如何在roslyn中删除语法树中的标记。 例如从属性中删除虚拟关键字令牌？

Question

How do I remove token in syntax tree in roslyn. eg remove virtual keyword token from property? Roslyn has RemoveNode method but I can't find RemoveToken method or a way to remove token.

Answer 1

Found the answer. To remove, replace the token with new token of kind none. Awkward but works.

var noneToken = SyntaxFactory.Token(SyntaxKind.None);
node = node.ReplaceToken(token_to_remove, noneToken);

Answer 2

I'm getting an ArgumentException when running the above code. This seems to work (though it may be a bit of a hack):

var node = node.ReplaceToken(dotToken_to_remove, SyntaxFactory.MissingToken(SyntaxKind.DotToken));
