Examples

Shows how to use NUMCHARS, NUMWORDS, NUMPAGES and PAGE fields to track the size of our documents.

Document doc = new Document(MyDir + "Paragraphs.docx");
DocumentBuilder builder = new DocumentBuilder(doc);

builder.MoveToHeaderFooter(HeaderFooterType.FooterPrimary);
builder.ParagraphFormat.Alignment = ParagraphAlignment.Center;

// Below are three types of fields that we can use to track the size of our documents.
// 1 -  Track the character count with a NUMCHARS field:
FieldNumChars fieldNumChars = (FieldNumChars)builder.InsertField(FieldType.FieldNumChars, true);       
builder.Writeln(" characters");

// 2 -  Track the word count with a NUMWORDS field:
FieldNumWords fieldNumWords = (FieldNumWords)builder.InsertField(FieldType.FieldNumWords, true);
builder.Writeln(" words");

// 3 -  Use both PAGE and NUMPAGES fields to display what page the field is on,
// and the total number of pages in the document:
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());

// These fields will not maintain accurate values in real time
// while we edit the document programmatically using Aspose.Words, or in Microsoft Word.
// We need to update them every we need to see an up-to-date value. 
doc.UpdateFields();
doc.Save(ArtifactsDir + "Field.NUMCHARS.NUMWORDS.NUMPAGES.PAGE.docx");
