如何在 XML 文档中引用 C# 关键字？

Question

例如，<see cref="switch" /> 不起作用 - 我收到编译警告：XML comment on ... has syntactically incorrect cref attribute 'switch'

可以在SerializeProperty 的<remarks> 标记中找到相关标记。我在冗长的文档方面犯了错误。我还计划提供一些<example>s，我只是还没有开始。

cref 是指另一个成员——类、方法等。

在这种情况下，您希望它链接到什么？一般来说，您希望整体效果如何？

根据这个excellent XML doc guide，<see>标签有一个未记录的属性langword：

<see langword="switch" />

这对你有帮助吗？可能值得尝试一下，看看它能做什么。

如果您只想使用普通的超链接，请使用 href 而不是 cref：

<see href="http://msdn.microsoft.com/en-us/library/06tc147t.aspx">switch</see>
