Examples

The following example illustrates how to unlink the specified field.

  //Creates an instance of WordDocument class
  WordDocument document = new WordDocument();
  //Adds a new section into the Word Document
  IWSection section = document.AddSection();
  //Adds a new paragraph into Word document and appends text into paragraph
  IWParagraph paragraph = section.AddParagraph();
  paragraph.AppendText("Today's Date: ");
  //Adds the new Date field in Word document with field name and its type
  WField field = paragraph.AppendField("Date", FieldType.FieldDate) as WField;
  //Updates the field
  field.Update();
  //Unlink the field
  field.Unlink();
  //Saves the document in the given name and format
  document.Save("Sample.docx", FormatType.Docx);
  //Releases the resources occupied by WordDocument instance
  document.Close();

  'Creates an instance of WordDocument class
  Dim document As WordDocument = New WordDocument()
  'Adds a new section into the Word Document
  Dim section As IWSection = document.AddSection()
  'Adds a new paragraph into Word document and appends text into paragraph
  Dim paragraph As IWParagraph = section.AddParagraph()
  paragraph.AppendText("Today's Date: ")
  'Adds the new Date field in Word document with field name and its type
  Dim field As WField = CType(paragraph.AppendField("Date", FieldType.FieldDate), WField)
  'Updates the field
  field.Update()
  'Unlink the field
  field.Unlink()
  'Saves the document in the given name and format
