You can use DirectShow Editing Services (DES) to do it. 您可以使用DirectShow编辑服务（DES）来完成。 DirectShowLib should provide DES support in C#. DirectShowLib应该在C＃中提供DES支持。 Using it, create a timeline with video group (1 track) and audio group (several tracks if you need to overlay/mix some audios, ie hear more than one at a time). 使用它，创建一个具有视频组（1条轨道）和音频组（如果需要叠加/混合一些音频，即一次听到多个音频）的时间线。 Place your video and audio files on the timeline in desired positions. 将视频和音频文件放在时间轴上的所需位置。 Then tell DES to create a DirectShow graph and you'll get one video and one audio output pin. 然后，告诉DES创建DirectShow图，您将获得一个视频和一个音频输出引脚。 Connect them to ASF writer to save result to WMV. 将它们连接到ASF writer，以将结果保存到WMV。
