        var converter = new Converter("path/to/your/document.docx");
    }
}

Implementation Guide

Retrieving Possible Conversions

Overview

Discover the range of formats you can convert a document into using GroupDocs.Conversion.

Step-by-Step Implementation

Retrieve Conversion Options

using System;
using GroupDocs.Conversion.Contracts;

string inputFile = "YOUR_DOCUMENT_DIRECTORY/sample.docx";
var possibleConversions = Converter.GetPossibleConversions(inputFile);

foreach (var conversion in possibleConversions)
{
    Console.WriteLine(conversion.Format);
}

Explanation: This snippet retrieves all formats that a DOCX file can be converted to, using the GetPossibleConversions method which returns an array of conversion options.

Configuring Load Options for Word Documents

Overview

Learn how to handle password-protected documents securely.

Step-by-Step Implementation

Set Up Password Protection

using System;
using GroupDocs.Conversion.Options.Load;

string inputFile = "YOUR_DOCUMENT_DIRECTORY/sample.docx";
var loadOptions = (WordProcessingLoadOptions) Converter.GetPossibleConversions(inputFile).LoadOptions;
loadOptions.Password = "12345";

Console.WriteLine("Password set in load options: {0}", loadOptions.Password);

Explanation: Here, we configure WordProcessingLoadOptions to specify a password for protected documents. This ensures that only authorized users can access the content.

Converting Document to PDF Format

Overview

Convert Word documents into PDFs effortlessly with tailored conversion settings.

Step-by-Step Implementation

Convert to PDF

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

string inputFile = "YOUR_DOCUMENT_DIRECTORY/sample.docx";
string outputFolder = "path/to/output/directory";
string outputFile = Path.Combine(outputFolder, "converted.pdf");

var loadOptions = new WordProcessingLoadOptions
{
    Password = "12345"
};

using (Converter converter = new Converter(inputFile, () => loadOptions))
{
    var convertOptions = new PdfConvertOptions();
    converter.Convert(outputFile, convertOptions);
}

Explanation: This code demonstrates converting a DOCX file to PDF. It initializes the Converter class with input and load options, then performs conversion using PdfConvertOptions.
