## Footnote::get_ReferenceMark method


Gets/sets custom reference mark to be used for this footnote. Default value is **empty string**, meaning auto-numbered footnotes are used.

```cpp
System::String Aspose::Words::Notes::Footnote::get_ReferenceMark() const
```

## Remarks


If this property is set to **empty string** or **null**, then [IsAuto](../get_isauto/) property will automatically be set to **true**, if set to anything else then [IsAuto](../get_isauto/) will be set to **false**.

RTF-format can only store 1 symbol as custom reference mark, so upon export only the first symbol will be written others will be discard.

## Examples



Shows how to insert and customize footnotes. 
```cpp
auto doc = System::MakeObject<Aspose::Words::Document>();
auto builder = System::MakeObject<Aspose::Words::DocumentBuilder>(doc);

// Add text, and reference it with a footnote. This footnote will place a small superscript reference
// mark after the text that it references and create an entry below the main body text at the bottom of the page.
// This entry will contain the footnote's reference mark and the reference text,
// which we will pass to the document builder's "InsertFootnote" method.
builder->Write(u"Main body text.");
System::SharedPtr<Aspose::Words::Notes::Footnote> footnote = builder->InsertFootnote(FootnoteType::Footnote, u"Footnote text.");

// If this property is set to "true", then our footnote's reference mark
// will be its index among all the section's footnotes.
// This is the first footnote, so the reference mark will be "1".
ASSERT_TRUE(footnote->get_IsAuto());

// We can move the document builder inside the footnote to edit its reference text.
builder->MoveTo(footnote->get_FirstParagraph());
builder->Write(u" More text added by a DocumentBuilder.");
builder->MoveToDocumentEnd();

ASSERT_EQ(u"\u0002 Footnote text. More text added by a DocumentBuilder.", footnote->GetText().Trim());

builder->Write(u" More main body text.");
footnote = builder->InsertFootnote(FootnoteType::Footnote, u"Footnote text.");

// We can set a custom reference mark which the footnote will use instead of its index number.
footnote->set_ReferenceMark(u"RefMark");

ASSERT_FALSE(footnote->get_IsAuto());

// A bookmark with the "IsAuto" flag set to true will still show its real index
// even if previous bookmarks display custom reference marks, so this bookmark's reference mark will be a "3".
builder->Write(u" More main body text.");
footnote = builder->InsertFootnote(FootnoteType::Footnote, u"Footnote text.");

ASSERT_TRUE(footnote->get_IsAuto());

doc->Save(get_ArtifactsDir() + u"InlineStory.AddFootnote.docx");
```
