Filling Word template fields with C#
Solution 1
Are you using legacy forms? When you add a legacy form field to a Word doc, under Properties > Field Settings there is a Bookmark which is basically the name of the field. By default, a legacy text field will have a Bookmark of "Text1", "Text2", etc.
So in VBA:
ActiveDocument.FormFields("Text1").Result = "asdf"
In your case it might be (C#):
doc.FormFields["Text1"].Result = "asdf"
Or you could simply write a loop that scans the list of fields and looks for a given name (pseudo-VB):
Function GetFieldByName(name As String) As Field
Dim i
For i = 0 to fields.count - 1
If fields(i).Name = name Then Return fields(i)
Next
Return Nothing
End Function
If you're using the newer form field controls where you can set a Tag and automate with VSTO (C#):
doc.SelectContentControlsByTag("Address")[1].Range.Text = "asdf"

Solution 2
One good way to do it is to, at each place in the template you would like to add text later, place a bookmark (Insert -> Links -> Bookmark). To use them from your code, you would access each bookmark by its name, see this example:
Word._Application wApp = new Word.Application();
Word.Documents wDocs = wApp.Documents;
Word._Document wDoc = wDocs.Open(ref "file_path_here", ReadOnly:false);
wDoc.Activate();
Word.Bookmarks wBookmarks = wDoc.Bookmarks;
Word.Bookmark wBookmark = wBookmarks["Bookmark_name"];
Word.Range wRange = wBookmark.Range;
wRange.Text = valueToSetInTemplate;

Currently, if I create a Word Document Template with fields, and then fill them using C#, I do it similar to this...
object missing = Type.Missing; Word.Application app = new Word.Application(); Word.Document doc = app.Documents.Open("file.doc", ref missing, true); Word.FormFields fields = doc.FormFields; fields[2].Result = "foo" fields[3].Result = "bar"
Is there a better way to reference the fields?
I notice when creating the template I can add a Title and a Tag to the field, but I haven't found a way to reference those properties. It would be nice to be able to name fields and reference them directly, instead of just counting and figuring out which field I am on.

erosebe over 9 yearsHey, alright. That last thing you mentioned is what would work for me. I guess I was stuck looking in the Fields and didn't know about ContentControls. Thanks.

perry over 9 yearsNo problem! You gave me enough rep to vote up comments now, so thanks for that.

erosebe over 9 yearsHey, just for the record, your example code has a type. The (1) should be [1]. And it really is 1 based, instead of 0, which is kinda odd.

perry over 9 yearsI updated the answer to clarify, it's one of the very minor differences between VB and C#. VB is lovely :)
