An output from a good API must be versatile enough for users to use it further in their program or application, and not necessarily be saved on the disk. That is why IronBarcode offers many options for users to export the GeneratedBarcode into various types, and one of them is exporting the barcodes generated as HTML.

Speaking of exporting the GeneratedBarcode into HTML as either a Data URL, HTML Tag, or HTML File, in this article, we'll discuss how we can export to each format.

How to Export Barcodes as HTML in C#

Export Barcode as Data URL

Before discussing how to export a barcode as a Data URL, we need to first know what exactly is a data URL. Data URL, also known as Data URI, is a type of Uniform Resource Identifier (URI) that allows data to be embedded directly in the URL string, inline in web pages as if they were external resources. This can be in any format, which includes text, images, audio, video, and binary data. The obtained Data URL can later be used in HTML inside an image tag as a src attribute. Here's a code snippet demonstrating how we can convert our GeneratedBarcode into a Data URL.

:path=/static-assets/barcode/content-code-examples/how-to/ExportBarcodeAsDataUrl.cs
using IronBarCode;
using System;

GeneratedBarcode myBarcode = BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode/", BarcodeEncoding.QRCode);
var dataUrl = myBarcode.ToDataUrl();
Console.WriteLine(dataUrl);
Imports IronBarCode
Imports System

Private myBarcode As GeneratedBarcode = BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode/", BarcodeEncoding.QRCode)
Private dataUrl = myBarcode.ToDataUrl()
Console.WriteLine(dataUrl)
$vbLabelText   $csharpLabel

From the code snippet above, we started off with creating a barcode using the CreateBarcode() method from the BarcodeWriter class with the barcode value and the barcode encoding as the arguments for this method. In order to get the Data URL of the barcode, we attached the ToDataUrl() method to the GeneratedBarcode.

Export Barcode as HTML Tag

Another way to export our GeneratedBarcode to HTML is by exporting it into an HTML tag using the ToHtmlTag() method. This method renders the GeneratedBarcode object as a fully formed HTML tag that can be injected directly into HTML without having to reference it in any JavaScript, CSS, or image dependencies. The following code snippet demonstrates how to export as an HTML tag.

:path=/static-assets/barcode/content-code-examples/how-to/ExportBarcodeAsHtmlTag.cs
using IronBarCode;
using System;

GeneratedBarcode myBarcode = BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode/", BarcodeEncoding.QRCode);
var htmlTag = myBarcode.ToHtmlTag();
Console.WriteLine(htmlTag);
Imports IronBarCode
Imports System

Private myBarcode As GeneratedBarcode = BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode/", BarcodeEncoding.QRCode)
Private htmlTag = myBarcode.ToHtmlTag()
Console.WriteLine(htmlTag)
$vbLabelText   $csharpLabel

From the code snippet above, we can simply attach the ToHtmlTag() method to the GeneratedBarcode in order to obtain the HTML tag of the barcode generated. This HTML tag can directly be embedded into a larger HTML file.

Export Barcode as HTML File

Users can also opt to save the GeneratedBarcode as an HTML file instead. To do this, use the SaveAsHtmlFile() method. The following code snippet demonstrates how to use this method.

:path=/static-assets/barcode/content-code-examples/how-to/ExportBarcodeAsHtmlFile.cs
using IronBarCode;

GeneratedBarcode myBarcode = BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode/", BarcodeEncoding.QRCode);
myBarcode.SaveAsHtmlFile("myBarcode.html");
Imports IronBarCode

Private myBarcode As GeneratedBarcode = BarcodeWriter.CreateBarcode("https://ironsoftware.com/csharp/barcode/", BarcodeEncoding.QRCode)
myBarcode.SaveAsHtmlFile("myBarcode.html")
$vbLabelText   $csharpLabel

This method accepts a string of a file path. Looking into the HTML file generated, we can see the barcode outputted as an HTML tag within the <html>, <head>, and <body> tags that make up a complete HTML file.
