Need Assistance in Generating GS1 Datamatrix Code with GS (Group Separator Char(29))

akaraahmetoglu · July 2023

Hello everyone,

I am currently facing a challenge and kindly need your assistance. I'm trying to generate a GS1 Datamatrix code and in this process, I use &1; FNC1. However, I am having difficulties figuring out how to generate the required <GS> (Group Separator Char(29)).

Could anyone please shed some light on how I could possibly achieve this? Your input will be greatly appreciated.

Thank you for your time and help

Hello!

To resolve your issue, do not pass the raw character ((char)29).ToString() directly into the barcode text. When exporting via SVG/vector graphics, the character 0x1D is an invalid XML character and causes an XmlException (hexadecimal value 0x1D is an invalid character).

Example:

var dm = new BarcodeObject
{
Barcode = new BarcodeDatamatrix(),
Text = ‘&1;010460123456789021ABCDEF&1;91TEST&1;92SIGNATURE’
};
