Implementation Guide

Setting License From File

This feature ensures your application is authorized by applying a valid license. Follow these steps to implement it:

Step 1: Verify License File Existence

Before setting the license, check if the file exists in your specified directory.

Check and Set License Code:

using System;
using System.IO;
using GroupDocs.Comparison;

public class LicenseSetup {
    public static void ApplyLicense(string documentDirectory) {
        // Check if the specified license path exists
        string licensePath = Path.Combine(documentDirectory, "License.lic");
        
        if (File.Exists(licensePath)) {
            // Create a new License object
            License license = new License();
            
            // Set the license from file
            license.SetLicense(licensePath);
            Console.WriteLine("License applied successfully.");
        } else {
            Console.WriteLine("License file not found.");
        }
    }
}

Explanation:

  • File.Exists: Checks if the specified license file exists at the given path.
  • SetLicense Method: Applies the license to your application, ensuring it runs without evaluation limitations.
