在JSON和JSON更新删除Null值 [英] Remove Null values in JSON and Update JSON

问题描述

我JSON阵列作为一个字符串通过采用序列Newtonsoft如下

I have JSON Array as a string by serializing a list using Newtonsoft as below

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

我需要像下面

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

有没有一种方法，我可以使用Newtonsoft这个或我怎么做到这一点。

Is there a way I can use Newtonsoft for this or how do i do this.

推荐答案

您可以使用 JsonSerializerSettings 与 NullValueHandling ：

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