Examples

In some cases it's necessary to define FileFormat. Both for special cases (databases, email server) and for detecting file types by the content:

C#
// Create an instance of Parser class for markdown document
using (Parser parser = new Parser(stream, new LoadOptions(FileFormat.Markup)))
{
    // Check if text extraction is supported
    if (!parser.Features.Text)
    {
        Console.WriteLine("Text extraction isn't supported.");
        return;
    }
    using (TextReader reader = parser.GetText())
    {
        // Print the document text
        // Markdown is detected; text without special symbols is printed
        Console.WriteLine(reader.ReadToEnd());
    }
}

The document password is passed by LoadOptions class:

C#
try
{
    // Create an instance of Parser class with the password:
    using (Parser parser = new Parser(filePath, new LoadOptions(password)))
    {
        // Check if text extraction is supported
        if (!parser.Features.Text)
        {
            Console.WriteLine("Text extraction isn't supported.");
            return;
        }
        // Print the document text
        using (TextReader reader = parser.GetText())
        {
            Console.WriteLine(reader.ReadToEnd());
        }
    }
}
catch (InvalidPasswordException)
{
    // Print the message if the password is incorrect or empty
    Console.WriteLine("Invalid password");
}
