如何将C#/.NET 将json字符串格式数据转换成对象？

首先你要按JSON的结构定义一个类，类中的变量要用属性的形式.

也就是public String XX{get;set;}这样.

然后可以参考我下面的代码，是在.NET 4.6下面写的，好像3.5和4.0要用另一个类.

}


public static String Serialize<T>(T t) where T : class

{

DataContractJsonSerializer dataContractJsonSerializer = new 

DataContractJsonSerializer(typeof(T));

MemoryStream memoryStream = new MemoryStream();

dataContractJsonSerializer.WriteObject(memoryStream, t);

return Encoding.UTF8.GetString(memoryStream.ToArray(), 0, 

Convert.ToInt32(memoryStream.Length));

}

}

}
