Thanks for your inquiry. A field in a Word document is a complex structure consisting of multiple nodes that include field start, field code, field separator, field result and field end. Fields can be nested, contain rich content and span multiple paragraphs or sections in a document. The Field class is a “facade” object that provides properties and methods that allow to work with a field as a single object.
The Start, Separator and End properties point to the field start, separator and end nodes of the field respectively.
The content between the field start and separator is the field code. The content between the field separator and field end is the field result. The field code typically consists of one or more Run objects that specify instructions. The processing application is expected to execute the field code to calculate the field result.
Please use following method to get the field code of nested fields. Hope this helps you. Please let us know if you have any more queries.
private static string GetFieldCode(Aspose.Words.Fields.FieldStart fieldStart)
StringBuilder builder = new StringBuilder();
fieldStart.GetField().Result = "";
Node currentNode = fieldStart;
while (currentNode != fieldStart.GetField().End)
currentNode = currentNode.NextPreOrder(fieldStart.Document);
if (currentNode.NodeType == NodeType.FieldStart)
((FieldStart)currentNode).GetField().Result = "";
if (currentNode.NodeType == NodeType.Run)
