Implementation Guide

This section covers two main features: setting the license from a file and from a stream.

Feature 1: Set License from File

Overview: Configure GroupDocs.Conversion using a license file to unlock full functionality.

Step 1: Check for License Existence

Ensure your license file exists at the specified path before applying it.

using System;
using System.IO;
using GroupDocs.Conversion.Licensing;

if (File.Exists("YOUR_DOCUMENT_DIRECTORY\\License.lic"))
{
    // Proceed to set the license
}
else
{
    Console.WriteLine("We do not ship any license with this example. " +
                      "Visit the GroupDocs site to obtain either a temporary or permanent license. " +
                      "Learn more about licensing at https://purchase.groupdocs.com/faqs/licensing. " +
                      "Learn how to request a temporary license at https://purchase.groupdocs.com/temporary-license.");
}

Step 2: Set License

Create an instance of the License class and apply your license using its full path.

License license = new License();
license.SetLicense("YOUR_DOCUMENT_DIRECTORY\\License.lic");

Feature 2: Stream License Configuration

Overview: Set a GroupDocs.Conversion license using an embedded resource stream.

Step 1: Load Embedded Resource

Open the embedded license file as a stream from your assembly resources.

using System;
using System.IO;
using System.Reflection;
using GroupDocs.Conversion.Licensing;

Stream licenseStream = Assembly.GetExecutingAssembly().GetManifestResourceStream("YOUR_DOCUMENT_DIRECTORY.GroupDocs.License.lic");
if (licenseStream != null)
{
    // Proceed to set the license using the stream
}
else
{
    Console.WriteLine("The embedded license resource could not be found. Please ensure it is correctly added as a resource in your project.");
}

Step 2: Apply License from Stream

Use the License class to apply the license via the stream.

License license = new License();
license.SetLicense(licenseStream);
