};如阿里巴巴返回了如上的一段字符串JSON，上面是我对这个字符串进行格式化的结果
那我用什么方法可以最简单的转化为C#可访问形式的对像呢？如
result.toReturn[0].sellerAlipayId 得到 2088302179419572万分感谢
{
public myResultType result;
}public class myResultType
{
public int total;
public bool success;
public myReturnType[] toReturn;
}
public class myReturnType
{
public string sellerAlipayId;
.........
}其中 ..... 部分与其它部分一样，都是根据你的理解来定义属性和子类型。如果不定义，那么也无妨，只不过是解析时忽略掉那个属性而已。一旦定义了class，那么使用一句代码就可以从字符串反序列出.net内部对象了。你可以使用.net内置的json反序化方法，或者任何第三方json处理的类库来反序列化。
var a= (JArray)result["toReturn"];
var b=(JObject)a[0];
var c=(string)b["sellerAlipayId"];
这种方式临时写一两个也没有什么麻烦的。但是如果大量地需要这样去查找，那么可读性就差很多。既然你需要小心地编写这种一层层去查找的代码，不如干净利落地定义class，然后就放心地去直接写
result.toReturn[0].sellerAlipayId
这就得到结果了。因此要问“到底是先定义class模型的方法更简单，还是仅仅离散地分层查找属性更简单？”的问题，还是很需要自己权衡。其实两种方式都很简单。有些人认为越是访问低级的接口越简单，有些人认为越是封装好直接访问的高级的金额口越简单，每个人的出发点不同。

}ps:这个插件已经出来有段时间了，只是以前是bete版，选择性粘贴不支撑非e文区字符集设定，你用的时候需要去在“区域和语言”里换到e文区，这个比较麻烦，所以我们没有推荐使用，不过最近这个插件刚刚升级成正式版，所以已经可以正常使用了，我可以推荐大家装一下这东西一个简单介绍：http://www.infoq.com/cn/news/2013/02/asp-net-web-tools-2012-2
