Step 1:
Download barcode reader dll from here and add the reference to Onbarcode.Barcode.BarcodeScanner to your application.
Step 2:
This BarcodeScanner dll contain so many methods to scan the barcode image and retrive the data present in those images. Write this two methods to scan the barcode images.
1) ReadBarcodeFromFile:
This method is very simple method to scan the barcode image which will take the filenpath as argument where barcode image is present and retrive String[] as data.
private String[] ReadBarcodeFromFile(string _Filepath)
{
String[] barcodes = BarcodeScanner.Scan(_Filepath, BarcodeType.Code39);
return barcodes;
}
2) Read BarcodeFromBitmap:
This one other method is provided by BarcodeScanner dll which will take Bitmap image as input and returns same String[] as output.
private String[] ReadBarcodeFromBitmap(Bitmap _bimapimage)
{
System.Drawing.Bitmap objImage = _bimapimage;
String[] barcodes = BarcodeScanner.Scan(objImage, BarcodeType.Code39);
return barcodes;
}
You can call this method by passing barcode image as bitmap.
Conclusion:
In this way we can scan the barcode images using C#.
