## Properties

| Name | Description |
| --- | --- |
| [DisplayResult](../../aspose.words.fields/field/displayresult/) { get; } | Gets the text that represents the displayed field result. |
| [End](../../aspose.words.fields/field/end/) { get; } | Gets the node that represents the field end. |
| [EntryLevel](../../aspose.words.fields/fieldtc/entrylevel/) { get; set; } | Gets or sets the level of the entry. |
| [Format](../../aspose.words.fields/field/format/) { get; } | Gets a [`FieldFormat`](../fieldformat/) object that provides typed access to field's formatting. |
| [IsDirty](../../aspose.words.fields/field/isdirty/) { get; set; } | Gets or sets whether the current result of the field is no longer correct (stale) due to other modifications made to the document. |
| [IsLocked](../../aspose.words.fields/field/islocked/) { get; set; } | Gets or sets whether the field is locked (should not recalculate its result). |
| [LocaleId](../../aspose.words.fields/field/localeid/) { get; set; } | Gets or sets the LCID of the field. |
| [OmitPageNumber](../../aspose.words.fields/fieldtc/omitpagenumber/) { get; set; } | Gets or sets whether page number in TOC should be omitted for this field. |
| [Result](../../aspose.words.fields/field/result/) { get; set; } | Gets or sets text that is between the field separator and field end. |
| [Separator](../../aspose.words.fields/field/separator/) { get; } | Gets the node that represents the field separator. Can be `null`. |
| [Start](../../aspose.words.fields/field/start/) { get; } | Gets the node that represents the start of the field. |
| [Text](../../aspose.words.fields/fieldtc/text/) { get; set; } | Gets or sets the text of the entry. |
| virtual [Type](../../aspose.words.fields/field/type/) { get; } | Gets the Microsoft Word field type. |
| [TypeIdentifier](../../aspose.words.fields/fieldtc/typeidentifier/) { get; set; } | Gets or sets a type identifier for this field (which is typically a letter). |

## Methods

| Name | Description |
| --- | --- |
| [GetFieldCode](../../aspose.words.fields/field/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](../../aspose.words.fields/field/getfieldcode/)(*bool*) | Returns text between field start and field separator (or field end if there is no separator). |
| virtual [Remove](../../aspose.words.fields/field/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`. |
| [Unlink](../../aspose.words.fields/field/unlink/)() | Performs the field unlink. |
| [Update](../../aspose.words.fields/field/update/)() | Performs the field update. Throws if the field is being updated already. |
| [Update](../../aspose.words.fields/field/update/)(*bool*) | Performs a field update. Throws if the field is being updated already. |

## Remarks

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.

```csharp
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.That(fieldToc.GetFieldCode(), Is.EqualTo(" TOC  \\f A \\l 1-3"));

// 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.That(doc.Range.Fields[1].GetFieldCode(), Is.EqualTo(" TC  \"TC field 1\" \\n \\f A \\l 1"));

// 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");
```

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

```csharp
/// <summary>
/// Use a document builder to insert a TC field.
/// </summary>
public void InsertTocEntry(DocumentBuilder builder, string text, string typeIdentifier, string entryLevel)
{
    FieldTC fieldTc = (FieldTC)builder.InsertField(FieldType.FieldTOCEntry, true);
    fieldTc.OmitPageNumber = true;
    fieldTc.Text = text;
    fieldTc.TypeIdentifier = typeIdentifier;
    fieldTc.EntryLevel = entryLevel;
}
```
