内置发射器＆amp; WP7 / WP8中的选择器体验允许轻松捕获照片或从手机的图像库中检索照片。使用内置照片选择器是获得默认用户体验的最简单方法。

您可以阅读有关允许在MSDN @ How to use the camera capture task for Windows Phone上快速捕获图像的CameraCaptureTask

您可以阅读有关允许从MSDN @ How to use the photo chooser task for Windows Phone上的手机照片库中检索图像的PhotChooserTask

如果您想构建更复杂的图像处理和相机捕捉应用程序，您可以在诺基亚的Advanced photo capturing文章中了解新的WP8 API。

       // Try the following steps

       private readonly CameraCaptureTask _cameraCaptureTask; // Declare CameraCaptureTask

       if (null == _cameraCaptureTask) _cameraCaptureTask = new CameraCaptureTask();
        _cameraCaptureTask.Completed += PhotoSelectionTaskCompleted;

      // In the completed event 

       void PhotoSelectionTaskCompleted(object sender, PhotoResult e)
       {
            if (null != e.ChosenPhoto && e.TaskResult == TaskResult.OK)
            {
                var image = new BitmapImage();
                image.SetSource(e.ChosenPhoto);
                SaveImageToIsolatedStorage(image,"Image1.jpg");

            }
       }

      public void SaveImageToIsolatedStorage(BitmapImage image, string fileName)
      {
        using (var isolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
        {
            if (isolatedStorage.FileExists(fileName))
                isolatedStorage.DeleteFile(fileName);

            var fileStream = isolatedStorage.CreateFile(fileName);
            if (image != null)
            {
                var wb = new WriteableBitmap(image);
                wb.SaveJpeg(fileStream, wb.PixelWidth, wb.PixelHeight, 0, 100);
            }
            fileStream.Close();
        }
    }
