PPC 调用摄像头 出错

[destinyC]

            try
            {
                CameraCaptureDialog camera = new CameraCaptureDialog();

                camera.Owner = new Control();
                camera.Title = "test";
                camera.Mode = CameraCaptureMode.Still;
                camera.StillQuality = CameraCaptureStillQuality.High;
                camera.Resolution = new Size(100, 100);

                string path = System.IO.Path.GetDirectoryName(Assembly.GetExecutingAssembly().ManifestModule.FullyQualifiedName) + "\\Photo\\";

                if (!File.Exists(path))
                {
                    Directory.CreateDirectory(path);
                }

                camera.InitialDirectory = path;

                camera.DefaultFileName = "test_photo";

                if (camera.ShowDialog() == DialogResult.OK)
                {
                    photoPath = camera.FileName;
                }
            }
            catch (Exception Err)
            {
                MessageBox.Show("调用照相机出错，请重试" + Err.Message);
            }

主要代码就在这，执行到
if (camera.ShowDialog() == DialogResult.OK)
{
photoPath = camera.FileName;
}
就抛出异常

分不多了 高手帮帮忙看一下啊
