错误信息:
无法加载文件或程序集“Interop.WIA,Version=1.0.0.0,Culture=neutral,PublicKeyToken=null”或其依赖项之一。试图加载格式不正确的程序。
该解决方案在使用普通 USB 扫描仪的 Windows XP 上运行良好,但是在上面的 Windows 7 (x64) 上尝试使用网络扫描仪(使用 Scangear 工具发现)进行扫描时遇到了问题。
C#代码:
private void startscan()
{
try
{
CommonDialogClass dailog = new CommonDialogClass();
ImageFile imgfile = (ImageFile)dailog.ShowAcquireImage(WiaDeviceType.ScannerDeviceType, WiaImageIntent.UnspecifiedIntent, WiaImageBias.MaximizeQuality,
FormatID.wiaFormatJPEG, true, true, false);
string firstname = DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString();
string name = scantxtfname.Text.Trim() + ".jpeg";
string filenamepath = ConfigurationManager.ConnectionStrings["scanfilepath"].ConnectionString.ToString() + firstname + name;
scanfile.Add(name);
firstint.Add(Convert.ToInt32(firstname));
SaveImageToPNGFile(imgfile, filenamepath);
FileStream stream = new FileStream(filenamepath, FileMode.Open, FileAccess.Read);
stream.Close();
DataTable dt = new DataTable();
dt.Columns.Add("Scaned Files", typeof(string));
datagridscanedfiles.DataSource = null;
for (int i = 0; i < scanfile.Count; i++)
{
DataRow r = dt.NewRow();
r[0] = scanfile[i].ToString();
dt.Rows.Add(r);
}
datagridscanedfiles.DataSource = dt;
datagridscanedfiles.Visible = true;
int ln = scanfile.Count;
pictureBox1.ImageLocation = filenamepath;
}
catch ( Exception d)
{
MessageBox.Show(d.Message);
}
}
private static void SaveImageToPNGFile(ImageFile image, string fileName)
{
try
{
ImageProcess imgProcess = new ImageProcess();
object convertFilter = "Convert";
string convertFilterID = imgProcess.FilterInfos.get_Item(ref convertFilter).FilterID;
imgProcess.Filters.Add(convertFilterID, 0);
SetWIAProperty(imgProcess.Filters[imgProcess.Filters.Count].Properties, "FormatID", WIA.FormatID.wiaFormatJPEG);
image = imgProcess.Apply(image);
image.SaveFile(fileName);
}
catch (Exception er)
{
MessageBox.Show(er.Message);
}
}
private static void SetWIAProperty(IProperties properties, object propName, object propValue)
{
Property prop = properties.get_Item(ref propName);
prop.set_Value(ref propValue);
}
请建议我如何解决上述问题?
