@Princeshivananjappa,

Here is a sample code to check if it has TOC fields or not.

// check if there are ToC fields
var tocFields = doc.Range.Fields.Where(f => f.Type == FieldType.FieldTOC);

if (tocFields.Any())
    Console.WriteLine("Has ToC elements");
else
    Console.WriteLine("Does not has ToC elements");
