遵循Ruby屬性命名約定的C＃JSON.NET約定？

Question

我正在使用http://json.codeplex.com/，我正在與基於Ruby的Rest API進行通信。問題是，大多數屬性都有一個紅寶石下劃線的命名約定。我想知道如果有人知道一種方式，以便我可以避免必須添加大量的JsonProperty。

比如我想避免添加JsonProperty屬性，並公約內置串行化器設置，以便它知道在用下劃線嘗試和地圖屬性的.NET命名約定:)

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 SnakeCaseNamingStrategy。您可以使用它自動擁有twitter_screen_name樣式屬性。

繼承DefaultContractResolver並覆蓋ResolvePropertyName格式化屬性名稱，只要你願意。

CamelCasePropertyNamesContractResolver對屬性名稱做了類似的全局更改。

閱讀：http://nyqui.st/json-net-newtonsoft-json-lowercase-keys

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(); 
     } 
    } 

Answer 3

這一個爲我工作

var settings = new JsonSerializerSettings 
{ 
    ContractResolver = new PascalCaseToUnderscoreContractResolver() 
}; 
var rawJson = "{ test_property:'test' }" 
var myObject = JsonConvert.DeserializeObject<MyObjectType>(rawJson, settings); 

使用Humanizer功能 「下劃線」

https://www.nuget.org/packages/Humanizer/1.37.7

http://humanizr.net/#underscore

public class PascalCaseToUnderscoreContractResolver : DefaultContractResolver 
{ 
    protected override string ResolvePropertyName(string propertyName) => propertyName.Underscore(); 
} 

MyObjectType類

public Class MyObjectType 
{ 
    public string TestProperty {get;set;} 
} 

Answer 4

截至9版本，新的命名策略屬性存在，要做到這一點，它有一個內置的SnakeCaseNamingStrategy類。使用以下代碼並將contractResolver註冊爲SerializerSettings.ContractResolver。

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

該類默認不包含字典，並且不會覆蓋任何手動設置的屬性值。這些是可以通過過載的兩個參數：

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