        License license = new License();
        license.SetLicense("Path to your license file");

        Console.WriteLine("GroupDocs.Comparison for .NET is ready to use.");
    }
}

Implementation Guide

Let’s implement folder comparison and save results as TXT or HTML files using GroupDocs.Comparison.

Compare Folders and Save Results as TXT

Overview

This feature allows you to compare two folders and output the differences in a text file, making it easy to review changes line by line.

Step 1: Configure Comparison Options

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

string sourceFolder = "YOUR_DOCUMENT_DIRECTORY/SOURCE_FOLDER";
string targetFolder = "YOUR_DOCUMENT_DIRECTORY/TARGET_FOLDER";
string outputDirectory = "YOUR_OUTPUT_DIRECTORY";

// Set comparison options for TXT output
Options.CompareOptions compareOptionsTxt = new Options.CompareOptions
{
    DirectoryCompare = true,
    FolderComparisonExtension = GroupDocs.Comparison.Options.FolderComparisonExtension.Txt
};

Step 2: Initialize Comparer Object

Comparer comparerTxt = new Comparer(sourceFolder, compareOptionsTxt);
// Add target folder for comparison
comparerTxt.Add(targetFolder, compareOptionsTxt);

Step 3: Perform Comparison and Save Result

string txtOutputFileName = Path.Combine(outputDirectory, "ComparisonResult.txt");
comparerTxt.Compare(txtOutputFileName, compareOptionsTxt);

Console.WriteLine("TXT file with comparison results saved successfully.");

Compare Folders and Save Results as HTML

Overview

This feature helps you visualize differences by generating an HTML report that highlights changes.

Step 1: Configure Comparison Options for HTML Output

// Set comparison options for HTML output
Options.CompareOptions compareOptionsHtml = new Options.CompareOptions
{
    DirectoryCompare = true,
    FolderComparisonExtension = GroupDocs.Comparison.Options.FolderComparisonExtension.Html
};

Step 2: Initialize Comparer Object for HTML

Comparer comparerHtml = new Comparer(sourceFolder, compareOptionsHtml);
// Add target folder to the comparison
comparerHtml.Add(targetFolder, compareOptionsHtml);

Step 3: Perform Comparison and Save Result as HTML

string htmlOutputFileName = Path.Combine(outputDirectory, "ComparisonResult.html");
comparerHtml.Compare(htmlOutputFileName, compareOptionsHtml);

Console.WriteLine("HTML file with comparison results saved successfully.");

Troubleshooting Tips

  • Ensure directory paths are correctly specified.
  • Check for write permissions in the output directory.
  • Verify that all necessary files and dependencies are present.

Practical Applications

Here are some real-world use cases where folder comparison can be beneficial:

  1. Code Review: Compare different versions of a codebase to identify changes.
  2. Data Backup Verification: Ensure backups match original data folders.
  3. Configuration Management: Track changes in configuration files across environments.
  4. Document Versioning: Maintain consistency in document updates and revisions.
  5. Integration with CI/CD Pipelines: Automate comparison checks as part of deployment processes.

Performance Considerations

To ensure optimal performance when using GroupDocs.Comparison:

  • Minimize the number of files within each folder to reduce processing time, if possible.
  • Use efficient data structures for file storage and access.
  • Monitor memory usage and manage resources effectively in .NET applications.

Conclusion

Congratulations! You’ve learned how to implement folder comparison with GroupDocs.Comparison for .NET, saving results as TXT or HTML. These skills will enhance your ability to manage and compare large datasets efficiently.

As next steps, consider exploring more advanced features of GroupDocs.Comparison, such as comparing specific file types or integrating the tool into larger applications.
