Using Iron Barcode License Keys

Install via NuGet

Before we start, we need to install the latest version of the Barcode NuGet Package.

Install-Package BarCode

You can find more information about the NuGet package here.

Install via DLL

As an alternative, the IronBarcode.dll could also be downloaded and added to your project.

Set your license using code

Add this code somewhere in the startup of your application, before IronBarcode is used.

// Apply your IronBarcode license key
IronBarCode.License.LicenseKey = "IRONBARCODE-MYLICENSE-KEY-1EF01";

// Apply your IronBarcode license key
IronBarCode.License.LicenseKey = "IRONBARCODE-MYLICENSE-KEY-1EF01";

' Apply your IronBarcode license key
IronBarCode.License.LicenseKey = "IRONBARCODE-MYLICENSE-KEY-1EF01"

Set your license using Web.Config or App.Config

To apply a key globally to your application using Web.Config or App.Config, add the following key to your config file in appSettings.

<configuration>
  ...
  <appSettings>
    <add key="IronBarCode.LicenseKey" value="IRONBARCODE-MYLICENSE-KEY-1EF01"/>
  </appSettings>
  ...
</configuration>

<configuration>
  ...
  <appSettings>
    <add key="IronBarCode.LicenseKey" value="IRONBARCODE-MYLICENSE-KEY-1EF01"/>
  </appSettings>
  ...
</configuration>

There is a known licensing issue between IronBarCode versions 2023.4.1 - 2024.3.2 with the following frameworks:

• ASP.NET projects
• .NET Framework version >= 4.6.2

The key stored in a Web.config file is NOT being picked up and used by the product. Visit the Setting License Key in Web.config troubleshooting article to learn more.

Set your license key using a .NET Core appsettings.json file

To apply a key globally to your application in a .NET Core project:

• Add a JSON file to your project called appsettings.json in the root directory of your project.
• Add a IronBarCode.LicenseKey key to your JSON config file. The value should be your license key.
• Ensure that the file properties include Copy to Output Directory: Copy always.

File: appsettings.json

{
  "IronBarCode.LicenseKey": "IRONBARCODE-MYLICENSE-KEY-1EF01"
}
