Question

我开发了一个Windows Mobile 6.5应用程序。在我的应用程序相机选项可用，我需要捕获这么多的图像，但在捕获5个图像后，它会抛出异常，如＆＃34; 初始化失败＆＃34;

这是我的代码段。

                CameraCaptureDialog  cameraCapture = new CameraCaptureDialog();
                cameraCapture.Resolution = new Size(240, 320);
                cameraCapture.Owner = null;
                string directoryString = @"\My Documents";

                if (Directory.Exists(directoryString))
                {

                    cameraCapture.InitialDirectory = @"\My Documents\SurveyImages";


                }
                else
                {
                    string activeDir = @"\My Documents\";
                    string newpath = System.IO.Path.Combine(activeDir, "SurveyImages");
                    System.IO.Directory.CreateDirectory(newpath);

                    cameraCapture.InitialDirectory = @"\My Documents\SurveyImages";

                }

                cameraCapture.StillQuality = CameraCaptureStillQuality.High;

                cameraCapture.Mode = CameraCaptureMode.Still;

                if (DialogResult.OK == cameraCapture.ShowDialog())
                {


                 }

我如何解决这个问题。

更改您的代码

CameraCaptureDialog  cameraCapture = new CameraCaptureDialog();
cameraCapture.Resolution = new Size(240, 320);
cameraCapture.Owner = null;
string directoryString = @"\My Documents";
if (Directory.Exists(directoryString))
{
    cameraCapture.InitialDirectory = @"\My Documents\SurveyImages";
}
else
{
    string activeDir = @"\My Documents\";
    string newpath = System.IO.Path.Combine(activeDir, "SurveyImages");
    System.IO.Directory.CreateDirectory(newpath);
    cameraCapture.InitialDirectory = @"\My Documents\SurveyImages";
}
cameraCapture.StillQuality = CameraCaptureStillQuality.High;
cameraCapture.Mode = CameraCaptureMode.Still;
if (DialogResult.OK == cameraCapture.ShowDialog())
{
   ???
}

到

CameraCaptureDialog  cameraCapture = new CameraCaptureDialog();
cameraCapture.Resolution = new Size(240, 320);
cameraCapture.Owner = null;
string directoryString = @"\My Documents";
if (Directory.Exists(directoryString))
{
    cameraCapture.InitialDirectory = @"\My Documents\SurveyImages";
}
else
{
    string activeDir = @"\My Documents\";
    string newpath = System.IO.Path.Combine(activeDir, "SurveyImages");
    System.IO.Directory.CreateDirectory(newpath);
    cameraCapture.InitialDirectory = @"\My Documents\SurveyImages";
}
cameraCapture.StillQuality = CameraCaptureStillQuality.High;
cameraCapture.Mode = CameraCaptureMode.Still;
if (DialogResult.OK == cameraCapture.ShowDialog())
{
   ???
}
cameraCapture.Dispose();
cameraCapture=null;

如果这对您不起作用，请提供更多代码。此更改可确保在您尝试创建新对象之前完全清除cameraCapture对象。
