Setting Up GroupDocs.Conversion for .NET

Installation Instructions

To integrate GroupDocs.Conversion into your project, you can install it via NuGet or .NET CLI:

NuGet Package Manager Console

Install-Package GroupDocs.Conversion -Version 25.3.0

.NET CLI

dotnet add package GroupDocs.Conversion --version 25.3.0

Basic Initialization and Setup

Once installed, initialize the library in your C# application:

using System;
using System.IO;
using GroupDocs.Conversion;
using GroupDocs.Conversion.Options.Convert;

// Initialize converter with input DOCX file path
string inputFilePath = @"YOUR_DOCUMENT_DIRECTORY\\sample.docx";

Implementation Guide

This section breaks down the conversion process into manageable steps.

Feature Overview: DOCX to PDF Conversion

Converting Word documents to PDFs maintains formatting and content integrity. This feature is useful for document preservation and sharing across platforms.

Step 1: Define File Paths

Specify the input and output file paths:

string outputFolder = @"YOUR_OUTPUT_DIRECTORY";
string outputFile = Path.Combine(outputFolder, "docx-converted-to.pdf");

Step 2: Load the Source DOCX File

Load your DOCX document using GroupDocs.Conversion’s Converter class:

using (var converter = new Converter(inputFilePath))
{
    // Conversion logic will go here
}

Here, we’re encapsulating file operations within a using statement to ensure resources are properly disposed of.

Step 3: Define PDF Conversion Options

Specify your conversion options tailored for the PDF format:

var options = new PdfConvertOptions();
// Additional configurations can be set here if needed

Step 4: Perform and Save Conversion

Execute the conversion process and save the output file:

converter.Convert(outputFile, options);

This method call transforms your DOCX into a PDF using the defined options.

Troubleshooting Tips

  • File Not Found: Ensure paths are correct and files exist.
  • Permission Issues: Verify read/write permissions for directories involved.
  • Library Version Conflicts: Check compatibility with .NET Framework versions used.
