}
}
}

(4). Use

1. Add components (InterOP. wmplib). This class library comes with vs. NET and is not added by default.

Method: expand the project folder, right-click reference, add reference, go to the COM component bar, and find add to project.

2. Create a New *. CS file, copy the code, and overwrite it all, and modify the playback file name in the example above.

The statement is as follows: strfilename = @ ".../../sound/mayfall. wav"; // This music file must exist; otherwise, it cannot be played.

3. If this method is called in a different namespace than this class, open the namespace of the class where it is used.

Method: for example, the namespace of this example class should be written as follows: Using Intelligent chess game;

Finally, you can use it. The usage is extremely simple. You can directly call this method:

Sound. Play ("move"); // The parameter customization. It has nothing to do with the underlying method. You can see the swith statement in the above class.
