Step 2: Apply Your License Key

Set your IronOCR license key using code

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

IronOcr.License.LicenseKey = "IRONOCR-MYLICENSE-KEY-1EF01";
IronOcr.License.LicenseKey = "IRONOCR-MYLICENSE-KEY-1EF01";
IronOcr.License.LicenseKey = "IRONOCR-MYLICENSE-KEY-1EF01"

You can validate that your software is licensed using either IronOcr.License.IsValidLicense(string LicenseKey) or the IronOcr.License.IsLicensed property.

Set your license key 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="IronOcr.LicenseKey" value="IRONOCR-MYLICENSE-KEY-1EF01"/>
   </appSettings>
   ....
</configuration>
XML

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

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

  • Add a JSON file to your project called appsettings.json in the root directory of your project
  • Add a 'IronOcr.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
  • Ensure that IronOcr.License.IsLicensed returns true to verify.

File: appsettings.json

{

    "IronOcr.LicenseKey":"IRONOCR-MYLICENSE-KEY-1EF01"

}

Step 3: Test your key

Test if your key has been installed correctly.

bool result = IronOcr.License.IsValidLicense("IRONOCR-MYLICENSE-KEY-1EF01");
bool result = IronOcr.License.IsValidLicense("IRONOCR-MYLICENSE-KEY-1EF01");
Dim result As Boolean = IronOcr.License.IsValidLicense("IRONOCR-MYLICENSE-KEY-1EF01")
