Question

这是我的代码：

using Microsoft.Xna.Framework;
using Microsoft.Xna.Framework.Audio;
using System.IO;

Stream stream = TitleContainer.OpenStream("sounds/BEEP.WAV");
SoundEffect effect = SoundEffect.FromStream(stream);
FrameworkDispatcher.Update();
effect.Play();

我在行“SoundEffect effect = SoundEffect.FromStream（stream）”中得到InvalidOperationException 任何想法如何解决它？

根据MSDN documentation，stream指向的文件有非常具体的要求：

The Stream object must point to the head of a valid PCM wave file. Also, this wave file must be in the RIFF bitstream format.

The audio format has the following restrictions:

    Must be a PCM wave file
    Can only be mono or stereo
    Must be 8 or 16 bit
    Sample rate must be between 8,000 Hz and 48,000 Hz
