Scan barcode from Images is fairly simple with Free Spire.Barcode library, you can get it from NuGet and then use this line of code to read barcode data:
string[] data = Spire.Barcode.BarcodeScanner.Scan("QRCode.png", Spire.Barcode.BarCodeType.QRCode);
Check the tutorial here for more information:

If you have images that contain barcodes, you can add barcode scanning using the LEADTOOLS toolkit (https://www.leadtools.com/sdk/barcode). The Barcode SDK can detect, read, and write 1D and 2D barcodes in images. It is also integrated with the library's HTML5/JavaScript Document library which you can use in your ASP.NET project.
The code to recognize barcodes in a document looks like this:
function barcodesExample() {
// Load a new document
var url = "https://demo.leadtools.com/images/tiff/barcode.tif";
console.log("Loading document ...");
var loadDocumentOptions = new lt.Documents.LoadDocumentOptions();
lt.Documents.DocumentFactory.loadFromUri(url, loadDocumentOptions)
   .done(function (doc) {
    console.log("Done. Reading barcodes ...");
    // Read all the barcodes in the first page
    var docPage = doc.pages.item(0);
    docPage.readBarcodes(lt.LeadRectD.empty, 0, null)
      .done(function (barcodes) {
       console.log("Number of barcodes read " + barcodes.length);
       for (var i = 0; i < barcodes.length; i++) {
        var barcodeData = barcodes[i];
        console.log("  Symbology:" + barcodeData.symbology);
        console.log("  Bounds:" + barcodeData.bounds.x + "," + barcodeData.bounds.y + "," + barcodeData.bounds.width + "," + barcodeData.bounds.height);
        console.log("  Value:" + barcodeData.value);
       }
      })
      .fail(function (jqXHR, statusText, errorThrown) {
       showServiceError(jqXHR, statusText, errorThrown);
      });
   })
   .fail(function (jqXHR, statusText, errorThrown) {
    showServiceError(jqXHR, statusText, errorThrown);
   });
}
