Install via NuGet

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

Install-Package BarCode

https://www.nuget.org/packages/BarCode/

Install via DLL

As an alternative, the IronBarCode.Dll can be downloaded and added to your project as a reference from [.NET Barcode DLL].

Step 2: Apply Your License Key

Set your license using code

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

IronBarCode.License.LicenseKey = "IRONBARCODE-MYLICENSE-KEY-1EF01";
IronBarCode.License.LicenseKey = "IRONBARCODE-MYLICENSE-KEY-1EF01";
IronBarCode.License.LicenseKey = "IRONBARCODE-MYLICENSE-KEY-1EF01"
VB   C#

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>
XML

There is a known licensing issue between IronBarCode version 2023.4.1 - 2024.3.2 on project:

  • 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.

Ensure that IronBarCode.License.IsLicensed returns true to verify.

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

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

  • 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"
}

Step 3: Test your key

Test if your key has been installed correctly.

bool result = IronBarCode.License.IsValidLicense("IRONBARCODE-MYLICENSE-KEY-1EF01");

// Check if IronBarCode is licensed successfully 
bool is_licensed = IronBarCode.License.IsLicensed;
bool result = IronBarCode.License.IsValidLicense("IRONBARCODE-MYLICENSE-KEY-1EF01");

// Check if IronBarCode is licensed successfully 
bool is_licensed = IronBarCode.License.IsLicensed;
Dim result As Boolean = IronBarCode.License.IsValidLicense("IRONBARCODE-MYLICENSE-KEY-1EF01")

' Check if IronBarCode is licensed successfully 
Dim is_licensed As Boolean = IronBarCode.License.IsLicensed
VB   C#
