureDialog to close automatically after the user pressed the capture button, how can this be done? as I know, when ShowDialog() method is called, cameraCaptureDialog won't return until the back button shown on the dialog, so I could do nothing before manually close the cameraCaptureDialog and the ShowDialog() method returned DialogResult.OK
