阅读更多关于 JSON.Net JsonConverter for DbGeography

问题 Long long struggles with this... Basically I have a model-first EF5 object with a DbGeography property. I would like to apply a JsonConverter that let's it roundtrip as simple latitude/longitude values. I'm using WebAPI.

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 我在JSON中有一个简单的键/值列表，该列表通过POST发送回ASP.NET。例： { "key1": "value1", "key2": "value2"} 我不打算将序列化为严格类型的.NET对象我只需要一个普通的旧 Dictionary（Of String，String）或某些等效项（哈希表，Dictionary（Of String，Object），老式的StringDictionary-地狱，二维字符串数组对我来说就可以工作。我可以使用ASP.NET 3.5以及流行的Json.NET（我已经在使用它序列化到客户端）中使用的任何东西。显然，这两个JSON库都不具有这种开箱即用的明显功能-它们完全专注于通过强合同进行基于反射的反序列化。有任何想法吗？局限性：我不想实现自己的JSON解析器尚不能使用ASP.NET 4.0 希望远离JSON不再使用的旧的ASP.NET类 #1楼十分烦人的是，如果您要使用默认的模型绑定程序，则看起来您将不得不使用数字索引值（如POST表单）。请参阅本文的以下摘录 http://msdn.microsoft.com/zh-cn/magazine/hh781022.aspx ：尽管有点违反直觉，但JSON请求具有相同的要求-它们也必须遵守表单后命名语法。

问题 I found the same question here... Deserializing nested JSON structure to a flattened class with Json.NET using annotations ...but without a proper answer. One of the best suggestion is to wrap the nested object in a new class but this approach introduces another issue: lego name. In my example the most logic name for this class is the same name that parent class and of course is not possible. My example is simple, I just want to eliminate the "language" property in the parent class. Can
