Fields

Fields are placeholders, such as page reference numbers, replaced by their corresponding values when the document is rendered for display or print.

Following example demonstrates how to create fields of different field types and with various field arguments and switches.

Output file type

C#
VB.NET

using GemBox.Document;

class Program
{
    static void Main()
    {
        // If using Professional version, put your serial key below.
        ComponentInfo.SetLicense("FREE-LIMITED-KEY");

        DocumentModel document = new DocumentModel();

        document.Sections.Add(
            new Section(document,
                new Paragraph(document, "Press Alt + F9 to see field codes!"),
                new Paragraph(document,
                    new Run(document, "Date: "),
                    // { DATE }
                    new Field(document, FieldType.Date),
                    new SpecialCharacter(document, SpecialCharacterType.LineBreak),
                    new Run(document, "Date (formatted): "),
                    // { DATE \@ "dddd, MMMM dd, yyyy"  \* MERGEFORMAT }
                    new Field(document, FieldType.Date, "\\@ \"dddd, MMMM dd, yyyy\"  \\* MERGEFORMAT"),
                    new SpecialCharacter(document, SpecialCharacterType.LineBreak),
                    new Run(document, "Date & Time (formatted): "),

                    new Field(document, FieldType.Date, " \\@ \"M/d/yyyy h:mm:ss am/pm\"  \\* MERGEFORMAT"))));

        document.Save("Fields.%OutputFileType%");
    }
}
