Examples

Shows how to work with REVNUM fields.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

builder.Write("Current revision #");

// Insert a REVNUM field, which displays the document's current revision number property.
FieldRevNum field = (FieldRevNum)builder.InsertField(FieldType.FieldRevisionNum, true);

Assert.AreEqual(" REVNUM ", field.GetFieldCode());
Assert.AreEqual("1", field.Result);
Assert.AreEqual(1, doc.BuiltInDocumentProperties.RevisionNumber);

// This property counts how many times a document has been saved in Microsoft Word,
// and is unrelated to tracked revisions. We can find it by right clicking the document in Windows Explorer
// via Properties -> Details. We can update this property manually.
doc.BuiltInDocumentProperties.RevisionNumber++;
field.Update();

Assert.AreEqual("2", field.Result);
