Use C# Code to Extract Data from Database

string connectionString = string.Format("Provider=System.Data.Sqlite;Data Source={0};Version=3;", "database.db");
// create an instance of Parser class to extract tables from the database
// as filePath connection parameters are passed; LoadOptions is set to Database file format
using (Parser parser = new Parser(connectionString, new LoadOptions(FileFormat.Database)))
{
    // check if text extraction is supported
    if (!parser.Features.Text)
    {
        Console.WriteLine("Text extraction isn't supported.");
        return;
    }
    // check if toc extraction is supported
    if (!parser.Features.Toc)
    {
        Console.WriteLine("Toc extraction isn't supported.");
        return;
    }
    // get a list of tables
    IEnumerable<TocItem> toc = parser.GetToc();
    // iterate over tables
    foreach (TocItem i in toc)
    {
        // print the table name
        Console.WriteLine(i.Text);
        // extract a table content as a text
        using (TextReader reader = parser.GetText(i.PageIndex.Value))
        {
            Console.WriteLine(reader.ReadToEnd());
        }
    }
}

Extract all Images and Save them in PNG Format via C# Code

// create an instance of Parser class
using (Parser parser = new Parser(Constants.SampleZip))
{
    // extract images from document
    IEnumerable<PageImageArea> images = parser.GetImages();
    // check if images extraction is supported
    if (images == null)
    {
        Console.WriteLine("Page images extraction isn't supported");
        return;
    }
    // create the options to save images in PNG format
    ImageOptions options = new ImageOptions(ImageFormat.Png);
    int imageNumber = 0;
    // iterate over images
    foreach (PageImageArea image in images)
    {
        // save the image to the png file
        image.Save(imageNumber.ToString() + ".png", options);
        imageNumber++;
    }
}
