推荐答案

记住新{property =value};是创建匿名类型的语法。因此，类型中定义的属性名称仍必须遵循标识符命名规则。所以禁止使用诸如'@'，'：'，'。'之类的符号。



在标识符之前使用@并不是逃避，但是C＃语言的一个功能是允许你使用关键字作为标识符。



因此，如果你想使用高度自定义的属性名称，你唯一的选择就是传递一个IDictionary 。说到这一点，我鼓励您改为使用自定义属性的数据前缀。不仅是标准，而且HtmlHelper还有内置支持。在定义匿名类型时，只需使用下划线代替连字符，HtmlHelper将转换它们。

Remember that new { property = "value" }; is the syntax for creating an anonymous type. As such, the property names defined within the type still have to follow the identifier naming rules. So using symbols such as '@', ':', '.' is prohibited.

Using the @ before an identifier isn't so much as an escape, but a feature of the C# language that lets you use keywords as identifiers.

So if you want to use highly customized attribute names, your only option is to pass an IDictionary. With saying that, I encourage you to to instead use the data- prefix for custom attributes. Not only is that standard, but the HtmlHelper has built-in support. Simply use underscores in place of the hyphens when defining your anonymous type, and the HtmlHelper will convert them.
