Properties

Name	Description
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.
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.
IsInKilobytes { get; set; }	Gets or sets whether to display the file size in kilobytes.
IsInMegabytes { get; set; }	Gets or sets whether to display the file size in megabytes.
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.

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`.
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.

Remarks

Retrieves the size of the current document’s file or 0 if the size cannot be determined.

In the current implementation, uses the OriginalFileName property to retrieve the file name used to determine the file size.

Examples

Shows how to display the file size of a document with a FILESIZE field.

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

Assert.AreEqual(18105, doc.BuiltInDocumentProperties.Bytes);

DocumentBuilder builder = new DocumentBuilder(doc);
builder.MoveToDocumentEnd();
builder.InsertParagraph();

// Below are three different units of measure
// with which FILESIZE fields can display the document's file size.
// 1 -  Bytes:
FieldFileSize field = (FieldFileSize)builder.InsertField(FieldType.FieldFileSize, true);
field.Update();

Assert.AreEqual(" FILESIZE ", field.GetFieldCode());
Assert.AreEqual("18105", field.Result);

// 2 -  Kilobytes:
builder.InsertParagraph();
field = (FieldFileSize)builder.InsertField(FieldType.FieldFileSize, true);
field.IsInKilobytes = true;
field.Update();

Assert.AreEqual(" FILESIZE  \\k", field.GetFieldCode());
Assert.AreEqual("18", field.Result);

// 3 -  Megabytes:
builder.InsertParagraph();
field = (FieldFileSize)builder.InsertField(FieldType.FieldFileSize, true);
field.IsInMegabytes = true;
field.Update();

Assert.AreEqual(" FILESIZE  \\m", field.GetFieldCode());
Assert.AreEqual("0", field.Result);

// To update the values of these fields while editing in Microsoft Word,
// we must first save the changes, and then manually update these fields.
doc.Save(ArtifactsDir + "Field.FILESIZE.docx");
