foreach (var line in tokens.Where(t => t.HasLeadingTrivia).SelectMany(t => t.GetLeadingTrivia().SplitLines()).SkipWhile(n => !n.Contains(comment)))
{
//skip outside of declaration.
if (line[0].SpanStart < node.SpanStart || line[0].SpanStart > node.Span.End) continue;
// find line contains SingleLineComment only.
foreach (var firstTrivia in line.SkipWhile(n => n.Kind() == SyntaxKind.WhitespaceTrivia).Take(1))
