从SD卡中读取.mp4，.jpg等. [英] Read .mp4, .jpg, etc. etc. from the SD Card

问题描述

我正在尝试从SD卡中读取某个应用的.mp4文件，但似乎找不到它们.我发现包含它们的文件夹很好，但是当我调用GetFilesAsync()函数时，什么也没有返回.我已将.mp4列为受支持的 WMAppManifest.xml中的文件类型.

I'm trying to read .mp4 files for an app off of the sd card but it doesn't seem to find them.  I find the folder that contains them just fine but when I call the GetFilesAsync() function nothing is returned.  I've listed the .mp4 as a supported file type in the WMAppManifest.xml.

还有什么要做?

如果将文件重命名为其他名称(例如扩展名为.test1并将test1注册到WMAppManifest)，则可以通过查看文件是否可见来确认这一点.

You can confirm this by seeing if the files become visible if you rename your files to something else, say with a .test1 extension and registering test1 to your WMAppManifest.
