扫描图像并将其保存在特定文件夹中

Question

我创建了Windows窗体应用程序来扫描任何图像。

扫描完成后，它会要求用户将其保存在任何文件夹中，但我希望将图像保存在特定的文件夹中。

我用的代码：

public class Scanner 
{ 
    Device oDevice; 
    Item oItem; 
    CommonDialogClass dlg; 

    public Scanner() 
    { 
     dlg = new CommonDialogClass(); 
     oDevice = dlg.ShowSelectDevice(WiaDeviceType.ScannerDeviceType, true, false); 
    } 

    public void Scann() 
    { 
     try 
     { 
      dlg.ShowAcquisitionWizard(oDevice); 
     } 
     catch (NullReferenceException ex) 
     { 
      MessageBox.Show(ex.Message); 
     } 

    } 
} 

private void button1_Click(object sender, EventArgs e) 
{ 
    Scanner oScanner = new Scanner(); 
    oScanner.Scann(); 

    //Saving the image to the server directly 
    button1.Text = "Image scanned"; 

    OpenFileDialog dlg = new OpenFileDialog(); 

    if (dlg.ShowDialog() == DialogResult.OK) 
    { 
     pictureBox1.Image = Image.FromFile(dlg.FileName); 
    }    
} 

Answer 1

使用CommonDialog.ShowTransfer method。

实施例：

Device scanner = dialog.ShowSelectDevice(WiaDeviceType.ScannerDeviceType, true, false); 
Item scannnerItem = scanner.Items[1]; 
// TODO: Adjust scanner settings. 

ImageFile scannedImage = (ImageFile)dialog.ShowTransfer(scannnerItem, WIA.FormatID.wiaFormatPNG, false); 
scannedImage.SaveFile("path");
