How can Barcodelib be used to generate a GS1-128 barcode in C#?

edit

To generate a GS1-128 barcode in C# using Barcodelib, follow these steps:

1. Install the Barcodelib library from NuGet:

Install-Package Barcodelib

1. Import the Barcodelib namespace:

using BarcodeLib;

1. Create a new instance of the Barcode class:

Barcode barcode = new Barcode();

1. Set the BarcodeType property to "GS1-128":

barcode.BarcodeType = BarcodeType.GS1_128;

1. Set the data to be encoded in the barcode using the Encode method:

string data = "(01)01234567891234(17)180801(21)190123(10)ABC123";
Image barcodeImage = barcode.Encode(BarcodeLib.TYPE.CODE128, data);

In this example, the data is a GS1-128 formatted string. The "(01)" indicates the Global Trade Item Number (GTIN), the "(17)" indicates the expiration date, the "(21)" indicates the serial number, and the "(10)" indicates the batch/lot number.

1. The barcode is generated as an Image object. You can then save the image to a file or display it in a picture box:

barcodeImage.Save("barcode.png", ImageFormat.Png);
