C#9 不支持 JsonPropertyNameAttribute 记录? [英] JsonPropertyNameAttribute is not supported record from C#9?

问题描述

我想使用带有 JsonPropertyName 属性的记录，但它导致了错误.这个不支持?有什么解决方法吗?

I want to use record with JsonPropertyName attribute, but it caused an error. This is not supported? Any workaround?

public record QuoteResponse([JsonPropertyName("quotes")] IReadOnlyCollection<Quote>? Quotes);

Error CS0592 Attribute 'JsonPropertyName' is not valid on this declaration type. It is only valid on 'property, indexer, field' declarations.

推荐答案

默认情况下，记录参数的属性适用于参数.要使它们适用于属性，您必须在它前面加上 property: 属性 location:

By default attributes on record parameters apply to the parameter. To make them apply to the property you have to prefix it with the property: attribute location:

public record QuoteResponse([property: JsonPropertyName("quotes")] IReadOnlyCollection<Quote>? Quotes);
