virtual Document { get; }	Gets the document to which this node belongs.
FieldType { get; }	Returns the type of the field.
Font { get; }	Provides access to the font formatting of this object.
virtual IsComposite { get; }	Returns `true` if this node can contain other nodes.
IsDeleteRevision { get; }	Returns true if this object was deleted in Microsoft Word while change tracking was enabled.
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.
IsFormatRevision { get; }	Returns true if formatting of the object was changed in Microsoft Word while change tracking was enabled.
IsInsertRevision { get; }	Returns true if this object was inserted in Microsoft Word while change tracking was enabled.
IsLocked { get; set; }	Gets or sets whether the parent field is locked (should not recalculate its result).
IsMoveFromRevision { get; }	Returns `true` if this object was moved (deleted) in Microsoft Word while change tracking was enabled.
IsMoveToRevision { get; }	Returns `true` if this object was moved (inserted) in Microsoft Word while change tracking was enabled.
NextSibling { get; }	Gets the node immediately following this node.
override NodeType { get; }	Returns FieldSeparator.
ParentNode { get; }	Gets the immediate parent of this node.
ParentParagraph { get; }	Retrieves the parent `Paragraph` of this node.
PreviousSibling { get; }	Gets the node immediately preceding this node.
Range { get; }	Returns a `Range` object that represents the portion of a document that is contained in this node.

Methods

Name	Description
override Accept(DocumentVisitor)	Accepts a visitor.
Clone(bool)	Creates a duplicate of the node.
GetAncestor(NodeType)	Gets the first ancestor of the specified `NodeType`.
GetAncestor(Type)	Gets the first ancestor of the specified object type.
GetField()	Returns a field for the field char.
override GetText()	Gets the special character that this node represents.
NextPreOrder(Node)	Gets next node according to the pre-order tree traversal algorithm.
PreviousPreOrder(Node)	Gets the previous node according to the pre-order tree traversal algorithm.
Remove()	Removes itself from the parent.
ToString(SaveFormat)	Exports the content of the node into a string in the specified format.
ToString(SaveOptions)	Exports the content of the node into a string using the specified save options.

Remarks

FieldSeparator is an inline-level node and represented by the FieldSeparatorChar control character in the document.

FieldSeparator can only be a child of Paragraph.

A complete field in a Microsoft Word document is a complex structure consisting of a field start character, field code, field separator character, field result and field end character. Some fields only have field start, field code and field end.

To easily insert a new field into a document, use the InsertField method.

Examples

Shows how to work with a collection of fields.

public void FieldCollection()
{
    Document doc = new Document();
    DocumentBuilder builder = new DocumentBuilder(doc);

    builder.InsertField(" DATE \\@ \"dddd, d MMMM yyyy\" ");
    builder.InsertField(" TIME ");
    builder.InsertField(" REVNUM ");
    builder.InsertField(" AUTHOR  \"John Doe\" ");
    builder.InsertField(" SUBJECT \"My Subject\" ");
    builder.InsertField(" QUOTE \"Hello world!\" ");
    doc.UpdateFields();

    FieldCollection fields = doc.Range.Fields;

    Assert.That(fields.Count, Is.EqualTo(6));

    // Iterate over the field collection, and print contents and type
    // of every field using a custom visitor implementation.
    FieldVisitor fieldVisitor = new FieldVisitor();

    using (IEnumerator<Field> fieldEnumerator = fields.GetEnumerator())
    {
        while (fieldEnumerator.MoveNext())
        {
            if (fieldEnumerator.Current != null)
            {
                fieldEnumerator.Current.Start.Accept(fieldVisitor);
                fieldEnumerator.Current.Separator?.Accept(fieldVisitor);
                fieldEnumerator.Current.End.Accept(fieldVisitor);
            }
            else
            {
                Console.WriteLine("There are no fields in the document.");
            }
        }
    }

    Console.WriteLine(fieldVisitor.GetText());
