Word/Office Automation - How to retrieve selected value from a Drop-down form field - ms-word

Question

I am trying to retrieve the value of all fields in a word document via office automation using c#. The code is shown below however if the field is a drop-down then the value of the range text is always empty even though I know it is populated. If it is a simple text field then I can see the range text. How do I get the selected drop down item? I feel there must be something quite simple that I'm doing wrong...
private void OpenWordDoc(string filename) {
Microsoft.Office.Interop.Word.Application app = new Microsoft.Office.Interop.Word.Application();
Document doc = app.Documents.Open(filename, ReadOnly: true, Visible: false);
foreach (Field f in doc.Fields) {
string bookmarkName = "??";
if (f.Code.Bookmarks.Count > 0) {
bookmarkName = f.Code.Bookmarks[1].Name; // have to start at 1 because it is vb style!
}
Debug.WriteLine(bookmarkName);
Debug.WriteLine(f.Result.Text); // This is empty when it is a drop down field
}
doc.Close();
app.Quit();
}

Answer 1

Aha - If I scan through FormFields instead of Fields then all is good...
foreach (FormField f in doc.FormFields) {
string bookmarkName = "??";
if (ff.Range.Bookmarks.Count > 0) {
bookmarkName = ff.Range.Bookmarks[1].Name; // have to start at 1 because it is vb style!
}
Debug.WriteLine(bookmarkName);
Debug.WriteLine(ff.Result); // This is empty when it is a drop down field
}
Problem solved. Phew.
