Note:

1. Set Registe. aspx to the root directory. (The Voice function cannot be used if it is placed under a folder. The reason is not clear)

2. The files stored in the sound folder are: begin.mp3?end=and sound_play.swf.

CodeVoice. aspx in the root directory (delete all Page code and leave only header files)

The cs code is as follows:

Protected void Page_Load (object sender, EventArgs e)
{
// Read and verify the code to generate the MP3 package.
Response. ContentType = "audio/mpeg ";
Response. WriteFile ("Sound/begin.pdf ");
String checkCode = "";
If (Session ["CheckCode"]! = Null)
{
CheckCode = Session ["CheckCode"]. ToString ();
}
If (checkCode. Length> 0)
For (int I = 0; I <checkCode. Length; I ++)
{
Response. WriteFile ("Sound/" + checkCode [I] + ". mp3 ");
}
Response. WriteFile ("Sound/Endpoint ");
}
