C# 轻松处理json对象
我正在将json字符串反序列化（或解析）为c#对象（使用json.NET）并获得一个JObject。我想用键“bla”迭代所有属性，就像用XElement.elements（“bla”）迭代所有名为“bla”的xml元素一样 如果不可能，我希望将我的json字符串反序列化为一个c#对象，并在反序列化的json对象上动态递归地工作（我的json字符串可以有两种类型的对象的列表/数组）。 最后，在编辑对象（更改值、删除或添加属性）后，我需要将对象序列化回json字符串。 使用json序列化和反序列化的最佳和最简单的方法是什么 我的Json如下所示：C# 轻松处理json对象,c#,json,xml,object,serialization,C#,Json,Xml,Object,Serialization,我正在将json字符串反序列化（或解析）为c#对象（使用json.NET）并获得一个JObject。我想用键“bla”迭代所有属性，就像用XElement.elements（“bla”）迭代所有名为“bla”的xml元素一样 如果不可能，我希望将我的json字符串反序列化为一个c#对象，并在反序列化的json对象上动态递归地工作（我的json字符串可以有两种类型的对象的列表/数组）。 最后，在编辑对象（更改值、删除或添加属性）后，我需要将对象序列化回json字符串。 使用json序列化和反序列化

总之，json值是一个json对象，它的值是一个列表/数组，列表/数组可以包含2个“类型”其中一种类型也有一个属性，它的值是一个json对象，它的值是一个列表/数组，它是这样递归的。有时候，这个类型的一个道具的值没有一个属性，它的值是一个json对象，它的值是一个列表/数组，它的值可以是一个列表/数组本身，它可以包含n上述两种类型中只有一种。如果不需要强类型对象，可以反序列化到字典：
Dictionary<string, object> myObject = JsonConvert.DeserializeObject<Dictionary<string, object>>(jsonString);
myObject["Property"] = value;
