推荐答案

只是@SLaks 答案的一些扩展.您需要扩展 CSharpSyntaxRewriter 并覆盖 VisitTrivia 方法.在这里，您需要检查琐事的Kind.根据您的需要，您应该过滤单行和多行注释:

Just some extensions to @SLaks' answer. You need to extend CSharpSyntaxRewriter and override the VisitTrivia method. And here you'll need to check the Kind of the trivia. Depending on your needs, you should filter for single and multiline comments:

trivia.IsKind(SyntaxKind.SingleLineCommentTrivia) || trivia.IsKind(SyntaxKind.MultiLineCommentTrivia)

并返回 default(SyntaxTrivia) 以将它们从树中删除.

And return default(SyntaxTrivia) to remove them from the tree.
