C# 复杂 Json 反序列化

Question

我正在尝试反序列化此 json 但这很复杂 json 而我做不到。实际上，我试图在 http://json2csharp.com/ 中创建一个 class，但它再次不起作用。你能帮我弄清楚吗

    {

    "?xml":{

    "@version":"1.0",

    "@encoding":"utf-8"

    },

    "ArrayOfPerson":{

    "@xmlns:xsd":"http://www.w3.org/2001/XMLSchema",

    "@xmlns:xsi":"http://www.w3.org/2001/XMLSchema-instance",

    "alert":[

    {

    "@xmlns":"urn:url:taces:numarates",

    }

    }

    ... array items

    }
    }

您的问题似乎是因为您的 JSON 属性名称不能用作 C# 变量 "as is" 因此 json2charp returns 名称如 "invalid-name__@version"

几乎所有 Json 反序列化器，包括 DataContractJsonSerializers 和 Json.Net 都可以支持自定义数据成员名称。它不需要与 class 中的属性名称相同。参考DataMember attribute on MSDN

或者，您可以使用 Json.Net 库和 JsonReader 按名称手动寻址属性 http://insidethecpu.com/2013/06/19/json-parsing/
