green arrow pointer

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.

Step 2: Apply Your License Key

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>
XML

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"
}

Step 3: Test your key

Test if your key has been installed correctly.

// Verify if the provided license key is valid
bool result = IronBarCode.License.IsValidLicense("IRONBARCODE-MYLICENSE-KEY-1EF01");

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

// Check if IronBarCode is licensed successfully
bool is_licensed = IronBarCode.License.IsLicensed;
' Verify if the provided license key is valid
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
