C# 用roslyn修复程序替换注释（在正确位置添加琐事）

给定以下“代码修复”
我正在尝试替换属性的文档元素，并将其替换为快速修复文档

我正在为琐事挣扎

    private Task<Document> AddDocumentationAsync(CodeFixContext context, SyntaxNode root, DocumentationCommentTriviaSyntax xmlElementSyntax)
    {
        const string comment = "THIS IS THE NEW COMMENT";
        var text =
            SyntaxFactory.XmlText(SyntaxFactory.TokenList(
                SyntaxFactory.XmlTextLiteral(
                    SyntaxFactory.TriviaList(),
                    comment,
                    comment,
                    SyntaxFactory.TriviaList())));

        var textList = SyntaxFactory.List<XmlNodeSyntax>(new[] {text});
        XmlNodeSyntax[] nodes = new XmlNodeSyntax[]
        {
            SyntaxFactory.XmlElement(
                SyntaxFactory.XmlElementStartTag(SyntaxFactory.XmlName("summary")),
                textList,
                SyntaxFactory.XmlElementEndTag(SyntaxFactory.XmlName("summary"))),
        };
        var list = SyntaxFactory.List<XmlNodeSyntax>(nodes);
        var newDocumentation = SyntaxFactory.DocumentationCommentTrivia(
            SyntaxKind.SingleLineDocumentationCommentTrivia,
            list);

        var spaced = newDocumentation.WithTriviaFrom(xmlElementSyntax);
        var n1 = root.ReplaceNode(xmlElementSyntax, spaced);

        var newDocument = context.Document.WithSyntaxRoot(n1);
        return Task.FromResult(newDocument);
    }

我的注册码是这样的

    var documentationStructure = node.GetDocumentationCommentTriviaSyntax();
    var xmlElementSyntax = documentationStructure;
    var action = CodeAction.Create("Create XML Documentation", c => this.AddDocumentationAsync(context, root, xmlElementSyntax), "Create XML Documentation");
    context.RegisterCodeFix(
        action,
        diagnostic);

您需要向注释添加

EndOfDocumentationCommentToken

标记。您可以尝试以下操作：

.WithEndOfComment（SyntaxFactory.Token（SyntaxKind.EndOfDocumentationCommentToken））

---

顺便说一句，你可以查一下作为参考

您将从方法声明行的开头开始，并在那里插入注释。您也可以插入换行符，您是否尝试过在注释结尾插入换行符？您可以通过在文档结构中查找换行符来了解如何执行此操作…我尝试了一些组合，但无法获得正确的琐事。不要手动执行所有这些操作--只需使用

.WithAdditionalAnnotations

将

格式化程序.Annotation

添加到XML中即可。当代码修复程序被执行时，它会寻找这些注释并对它们进行适当的格式化。那个在线工具，该死的，我要用它。

    var documentationStructure = node.GetDocumentationCommentTriviaSyntax();
    var xmlElementSyntax = documentationStructure;
    var action = CodeAction.Create("Create XML Documentation", c => this.AddDocumentationAsync(context, root, xmlElementSyntax), "Create XML Documentation");
    context.RegisterCodeFix(
        action,
        diagnostic);
