这几天帮同事解决一个连接扫描仪的问题，查阅了一下WIA的资料，写了一个类，比较简单，共享出来，方便大家来写扫描的组件。

这个类需要windows的WIA组件支持，具体内容我都放到附加的代码中了。

 

using System;

using System.Collections.Generic;

using System.Text;

using WIA;

namespace Scaner

{

    public class Scanner

    {

        public ImageFile Scan()

        {

            DeviceManager manager = new DeviceManager();

            Device device = null;

            foreach (DeviceInfo info in manager.DeviceInfos)

            {

                if (info.Type != WiaDeviceType.ScannerDeviceType) continue;

                device = info.Connect();

                break;

            }

            Item item = device.Items[1];

            CommonDialog cdc = new WIA.CommonDialog();

            ImageFile imageFile = cdc.ShowTransfer(item,

                "{B96B3CAB-0728-11D3-9D7B-0000F81EF32E}",

                true) as ImageFile;

            return imageFile;

        }

    }

}
