Question

我有一些问题要从媒体库中获取图像，我想知道是否有任何选项可以获取或自动过滤库中的某些图像。例如，假设我有像1.jpg，2.jpg，3.jpg ........等图像。我从媒体库获取图像并将所有图像保存在隔离存储中，所以我想只获取某些图像，而不是所有来自媒体库的图像，这是我的代码

 using (MediaLibrary mediaLibrary = new MediaLibrary())  
{
     PictureCollection AllScreenShot = mediaLibrary.Pictures;
     foreach (Picture picture in AllScreenShot)
     {
       using (IsolatedStorageFile storage = IsolatedStorageFile.GetUserStoreForApplication())
           {
              if (!storage.DirectoryExists("SavedImg"))
                            storage.CreateDirectory("SavedImg");

                        if (storage.FileExists("SavedImg" + "\\" + picture.Name))
                            storage.DeleteFile("SavedImg" + "\\" + picture.Name);
                        using (IsolatedStorageFileStream file = storage.CreateFile("SavedImg" + "\\" + picture.Name))
                            picture.GetImage().CopyTo(file);
            }
       }
 }

这将有助于

var picture = media.Pictures.FirstOrLast(p => p.Name.Contains("1.jpg"));

        if (picture == null)
        {
            // 1.jpg not found
        }
        else
        {
           //1.jpg found
        }
