Shows how save a web page as a .docx file.
const string url = "";

using (WebClient client = new WebClient()) 
    using (MemoryStream stream = new MemoryStream(client.DownloadData(url)))
        // The URL is used again as a baseUri to ensure that any relative image paths are retrieved correctly.
        LoadOptions options = new LoadOptions(LoadFormat.Html, "", url);

        // Load the HTML document from stream and pass the LoadOptions object.
        Document doc = new Document(stream, options);

        // At this stage, we can read and edit the document's contents and then save it to the local file system.
        doc.Save(ArtifactsDir + "Document.InsertHtmlFromWebPage.docx");
Shows how to specify a base URI when opening an html document.
// Suppose we want to load an .html document that contains an image linked by a relative URI
// while the image is in a different location. In that case, we will need to resolve the relative URI into an absolute one.
// We can provide a base URI using an HtmlLoadOptions object. 
HtmlLoadOptions loadOptions = new HtmlLoadOptions(LoadFormat.Html, "", ImageDir);

Assert.AreEqual(LoadFormat.Html, loadOptions.LoadFormat);

Document doc = new Document(MyDir + "Missing image.html", loadOptions);

// While the image was broken in the input .html, our custom base URI helped us repair the link.
Shape imageShape = (Shape)doc.GetChildNodes(NodeType.Shape, true)[0];

// This output document will display the image that was missing.
doc.Save(ArtifactsDir + "HtmlLoadOptions.BaseUri.docx");
Shows how to use the FileFormatUtil methods to detect the format of a document.
// Load a document from a file that is missing a file extension, and then detect its file format.
using (FileStream docStream = File.OpenRead(MyDir + "Word document with missing file extension"))
    FileFormatInfo info = FileFormatUtil.DetectFileFormat(docStream);
    LoadFormat loadFormat = info.LoadFormat;

    Assert.AreEqual(LoadFormat.Doc, loadFormat);

    // Below are two methods of converting a LoadFormat to its corresponding SaveFormat.
    // 1 -  Get the file extension string for the LoadFormat, then get the corresponding SaveFormat from that string:
    string fileExtension = FileFormatUtil.LoadFormatToExtension(loadFormat);
    SaveFormat saveFormat = FileFormatUtil.ExtensionToSaveFormat(fileExtension);

    // 2 -  Convert the LoadFormat directly to its SaveFormat:
    saveFormat = FileFormatUtil.LoadFormatToSaveFormat(loadFormat);

    // Load a document from the stream, and then save it to the automatically detected file extension.
    Document doc = new Document(docStream);

    Assert.AreEqual(".doc", FileFormatUtil.SaveFormatToExtension(saveFormat));

    doc.Save(ArtifactsDir + "File.SaveToDetectedFileFormat" + FileFormatUtil.SaveFormatToExtension(saveFormat));
