Use DocStream to provide access to binary document data for this document.
dtSearch treats the contents of DocStream as if it were a file found on disk, so it can be any binary document format that dtSearch supports, such as a PDF file, DOC file, XLS file, etc.
DocStream can be any .NET class derived from System.IO.Stream, as long as the class supports Read() and Seek() and returns true from both CanRead and CanSeek.
The FileConverter object provides three ways to return a binary document: InputStream (any .NET Stream object), InputBytes (a byte array), and InputFile (a disk file). Only one of these can be used for each document.
