using GroupDocs.Merger;

class Program
{
    static void Main(string[] args)
    {
        string filePath = @"YOUR_DOCUMENT_DIRECTORY/sample.docm";
        
        using (var merger = new Merger(filePath))
        {
            Console.WriteLine("File loaded successfully.");
            // Ready for further operations like merging or splitting.
        }
    }
}

Implementation Guide

Now, let’s explore the core functionalities: loading a DOCM file and merging multiple DOCM files.

Load a DOCM File

This feature demonstrates how to load a Microsoft Word Macro-Enabled Document (.docm) using GroupDocs.Merger.

Overview

Loading documents is the first step in any manipulation process. It sets the stage for subsequent operations like merging or splitting.

Implementation Steps

  1. Set Up the File Path: Define the path to your DOCM file.
  2. Initialize Merger Object: Create an instance of the Merger class with your file path.
using System;
using GroupDocs.Merger;

class Program
{
    static void Main(string[] args)
    {
        string filePath = Path.Combine(@"YOUR_DOCUMENT_DIRECTORY", "sample.docm");

        // Load the DOCM file using GroupDocs.Merger
        using (var merger = new Merger(filePath))
        {
            Console.WriteLine("File loaded successfully.");
        }
    }
}

Merge Multiple DOCM Files into a Single File

Combining several documents into one can streamline workflows and simplify document management.

Overview

This feature enables you to merge two or more DOCM files into a single file, preserving the integrity of each source document.

Implementation Steps

  1. Define Source Files: Specify the paths for the DOCM files you want to merge.
  2. Initialize Merger Object with First File: Start by loading the first document.
  3. Add Additional Files: Use the Join method to add more documents to be merged.
  4. Save Merged Document: Output the combined file to a specified location.
using System;
using GroupDocs.Merger;
using System.IO;

class Program
{
    static void Main(string[] args)
    {
        string sourceFilePath1 = Path.Combine(@"YOUR_DOCUMENT_DIRECTORY", "sample.docm");
        string sourceFilePath2 = Path.Combine(@"YOUR_DOCUMENT_DIRECTORY", "sample2.docm");

        // Define the output directory and file path
        string outputFolder = @"YOUR_OUTPUT_DIRECTORY";
        string outputFile = Path.Combine(outputFolder, "merged.docm");

        // Load the first DOCM source file
        using (var merger = new Merger(sourceFilePath1))
        {
            // Add another DOCM file to merge
            merger.Join(sourceFilePath2);

            // Save the merged document to the specified output path
            merger.Save(outputFile);
            
            Console.WriteLine("Documents merged successfully.");
        }
    }
}

Troubleshooting Tips

  • Ensure File Paths are Correct: Double-check your directory paths to avoid file not found errors.
  • Check File Permissions: Make sure your application has the necessary permissions to read and write files in specified directories.

Practical Applications

GroupDocs.Merger for .NET is versatile, offering a range of applications:
