调用MediaLibrary.SavePicture()时出现System.ArgumentException

Question

我的代码看起来像这样:

String filename = Utils.GetNextFilename();
MediaLibrary library = new MediaLibrary();
library.SavePicture(filename, corrected_image);

在SavePicture()通话中,我得到以下内容:

Microsoft.Xna.Framework.dll中出现未处理的"System.ArgumentException"类型异常

附加信息:价值不在预期范围内.

但我不确定为什么.

Answer 1

好的,我明白了.我必须重置流:

String filename = Utils.GetNextFilename();
MediaLibrary library = new MediaLibrary();
corrected_image.Seek(0, 0);                      // <-- The fix.
library.SavePicture(filename, corrected_image);
