但微软Windows图像采集（WIA）无法在Windows 10 64位系统上运行。



代码部分

I have use Microsoft Windows Image Acquisition (WIA) dll in .Net windows application to Scan document (.tiff images)

And It working fine with windows 7.

But Microsoft Windows Image acquisition (WIA) dll not wokring on Windows 10 64 bit system.

code part

img = (WIA.ImageFile)_scanner.Items[1].Transfer(WIA.FormatID.wiaFormatTIFF)

抛出异常

系统。 Runtime.InteropServices.COMException



附加信息：HRESULT异常：0x8021006B



请提供任何解决方案< br $>






代码： -

throws below exception
System. Runtime.InteropServices.COMException

   }

   WIA.ImageFile img;

   sFileName = FileName + DateAndTime.Now.ToString("_dd_MMM_yyyy_HH_mm_ss") + ".TIFF";
   sFullFileName = FolderPath + "\\" + sFileName;
   if (File.Exists(sFullFileName))
   {
      File.Delete(sFullFileName);
   }

   img.SaveFile(sFullFileName);

   img = null;
}
catch (Exception ex)
{
   throw ex;
}

我的尝试：



我已经从Windows 10 64位机器添加了WIA dll引用，但仍然得到相同的错误。

What I have tried:

I have added WIA dll references from windows 10 64 bit machine but still get same error.

推荐答案

第一个解决方案：



右键点击你的项目 - >点击属性 - >点击Build - >将平台目标更改为x86。



第二解决方案：

确保WIA.dll正在64位工作。

1st Solution:

Right click on your project-> Click on properties -> Click on Build -> Change Platform target to x86.

2nd Solution:
make sure WIA.dll is working on 64 bit.
