@Manasahr You should set FieldToc.InsertHyperlinks and FieldToc.HideInWebLayout properties to get the desired output. For example see the following code:

Document doc = new Document(@"C:\Temp\in.docx");

doc.Range.Fields.Where(f => f.Type == FieldType.FieldTOC).Cast<FieldToc>().ToList()
    .ForEach(f => { f.InsertHyperlinks = true; f.HideInWebLayout = true; f.Update(); });

doc.Save(@"C:\Temp\out.docx");
