使用JSON设置私有属性 [英] Using JSON to set private properties

问题描述

我正在尝试使用从Web服务获取的JSON值设置某些私有属性的值.

A)这可能吗
B)如果是，该怎么办?

让我再次重申.我需要公共财产才能拥有私人二传手.我尝试将设置器设置为内部，然后更改AssemblyInfo文件以将内部公开给Newtonsoft.Json.这也不行吗?

这是我的代码:

I am trying to set the values of some private properties with JSON values that I am getting from a web service.

A) Is this possible
B) If so, how do I do it?

Let me re-iterate. I need the public property to have a private setter. I have tried setting the setter to internal and then changing the AssemblyInfo file to expose internals to Newtonsoft.Json. This doesnt work either?

Here is my code:

using (WebClient wc = new WebClient())
{
        DataContractJsonSerializer js = new DataContractJsonSerializer(typeof(MyAmazingObject));
        return (FacebookUser)js.ReadObject(wc.OpenRead("URL_HERE"));
}

推荐答案

很遗憾，Vivek的回答不正确.

如果使用数据合约，则可以使用私有成员的序列化.您需要使用System.Runtime.Serialization.Json.DataContractJsonSerializer，请参阅 http ://msdn.microsoft.com/zh-CN/library/system.runtime.serialization.json.datacontractjsonserializer.aspx [ http://msdn.microsoft.com/en-us/library/ms733127.aspx [^ ].

使用数据协定时，元数据不仅由访问说明符定义，而且由特殊属性(例如[DataMember])定义.与常规的旧版"序列化相比，数据契约更具非侵入性，并且更具优势.

另请参阅我过去提倡数据合约方法的答案:

The answer by Vivek is unfortunately incorrect.

You can use serialization of private members if you use Data Contract. You need to use System.Runtime.Serialization.Json.DataContractJsonSerializer, see http://msdn.microsoft.com/en-us/library/system.runtime.serialization.json.datacontractjsonserializer.aspx[^].

To get the idea, read this: http://msdn.microsoft.com/en-us/library/ms733127.aspx[^].

When you use Data Contract, the meta-data is defined not just by access specifier, but by special attributes such as [DataMember]. Data Contract is much more non-intrusive and beneficial over regular "legacy" serialization.

Please see also my past answer where I advocate Data Contract approach:
