Play MP3 files using C#.
Goals:

This project is used to play the mp3 files using c#.


Steps:

1) Create a c# windows application.

2) create two textboxes and two button controls.

3) copy the following code.

private string PlayCommand;
private bool isOpen;

[DllImport("winmm.dll")]
private static extern long mciSendString(
string strCommand,
StringBuilder strReturn,
int iReturnLength,
IntPtr oCallback);



private void btnselectfile_Click(object sender, EventArgs e)
{

this.openFileDialog1.Filter = "MP3(*.mp3)|*.mp3| Widows File (*.wmv)|*.wmv";
if (this.openFileDialog1.ShowDialog() == DialogResult.OK)
{
txtmediafile.Text = this.openFileDialog1.FileName.ToString();
OpenMediaFile(txtmediafile.Text.ToString());

//File
string strFilePro = openFileDialog1.FileName;
FileInfo oFileInfo = new FileInfo(strFilePro);

//Find file size
txtfilesize.Text = oFileInfo.Length.ToString();

//File Created date
DateTime dtCreationTime = oFileInfo.CreationTime;
txtfilecrdate.Text = dtCreationTime.ToString();
}
}

public void ClosePlayer()
{
PlayCommand = "Close MediaFile";
mciSendString(PlayCommand, null, 0, IntPtr.Zero);
isOpen = false;
}


public void OpenMediaFile(string strFileName)
{
PlayCommand = "Open \"" + strFileName + "\" alias MediaFile";
mciSendString(PlayCommand, null, 0, IntPtr.Zero);
isOpen = true;
}


public void PlayMediaFile(bool loop)
{
if (isOpen)
{
PlayCommand = "Play MediaFile";
if (loop)
PlayCommand += " REPEAT";
mciSendString(PlayCommand, null, 0, IntPtr.Zero);
}
}

private void btnclose_Click(object sender, EventArgs e)
{
ClosePlayer();
}

private void btnplaysong_Click(object sender, EventArgs e)
{
PlayMediaFile(isOpen);
}

4) run the application.
