遵循Ruby属性命名约定的C#JSON.NET约定？

Question

我正在使用http://json.codeplex.com/,我正在谈论基于Ruby的Rest API.问题是大多数属性都有一个ruby下划线命名约定.我想知道是否有人知道一种方式,以便我可以避免添加大量的JsonProperty.

例如,我想避免添加JsonProperty属性并在序列化程序设置中内置一个约定,以便它知道在.NET命名约定中尝试使用下划线映射属性:)

public class Member
{
    [JsonProperty(PropertyName = "avatar_url")]
    public string AvatarUrl { get; set; }

    [JsonProperty(PropertyName = "twitter_screen_name")]
    public string TwitterScreenName { get; set; }

    [JsonProperty(PropertyName = "website_url")]
    public string WebSiteUrl { get; set; }
}

Answer 1

更新 - 2016年9月:

Json.NET 9.0.1有SnakeCaseNamingStrategy.您可以使用它自动拥有twitter_screen_name样式属性.

根据需要继承DefaultContractResolver和覆盖ResolvePropertyName格式化属性名称.

CamelCasePropertyNamesContractResolver 对属性名称进行类似的全局更改.

public class UnderscoreMappingResolver : DefaultContractResolver 
    {
        protected override string ResolvePropertyName(string propertyName)
        {
            return System.Text.RegularExpressions.Regex.Replace(
                propertyName, @"([A-Z])([A-Z][a-z])|([a-z0-9])([A-Z])", "$1$3_$2$4").ToLower(); 
        }
    }

从版本9开始,存在一个新的命名策略属性,它具有内置的SnakeCaseNamingStrategy类.使用下面的代码并注册contractResolver为SerializerSettings.ContractResolver.

var contractResolver = new DefaultContractResolver();
contractResolver.NamingStrategy = new SnakeCaseNamingStrategy();

默认情况下,该类不包括字典,并且它不会覆盖任何手动设置的属性值.这些是可以在重载中传递的两个参数:

// true parameter forces handling of dictionaries
// false prevents the serializer from changing anything manually set by an attribute
contractResolver.NamingStrategy = new SnakeCaseNamingStrategy(true, false);
