Fields in Microsoft Word documents consist of a field code and a field result. The field code is like a formula and the field result is the value that the formula produces. The field code may also contain field switches that are additional instructions to perform a specific action.

You can switch between displaying field codes and results in your document in Microsoft Word using the keyboard shortcut Alt+F9. Field codes appear between curly braces ( { } ).

Use InsertField to create fields in the document. You need to specify a field type, field code and field value. If you are not sure about the particular field code syntax, create the field in Microsoft Word first and switch to see its field code.

Example DocumentBuilderInsertField

Inserts a merge field into a document using DocumentBuilder.

[C#]

Document doc = new Document();

DocumentBuilder builder = new DocumentBuilder(doc);

builder.InsertField(@"MERGEFIELD MyFieldName \* MERGEFORMAT", "");

[Visual Basic]

Dim doc As Document = New Document()

Dim builder As DocumentBuilder = New DocumentBuilder(doc)

builder.InsertField("MERGEFIELD MyFieldName \* MERGEFORMAT", "")

[Java]

Document doc = new Document();

DocumentBuilder builder = new DocumentBuilder(doc);

builder.insertField("MERGEFIELD MyFieldName \\* MERGEFORMAT", "");
