Implementation Guide: Setting License from File

In this section, we’ll walk through setting a license for GroupDocs.Editor using a file path in .NET.

Overview of Feature

This feature allows you to apply a license by specifying the path to your license file. This is crucial for unlocking all functionalities provided by the library.

Step 1: Define License Path

Start by specifying the location of your license file relative to your executable or GroupDocs.Editor.dll.

const string LicensePath = "YOUR_DOCUMENT_DIRECTORY\\GroupDocs.Editor.lic";

Why: This path is essential for locating the correct file during runtime.

Step 2: Check File Existence

Verify that the license file exists at the specified location to prevent runtime errors.

if (File.Exists(LicensePath))
{
    // Proceed with setting the license
}
else
{
    Console.WriteLine("License file not found.");
}

Why: Ensures your application doesn’t attempt to set a non-existent license, which could lead to unexpected behavior.

Step 3: Apply License

Once confirmed, use the SetLicense method from GroupDocs.Editor’s licensing namespace to apply it.

using System.IO;
using GroupDocs.Editor.Licensing;

public static void RunSetLicenseFromFile()
{
    if (File.Exists(LicensePath))
    {
        License license = new License();
        
        // Set the license using the specified file path
        license.SetLicense(LicensePath);
        
        Console.WriteLine("License set successfully.");
    }
}

Why: Applying the license is crucial for accessing all functionalities offered by GroupDocs.Editor without limitations.

Troubleshooting Tips

  • File Path Errors: Double-check the directory and filename.
  • Permissions Issues: Ensure your application has read access to the license file.
  • Invalid License File: Confirm that you’re using a valid, non-expired license file.
