How to save a document in RTF format C# and VB.Net

How to save a document in RTF format C# and VB.Net

  1. Save to a file:
    
                // The file format will be detected automatically from the file extension: ".rtf".
                dc.Save(@"d:\Book.rtf");
    

    To not rely on the file extension and guarantee that the file contents is really RTF, you may specify RtfSaveOptions as 2nd parameter.

    
    dc.Save(@"d:\Book.rtf", new RtfSaveOptions());
    

    In RtfSaveOptions you can also set various options which affects to the saving process.

  2. Save to a Stream:
                // Let's save our document to a MemoryStream.
                using (MemoryStream ms = new MemoryStream())
                {
                    dc.Save(ms, new RtfSaveOptions());
                }
