Saving FlowDocument to SQL Server

Question

I need to save WPF FlowDocuments to SQL Server. What is the best format for doing that? String? Blob? Does it matter in a document less than 5K words or so?

Answer 1

You can serialize FlowDocument using the TextRange class. You can even use the RTF format. Saving:

FlowDocument docToSave; // Lets suppose this var is initialized.
var tr = new TextRange(docToSave.ContentStart,docToSave.ContentEnd);
var dst = new MemoryStream();
tr.Save(dst, DataFormats.Rtf);
dst.Close();

And loading:

FlowDocument docToLoad = new FlowDocument();
var tr = new TextRange(docToLoad.ContentStart,docToLoad.ContentEnd);
Stream src; // Lets suppose it is initialized.
tr.Load(src, DataFormats.Rtf);
src.Close();
