Methods

Name	Description
GetFieldCode()	Returns text between field start and field separator (or field end if there is no separator). Both field code and field result of child fields are included.
GetFieldCode(bool)	Returns text between field start and field separator (or field end if there is no separator).
Remove()	Removes the field from the document. Returns a node right after the field. If the field’s end is the last child of its parent node, returns its parent paragraph. If the field is already removed, returns `null`.

Defines the text and page number for a table of contents (including a table of figures) entry, which is used by a TOC field.

Examples

Shows how to insert a TOC field, and filter which TC fields end up as entries.

public void FieldTocEntryIdentifier()
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    // Insert a TOC field, which will compile all TC fields into a table of contents.
    FieldToc fieldToc = (FieldToc)builder.InsertField(FieldType.FieldTOC, true);

    // Configure the field only to pick up TC entries of the "A" type, and an entry-level between 1 and 3.
    fieldToc.EntryIdentifier = "A";
    fieldToc.EntryLevelRange = "1-3";

    Assert.AreEqual(" TOC  \\f A \\l 1-3", fieldToc.GetFieldCode());

    // These two entries will appear in the table.
    builder.InsertBreak(BreakType.PageBreak);
    InsertTocEntry(builder, "TC field 1", "A", "1");
    InsertTocEntry(builder, "TC field 2", "A", "2");

    Assert.AreEqual(" TC  \"TC field 1\" \\n \\f A \\l 1", doc.Range.Fields[1].GetFieldCode());

    // This entry will be omitted from the table because it has a different type from "A".
    InsertTocEntry(builder, "TC field 3", "B", "1");

    // This entry will be omitted from the table because it has an entry-level outside of the 1-3 range.
    InsertTocEntry(builder, "TC field 4", "A", "5");

    doc.UpdateFields();
    doc.Save(ArtifactsDir + "Field.TC.docx");
}
