Integrate image scanning within a C# application

Now, include the WIA library (C:\Windows\System32\wiaaut.dll) within your project by adding a reference to it :

 

Figure 2.

Add a new class to your project and name it Scanner:

using System;
using WIA;

namespace ScanImage
{
public class Scanner
{
Device oDevice;
Item oItem;
CommonDialogClass dlg;
public Scanner()
{
dlg = new CommonDialogClass();
oDevice = dlg.ShowSelectDevice(WiaDeviceType.ScannerDeviceType, true, false);
}
public void Scann()
{
dlg.ShowAcquisitionWizard(oDevice);
}
}
}

In order to consume the services of this very simple class add a button and a picture box to your form as your project is Windows form one, the form should looks like this bellow:

 

Figure 3.

Do implement the button1_click as follow:

private void button1_Click(object sender, EventArgs e)
{
   Scanner oScanner = new Scanner();
oScanner.Scann();
button1.Text = “Image scanned”;
  OpenFileDialog dlg = new OpenFileDialog();
if (dlg.ShowDialog() == DialogResult.OK)
{
pictureBox1.Image = Image.FromFile(dlg.FileName);
}
}

Now run the application and observe:
