FieldFileName()The default constructor.


DisplayResult { get; }Gets the text that represents the displayed field result.
End { get; }Gets the node that represents the field end.
Format { get; }Gets a FieldFormat object that provides typed access to field’s formatting.
IncludeFullPath { get; set; }Gets or sets whether to include the full file path name.
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 { get; set; }Gets or sets whether the field is locked (should not recalculate its result).
LocaleId { get; set; }Gets or sets the LCID of the field.
Result { get; set; }Gets or sets text that is between the field separator and field end.
Separator { get; }Gets the node that represents the field separator. Can be null.
Start { get; }Gets the node that represents the start of the field.
virtual Type { get; }Gets the Microsoft Word field type.


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.
Unlink()Performs the field unlink.
Update()Performs the field update. Throws if the field is being updated already.
Update(bool)Performs a field update. Throws if the field is being updated already.


Retrieves the name of the current document from its storage location.

In the current implementation, uses the OriginalFileName property to retrieve the file name. If the document was loaded from a stream or created blank, uses the name of the file that is being saved to (if known).


Shows how to use FieldOptions to override the default value for the FILENAME field.

Document doc = new Document(MyDir + "Document.docx");
DocumentBuilder builder = new DocumentBuilder(doc);


// This FILENAME field will display the local system file name of the document we loaded.
FieldFileName field = (FieldFileName)builder.InsertField(FieldType.FieldFileName, true);

Assert.AreEqual(" FILENAME ", field.GetFieldCode());
Assert.AreEqual("Document.docx", field.Result);


// By default, the FILENAME field shows the file's name, but not its full local file system path.
// We can set a flag to make it show the full file path.
field = (FieldFileName)builder.InsertField(FieldType.FieldFileName, true);
field.IncludeFullPath = true;

Assert.AreEqual(MyDir + "Document.docx", field.Result);

// We can also set a value for this property to
// override the value that the FILENAME field displays.
doc.FieldOptions.FileName = "FieldOptions.FILENAME.docx";

Assert.AreEqual(" FILENAME  \\p", field.GetFieldCode());
Assert.AreEqual("FieldOptions.FILENAME.docx", field.Result);

doc.Save(ArtifactsDir + doc.FieldOptions.FileName);
