如何在中定义自定义关键字类别listings？

在下面的 C# 列表中，关键字（例如using、namespace等）会根据需要突出显示。但是，我想定义一个名为“属性”的自定义关键字类，这样我就可以将、等声明Test为Assert属性，并以自定义样式（例如青色）突出显示它们。我该怎么做？

该listings包有一个内部宏，\lst@InstallKeywords其目的正是定义自定义关键字类。在您的例子中，调用

\lst@InstallKeywords k{attributes}{attributestyle}\slshape{attributestyle}{}ld

创建四个键：attributes、moreattributes、deleteattributes和attributestyle（默认设置为\slshape）。所有四个键均具有几乎与其等效物的用法相同keywords；唯一的区别是它们不接受任何可选参数，这意味着它们只允许一类“属性”关键字。

但是，如果需要，你可以定义一个整体家庭“属性”关键字（其中可以有多个“属性”关键字类）与另一个名为 的内部宏\lst@InstallFamily；后者的语法与 完全相同\lst@InstallKeywords。有关更多详细信息，请参阅手册。
