推荐答案

当前有一种方法可以流式传输文件.

Currently there is a way over streaming the file.

首先，我们需要一个始终应有的地方

First of all, we need a place where it should be always possible

        string streamPath = Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) + @"\";

下一步是MediaPlayer的实例

Next Step an Instance of the MediaPlayer

    WindowsMediaPlayer wmp = new WindowsMediaPlayer();

然后，我们需要流式传输汇编资源

Then we need to stream the Assembly Resource

    Stream stream = Assembly.GetExecutingAssembly().GetManifestResourceStream("Smartis.Resources.Natur.wmv");

    using (Stream output = new FileStream (streamPath + "mediafile.avi", FileMode.Create))
    {
        byte[] buffer = new byte[32*1024];
        int read;

        while ( (read= stream.Read(buffer, 0, buffer.Length)) > 0)
        {
            output.Write(buffer, 0, read);
        }
    }

最后，我们应该能够加载文件了.

Finally we should be able to load the file.

    wmp.URL = streamPath + "mediafile.avi";
    wmp.controls.play();

播放后，别忘了清除文件夹:

After playing don't forget to clear the folder:

    File.Delete(streamPath + "mediafile.avi");
