c# – SyntaxWalker不访问琐事

使用简单的语法walker我想访问trivias(确切地说是EndOfLineTrivia)

public sealed class MyWalker : SyntaxWalker
    {
        public int Lines { get; set; }

        public int Trivia { get; set; }

        public int Node { get; set; }

        public override void Visit(SyntaxNode node)
        {
            Node++;
            base.Visit(node);
        }

        protected override void VisitTrivia(SyntaxTrivia trivia)
        {
            Trivia++;
            base.VisitTrivia(trivia);
        }
    }

我这样叫沃克：

SyntaxTree node = CSharpSyntaxTree.ParseText(sourceCode);
    var root = node.GetRoot();
    var walker = new LocWalker();

问题

永远不会调用重写的VisitTrivia方法.
