Hi,
You have to use winmm.dll API
//Import winmm.dll        
[DllImport("winmm.dll")]        
static extern Int32 mciSendString(String command, StringBuilder buffer, Int32 bufferSize, IntPtr hwndCallback);        
private void Close()        
{            
//Closes the Cd Tray            
mciSendString("set CDAudio door closed", null, 0, IntPtr.Zero);        
}        
private void open()        
{            
//Opens the Cd Tray of your cd Drive            
mciSendString("set CDAudio door open", null, 0, IntPtr.Zero);        
}

//private field:
private long setTrayStatus;
      //API


//use this code to open the tray:

 // ERROR: Not supported in C#: DeclareDeclaration
 setTrayStatus = mciSendString("Set CDAudio Door Open", null, 0, 0);
//use this code to close the tray:
 setTrayStatus = mciSendString("Set CDAudio Door Closed", null, 0, 0);

Hi, use the following code.


using System.Runtime.InteropServices;
[DllImport("winmm.dll")]
static extern Int32 mciSendString(String command, StringBuilder buffer, Int32 bufferSize, IntPtr hwndCallback);

mciSendString("set CDAudio door open", null, 0, IntPtr.Zero);
mciSendString("set CDAudio door closed", null, 0, IntPtr.Zero);

// Open Drive H:
mciSendString("open H: type CDAudio alias driveH", null, 0, IntPtr.Zero);
mciSendString("set driveH door open", null, 0, IntPtr.Zero);
// Open Drive I:
mciSendString("open I: type CDAudio alias driveI", null, 0, IntPtr.Zero);
mciSendString("set driveI door open", null, 0, IntPtr.Zero);

// Close Drive H:
mciSendString("open H: type CDAudio alias driveH", null, 0, IntPtr.Zero);
mciSendString("set driveH door closed", null, 0, IntPtr.Zero);
// Close Drive I:
mciSendString("open I: type CDAudio alias driveI", null, 0, IntPtr.Zero);
mciSendString("set driveI door closed", null, 0, IntPtr.Zero);
