如何播放存储在数据库Access中的声音文件

问题描述

你好

请给我可以让我读取存储在数据库中的file.wav("alarme.wav")的代码，我尝试了以下代码:

Hello

Please can you give me the code that allows me to read a file.wav ("alarme.wav") stored in a database, I tried the following code:

private void button1_Click (object sender, EventArgs e)
{

OdbcConnection cn = new OdbcConnection ("DSN = cp1");
cn.Open ();
OdbcCommand cmd1 = new OdbcCommand ("select path from WHERE Code Alarm alarm = 32 ", cn);
cmd1.Connection = cn;
fileName = cmd1.ToString ();
WaveOut wave = new ();
wave.DeviceNumber = 0;
playSound (0);

但这给了我以下错误:
找不到文件"C:\ Users \ wafa \ Documents \ Visual Studio 2010 \ Projects \ ALARMED \ ALARMED \ bin \ Debug \ System.Data.Odbc.OdbcCommand"."
在此行:
"waveReader =新的NAudio.Wave.WaveFileReader(fileName)；"在我的"playSound"函数中:

But that gave me the following error:
"Could not find file ''C: \ Users \ wafa \ Documents \ Visual Studio 2010 \ Projects \ ALARMED \ ALARMED \ bin \ Debug \ System.Data.Odbc.OdbcCommand''."
At the line:
"waveReader = new NAudio.Wave.WaveFileReader (fileName);" in my "playSound" function:

public void PlaySound (int deviceNumber)
{
disposeWave ();// stop previous sounds Before Starting
waveReader = new NAudio.Wave.WaveFileReader (fileName);
var waveOut NAudio.Wave.WaveOut = new ();
waveOut.DeviceNumber = deviceNumber;
var output = waveOut;
output.Init (waveReader);
output.Play ();
}

提前谢谢您.
美好的一天:)

Thank you in advance.
Good day:)
