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.

Examples

Shows how to create right-to-left language-compatible lists with BIDIOUTLINE fields.

Document doc = new Document();
DocumentBuilder builder = new DocumentBuilder(doc);

// The BIDIOUTLINE field numbers paragraphs like the AUTONUM/LISTNUM fields,
// but is only visible when a right-to-left editing language is enabled, such as Hebrew or Arabic.
// The following field will display ".1", the RTL equivalent of list number "1.".
FieldBidiOutline field = (FieldBidiOutline)builder.InsertField(FieldType.FieldBidiOutline, true);
builder.Writeln("שלום");

Assert.AreEqual(" BIDIOUTLINE ", field.GetFieldCode());

// Add two more BIDIOUTLINE fields, which will display ".2" and ".3".
builder.InsertField(FieldType.FieldBidiOutline, true);
builder.Writeln("שלום");
builder.InsertField(FieldType.FieldBidiOutline, true);
builder.Writeln("שלום");

// Set the horizontal text alignment for every paragraph in the document to RTL.
foreach (Paragraph para in doc.GetChildNodes(NodeType.Paragraph, true))
{
    para.ParagraphFormat.Bidi = true;
}

// If we enable a right-to-left editing language in Microsoft Word, our fields will display numbers.
// Otherwise, they will display "###".
doc.Save(ArtifactsDir + "Field.BIDIOUTLINE.docx");

Shows how some older Microsoft Word fields such as SHAPE and EMBED are handled during loading.

// Open a document that was created in Microsoft Word 2003.
Document doc = new Document(MyDir + "Legacy fields.doc");

// If we open the Word document and press Alt+F9, we will see a SHAPE and an EMBED field.
// A SHAPE field is the anchor/canvas for an AutoShape object with the "In line with text" wrapping style enabled.
// An EMBED field has the same function, but for an embedded object,
// such as a spreadsheet from an external Excel document.
// However, these fields will not appear in the document's Fields collection.
Assert.AreEqual(0, doc.Range.Fields.Count);

// These fields are supported only by old versions of Microsoft Word.
// The document loading process will convert these fields into Shape objects,
// which we can access in the document's node collection.
NodeCollection shapes = doc.GetChildNodes(NodeType.Shape, true);
Assert.AreEqual(3, shapes.Count);

// The first Shape node corresponds to the SHAPE field in the input document,
// which is the inline canvas for the AutoShape.
Shape shape = (Shape)shapes[0];
Assert.AreEqual(ShapeType.Image, shape.ShapeType);

// The second Shape node is the AutoShape itself.
shape = (Shape)shapes[1];
Assert.AreEqual(ShapeType.Can, shape.ShapeType);

// The third Shape is what was the EMBED field that contained the external spreadsheet.
shape = (Shape)shapes[2];
Assert.AreEqual(ShapeType.OleObject, shape.ShapeType);
