Examples

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));
}
