// Add a paragraph and get its range:
var rng = doc.Body.Paragraphs.Add().GetRange();
// Add a static text:
rng.Runs.Add("Today is ");
// Add a complex field with "IF" instruction. We also provide
// a pre-calculated value for the sake of PDF export, as DsWord
// does not yet support field calculation - see DateAndTime.
// Note also that because the code field will not be calculated
// in the PDF export, the "NOT " won't be bold in it:
var val = Util.TimeNow().DayOfYear == 1 ? "" : "NOT ";
var f = rng.ComplexFields.Add("IF ", val);
// Add a complex field with "DATE" instruction:
f.GetCodeRange().ComplexFields.Add(" DATE \\@ \"M-d\" ");
// Add additional instruction to the "IF" field to compare the nested
// DATE field result with "1-1" and return "NOT " if it is true,
// also make the "NOT " bold if visible:
f.CodeFields.Add("<> \"1-1\" \"NOT \"").ParentRun.Font.Bold = true;
// Add a static text:
rng.Runs.Add("New Year's Day.");
// Done:
