How to generate a UPC-A barcode as a PNG file in C# .NET Framework

Today we are going to take the pain and suffering out of creating UPC-A barcodes. I suppose it’s not all that bad, but why do all that work if you don’t have to? We have a handy dandy API that can generate that barcode for you, and the whole process takes almost no time at all.

First, install the barcode API with this Package Manager command:

Install-Package Cloudmersive.APIClient.NET.Barcode -Version 2.0.2

From there, call the function for UPC-A codes, like so:

using System;
using System.Diagnostics;
using Cloudmersive.APIClient.NET.Barcode.Api;
using Cloudmersive.APIClient.NET.Barcode.Client;
using Cloudmersive.APIClient.NET.Barcode.Model;
namespace Example
{
public class GenerateBarcodeUPCAExample
{
public void main()
{
// Configure API key authorization: Apikey
Configuration.Default.AddApiKey("Apikey", "YOUR_API_KEY");
// Uncomment below to setup prefix (e.g. Bearer) for API key, if needed
// Configuration.Default.AddApiKeyPrefix("Apikey", "Bearer");
var apiInstance = new GenerateBarcodeApi();
var value = value_example;  // string | UPC-A barcode value to generate from
try
{
// Validate and generate a UPC-A barcode as a PNG file, a type of 1D barcode
System.IO.Stream result = apiInstance.GenerateBarcodeUPCA(value);
Debug.WriteLine(result);
}
catch (Exception e)
{
Debug.Print("Exception when calling GenerateBarcodeApi.GenerateBarcodeUPCA: " + e.Message );
}
}
}
}

All done! Any string entered in will be converted into a PNG of the barcode and sent back. Seriously, why would you do this any other way?
