(1). Description
For a music playing class, you can use copy directly.
It can be used for self-compiled games and other places where music needs to be played. You only need to give it a file name.
OK. For details, refer to the following code.
(2). Steps
Using system;
// Using system. drawing;
Using system. collections;
Using system. componentmodel;
// Using system. Windows. forms;
// Using system. Data;
Using system. runtime. interopservices;
Namespace chess game
{
///

/// Used to play music

Internal class helpers
{
[Flags]
Public Enum playsoundflags: int
{
Snd_sync = 0x0000,/* play synchronously (default) * // synchronize
Snd_async = 0x0001,/* Play asynchronously * // asynchronous
Snd_nodefault = 0x0002,/* silence (! Default) if sound not found */
Snd_memory = 0x0004,/* pszsound points to a memory file */
Snd_loop = 0x0008,/* loop the sound until next sndplaysound */
Snd_nostop = 0x0010,/* Don ???? T stop any currently playing sound */
Snd_nowait = 0x00002000,/* Don ???? T wait if the driver is busy */
Snd_alias = 0x00010000,/* name is a registry alias */
Snd_alias_id = 0x00110000,/* alias is a predefined ID */
Snd_filename = 0x00020000,/* name is file name */
Snd_resource = 0x00040004/* Name Is Resource Name or atom */
}
[Dllimport ("winmm")]
Public static extern bool playsound (string szsound, intptr hmod, playsoundflags flags );
}
Public class sound
{
Public static void play (string strfilename)
{
// Helpers. playsound (strfilename, intptr. Zero, helpers. playsoundflags. snd_filename | helpers. playsoundflags. snd_async );
Switch (strfilename)
{
Case "start": strfilename = @ ".../sound/start. wav"; break;
Case "back": strfilename = @ ".../sound/back. wav"; break;
Case "fall": strfilename = @ ".../../sound/fall. wav"; break;
Case "Huiqi": strfilename = @ ".../../sound/Huiqi. wav"; break;
Case "huiqiend": strfilename = @ ".../../sound/huiqiend. wav"; break;
Case "Jiangjun": strfilename = @ ".../../sound/Jiangjun. wav"; break;
Case "kill": strfilename = @ ".../../sound/kill. wav"; break;
Case "win": strfilename = @ ".../sound/win. wav"; break;
Case "move": strfilename = @ ".../sound/move. wav"; break;
Case "hold": strfilename = @ ".../sound/hold. wav"; break;
Case "no": strfilename = @ ".../sound/No. wav"; break;
Case "popup": strfilename = @ ".../../sound/Popup. wav"; break;
Case "mayfall": strfilename = @ ".../../sound/mayfall. wav"; break;
}
Helpers. playsound (strfilename, intptr. Zero, helpers. playsoundflags. snd_filename | helpers. playsoundflags. snd_async); // call the DLL method to play music.
}
}
}
(3). 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.
This is the statement: 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.
