class Program
{
    static void Main()
    {
        Document doc1 = new Document("Document1.docx");
        Document doc2 = new Document("Document2.docx");

        Console.WriteLine("Documents loaded successfully.");
    }
}

Explanation: This code loads two Word documents, preparing them for the comparison process.

Step 2: Comparing the Documents and Highlighting Differences

Compare the documents and highlight the differences using Aspose.Words’ built-in comparison functionality.

using System;
using Aspose.Words;

class Program
{
    static void Main()
    {
        Document doc1 = new Document("Document1.docx");
        Document doc2 = new Document("Document2.docx");

        doc1.Compare(doc2, "Reviewer", DateTime.Now);

        Console.WriteLine("Documents compared successfully.");
    }
}

Explanation: This code compares the two documents and marks the differences, simulating a reviewer’s changes.

Step 3: Saving the Comparison Report

Save the comparison results to a new Word document, creating a detailed report of the differences.

using System;
using Aspose.Words;

class Program
{
    static void Main()
    {
        Document doc1 = new Document("Document1.docx");
        Document doc2 = new Document("Document2.docx");

        doc1.Compare(doc2, "Reviewer", DateTime.Now);

        string outputPath = "ComparisonReport.docx";
        doc1.Save(outputPath);

        Console.WriteLine($"Comparison report saved to {outputPath}");
