Hi Ivan,

You can generate barcode using below link,
https://www.codeproject.com/Articles/30322/Barcodes-in-ASP-NET-applications

You need to download IdAutomation font from this link
https://www.1001freefonts.com/idautomation.com-code-39-barcode-font-free-version.font

Note: One thing to note here is that need to install font first then need to restart system to make font reflect on borcode. Without restart it want work I personally faced this issue thats why I am puting this infront.

You can use LEADTOOLS Barcode SDK technology in your application.
https://www.leadtools.com/sdk/barcode
Here is some sample code:
using (RasterCodecs codecs = new RasterCodecs())
{
    using(RasterImage image = codecs.Load(@"FILE PATH TO BARCODE IMAGE"))
    {
        // Create a Barcode engine
        BarcodeEngine engine = new BarcodeEngine();

        // Get the Barcode reader instance
        BarcodeReader reader = engine.Reader;

        BarcodeData barcode = reader.ReadBarcode(image, LeadRect.Empty, BarcodeSymbology.Unknown, null);
        if (barcode != null)
        {
            Console.WriteLine($"Barcode Symbology: {data.Symbology}\nValue: {data.Value}\nBounds: {data.Bounds}");
        }
        else
        {
            Console.WriteLine("Not found");
        }
    }
}

Using free barcode API ( http://freebarcode.codeplex.com/) you can scan barcode as easy as following code

string scanResult = BarcodeScanner.ScanOne(picFile);

The simplest way is to use a barcode reader.

Refer to this article:

There are two components to a barcode: 1) the image of the barcode itself and 2) the data that can be extracted from the barcode. iOS 7+ supports finding a barcode in an image and also extracting the data from that image without external libraries. There are many strong tutorials and answers related to barcode recognition but you are probably looking for this one:http://www.infragistics.com/community/blogs/torrey-betts/archive/2013/10/10/scanning-barcodes-with-ios-7-objective-c.aspx
I can think of two ways to achieve what you wish, capturing a barcode then displaying it on-screen: 1) crop the larger image where the barcode was detected so that only the barcode is left, then display that, or 2) once a barcode is detected create a new barcode. The advantage of the first method is you can crop slightly larger so the barcode will clearly appear like the original but any imperfections (stains, shadows, etc...) will be left. The advantage of the second is you will have a crystal clear barcode but the user experience might appear a little disjointed (or it may look like magic: you'll have "cleaned up" a smudged barcode). Choosing one depends on the type of user experience you wish for.
