问题描述
限时送ChatGPT账号..
我有一个像下面这样的 json:
I have a json like the following:
{
"d": {
"results": [
{
"__metadata": {
},
"prop1": "value1",
"prop2": "value2",
"__some": "value"
},
{
"__metadata": {
},
"prop3": "value1",
"prop4": "value2",
"__some": "value"
},
]
}
}
我只想将此 JSON 转换为不同的 JSON.我想从 JSON 中去掉_metadata"和_some"节点.我正在使用 JSON.NET.
I just want to transform this JSON into a different JSON. I want to strip out the "_metadata" and "_some" nodes from the JSON. I'm using JSON.NET.
推荐答案
我刚刚反序列化为 JObject 并递归地循环遍历它以删除不需要的字段.感兴趣的朋友可以看看这里的功能.
I just ended up deserializing to JObject and recursively looping through that to remove unwanted fields. Here's the function for those interested.
private void removeFields(JToken token, string[] fields)
{
JContainer container = token as JContainer;
if (container == null) return;
List<JToken> removeList = new List<JToken>();
foreach (JToken el in container.Children())
{
JProperty p = el as JProperty;
if (p != null && fields.Contains(p.Name))
{
removeList.Add(el);
}
removeFields(el, fields);
}
foreach (JToken el in removeList)
{
el.Remove();
}
}
