Implementation Guide

Feature 1: Load Source VSTX File

Overview Loading a source VSTX file is crucial as it sets up the document for further operations like adding more files or saving it after modifications.

Step-by-Step Implementation

using System;
using GroupDocs.Merger;

string vstxFilePath = "YOUR_DOCUMENT_DIRECTORY"; // Path to your source VSTX file
// Create an instance of Merger with the source VSTX file
going (var merger = new Merger(vstxFilePath))
{
    // The source VSTX file is now loaded and ready for further operations like merging
}

Explanation: Here, we create a Merger object by passing in the path to your source Visio file. This initializes the document, making it ready for additional files or other transformations.

Feature 2: Add Another VSTX File to Merge

Overview After loading the initial VSTX file, you can add more documents to be merged using the same Merger instance.

Step-by-Step Implementation

using GroupDocs.Merger;

string additionalVstxFolder = "YOUR_DOCUMENT_DIRECTORY"; // Directory containing additional files
string txtFilePathToAdd = Path.Combine(additionalVstxFolder, "additional.vstx"); // Path to another VSTX file
// Assuming 'merger' is a Merger instance already initialized with a source document
merger.Join(txtFilePathToAdd);

Explanation: The Join method adds the specified VSTX file to the existing merger setup, preparing multiple documents for merging.

Feature 3: Merge and Save VSTX Files

Overview The final step is to merge all loaded files into a single document and save it in your desired location.

Step-by-Step Implementation

using System.IO;
using GroupDocs.Merger;

string outputDirectory = "YOUR_OUTPUT_DIRECTORY"; // Path for saving the merged file
string mergedFileName = Path.Combine(outputDirectory, "merged.vstx"); // Output file name and path
// Assuming 'merger' is ready with documents loaded and ready to merge
merger.Save(mergedFileName);

Explanation: The Save method combines all added VSTX files into one and writes the result to a specified path.

Practical Applications
