C# 删除JSON中的空值并更新JSON

通过使用Newtonsoft序列化列表，我将JSON数组作为字符串，如下所示

[{"ID":"1","Name":"somename","Class":"12","Section":null},{"ID":null,"Name":"somename","Class":"13","Section":null},{"ID":2,"Name":"somename","Class":null,"Section":"A"}]

我需要通过将

NULL

值删除为另一个JSON字符串来转换此JSON，如下所示

[{"ID":"1","Name":"somename","Class":"12",},{"Name":"somename","Class":"13",},{"ID":2,"Name":"somename","Section":"A"}]

是否有一种方法可以使用Newtonsoft进行此操作，或者如何进行此操作

您可以将

JsonSerializerSettings

与

NullValueHandling

一起使用：

var result = JsonConvert.SerializeObject(obj, 
            new JsonSerializerSettings() 
            { 
                NullValueHandling = NullValueHandling.Ignore 
            });
