## Methods

| Method | Description |
| --- | --- |
| [get_DisplayResult](../field/get_displayresult/)() | Gets the text that represents the displayed field result. |
| [get_End](../field/get_end/)() const | Gets the node that represents the field end. |
| [get_FieldEnd](../field/get_fieldend/)() const | Gets the node that represents the field end. |
| [get_FieldStart](../field/get_fieldstart/)() const | Gets the node that represents the start of the field. |
| [get_FileName](./get_filename/)() | Gets or sets the name of the file to include when generating a table of contents, table of authorities, or index. |
| [get_Format](../field/get_format/)() | Gets a [FieldFormat](../fieldformat/) object that provides typed access to field's formatting. |
| [get_IsDirty](../field/get_isdirty/)() | Gets or sets whether the current result of the field is no longer correct (stale) due to other modifications made to the document. |
| [get_IsLocked](../field/get_islocked/)() | Gets or sets whether the field is locked (should not recalculate its result). |
| [get_IsPathRelative](./get_ispathrelative/)() | Gets or sets whether the path is relative to the current document. |
| [get_LocaleId](../field/get_localeid/)() | Gets or sets the LCID of the field. |
| [get_Result](../field/get_result/)() | Gets or sets text that is between the field separator and field end. |
| [get_Separator](../field/get_separator/)() | Gets the node that represents the field separator. Can be **null**. |
| [get_Start](../field/get_start/)() const | Gets the node that represents the start of the field. |
| virtual [get_Type](../field/get_type/)() const | Gets the Microsoft Word field type. |
| [GetFieldCode](../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](../field/getfieldcode/)(bool) | Returns text between field start and field separator (or field end if there is no separator). |
| [GetType](./gettype/)() const override |  |
| [Is](./is/)(const System::TypeInfo\&) const override |  |
| virtual [Remove](../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**. |
| [set_FileName](./set_filename/)(const System::String\&) | Setter for [Aspose::Words::Fields::FieldRD::get_FileName](./get_filename/). |
| [set_IsDirty](../field/set_isdirty/)(bool) | Setter for [Aspose::Words::Fields::Field::get_IsDirty](../field/get_isdirty/). |
| [set_IsLocked](../field/set_islocked/)(bool) | Setter for [Aspose::Words::Fields::Field::get_IsLocked](../field/get_islocked/). |
| [set_IsPathRelative](./set_ispathrelative/)(bool) | Setter for [Aspose::Words::Fields::FieldRD::get_IsPathRelative](./get_ispathrelative/). |
| [set_LocaleId](../field/set_localeid/)(int32_t) | Setter for [Aspose::Words::Fields::Field::get_LocaleId](../field/get_localeid/). |
| [set_Result](../field/set_result/)(const System::String\&) | Setter for [Aspose::Words::Fields::Field::get_Result](../field/get_result/). |
| static [Type](./type/)() |  |
| [Unlink](../field/unlink/)() | Performs the field unlink. |
| [Update](../field/update/)() | Performs the field update. Throws if the field is being updated already. |
| [Update](../field/update/)(bool) | Performs a field update. Throws if the field is being updated already. |

## Examples



Shows to use the RD field to create a table of contents entries from headings in other documents. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>(doc);

// Use a document builder to insert a table of contents,
// and then add one entry for the table of contents on the following page.
builder->InsertField(FieldType::FieldTOC, true);
builder->InsertBreak(BreakType::PageBreak);
builder->get_CurrentParagraph()->get_ParagraphFormat()->set_StyleName(u"Heading 1");
builder->Writeln(u"TOC entry from within this document");

// Insert an RD field, which references another local file system document in its FileName property.
// The TOC will also now accept all headings from the referenced document as entries for its table.
auto field = System::ExplicitCast<Aspose::Words::Fields::FieldRD>(builder->InsertField(FieldType::FieldRefDoc, true));
field->set_FileName(get_ArtifactsDir() + u"ReferencedDocument.docx");

ASSERT_EQ(System::String::Format(u" RD  {0}ReferencedDocument.docx", get_ArtifactsDir().Replace(u"\\", u"\\\\")), field->GetFieldCode());

// Create the document that the RD field is referencing and insert a heading.
// This heading will show up as an entry in the TOC field in our first document.
auto referencedDoc = System::MakeObject<Aspose::Words::Document>();
auto refDocBuilder = System::MakeObject<Aspose::Words::DocumentBuilder>(referencedDoc);
refDocBuilder->get_CurrentParagraph()->get_ParagraphFormat()->set_StyleName(u"Heading 1");
refDocBuilder->Writeln(u"TOC entry from referenced document");
referencedDoc->Save(get_ArtifactsDir() + u"ReferencedDocument.docx");

doc->UpdateFields();
doc->Save(get_ArtifactsDir() + u"Field.RD.docx");
```
