Examples
Shows how to use NUMCHARS, NUMWORDS, NUMPAGES and PAGE fields to track the size of our documents.
// Open a document to which we want to add character/word/page counts
Document doc = new Document(MyDir + "Lists.PrintOutAllLists.doc");
DocumentBuilder builder = new DocumentBuilder(doc);

// Move the document builder to the footer, where we will store our fields
builder.MoveToHeaderFooter(HeaderFooterType.FooterPrimary);
builder.ParagraphFormat.Alignment = ParagraphAlignment.Center;

// Insert character and word counts
FieldNumChars fieldNumChars = (FieldNumChars)builder.InsertField(FieldType.FieldNumChars, true);       
builder.Writeln(" characters");
FieldNumWords fieldNumWords = (FieldNumWords)builder.InsertField(FieldType.FieldNumWords, true);
builder.Writeln(" words");

// Insert a "Page x of y" page count
builder.ParagraphFormat.Alignment = ParagraphAlignment.Right;
builder.Write("Page ");
FieldPage fieldPage = (FieldPage)builder.InsertField(FieldType.FieldPage, true);
builder.Write(" of ");
FieldNumPages fieldNumPages = (FieldNumPages)builder.InsertField(FieldType.FieldNumPages, true);

Assert.AreEqual(" NUMCHARS ", fieldNumChars.GetFieldCode());
Assert.AreEqual(" NUMWORDS ", fieldNumWords.GetFieldCode());
Assert.AreEqual(" NUMPAGES ", fieldNumPages.GetFieldCode());
Assert.AreEqual(" PAGE ", fieldPage.GetFieldCode());

doc.UpdateFields();
