c# - 删除 JArray 的成员

Question

我有以下 JSON

[
    {
        "Code": "Global Payroll",
        "Month1": 1,
        "Month2": 0,
        "Month3": 0,
        "Month4": null,
        "Month5": null,
        "Month6": null,
        "Month7": null,
        "Month8": null,
        "Month9": null,
        "Month10": null,
        "Month11": null,
        "Month12": null,
        "YTD": 1,
        "PercentOfTotal": "16.67%"
    },
    {
        "Code": "GV Payroll",
        "Month1": 0,
        "Month2": 0,
        "Month3": 3,
        "Month4": null,
        "Month5": null,
        "Month6": null,
        "Month7": null,
        "Month8": null,
        "Month9": null,
        "Month10": null,
        "Month11": null,
        "Month12": null,
        "YTD": 3,
        "PercentOfTotal": "50.00%"
    }  
]

我想要做的是以某种方式从 JSON 中删除 Month4、Month5 等，然后将其转换回字符串。

我尝试查看 JArray.remove 方法，但这会从数组中删除项目本身。有人可以告诉我如何从 JArray 中完全删除属性吗？

Answer 1

var array = JArray.Parse(json);

foreach (JObject elem in array)
{
   foreach (var elementToRemove in new List<string>() {"Month4", "Month5" })
   {
       elem.Property(elementToRemove).Remove();
    }              
}

var resultJson = array.ToString();
