CD-ROM ınızı Açıp Kapatma

BU örnekte cd-rom u açıp kapatmayı göreceğiz. İlk önce formunuza Class ekleyin. Class a aşağıdaki kodları yazın. Class kısmına
using System.Runtime.InteropServices; eklemeyi unutmayın.

Class a yazılacak kodlar

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Runtime.InteropServices; 

namespace WindowsFormsApplication1
{
    class Class1
    {
      
        [DllImport("winmm.dll", EntryPoint = "mciSendStringA")]
        public static extern int mciSendString(string lpstrCommand,
               string lpstrReturnString, int uReturnLength, int hwndCallback);

        [DllImport("kernel32.dll", EntryPoint = "GetVolumeInformationA")]
        public static extern int GetVolumeInformation(string lpRootPathName,
               StringBuilder lpVolumeNameBuffer, int nVolumeNameSize,
               int lpVolumeSerialNumber, int lpMaximumComponentLength,
               int lpFileSystemFlags, string lpFileSystemNameBuffer,
               int nFileSystemNameSize);

      
        [DllImport("kernel32.dll", EntryPoint = "GetDriveTypeA")]
        public static extern int GetDriveType(string nDrive);
    }
}

Forma yazacağınız kodlar

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        int i;
        public Form1()
        {
            InitializeComponent();
        }

        private void button1_Click(object sender, EventArgs e)
        {

            if (i == Class1.mciSendString("set CDAudio door closed", null, 127, 0))
            {
                Class1.mciSendString("set CDAudio door open", null, 127, 0);
                //MessageBox.Show("CD-ROM şu an açık");
                button1.Text = "CD-ROM şu an açık "; 
            }
                else if (i == Class1.mciSendString("set CDAudio door open", null, 127, 0))
               
                {
                    Class1.mciSendString("set CDAudio door closed", null, 127, 0);
                    //MessageBox.Show("CD-ROM şu an açık");
                    button1.Text = "CD-ROM şu an kapalı ";
            }
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            button1.Text = "CD-ROM Aç/Kapa";
        }
    }     
 }
