Once you parse your json into a JObject, the employees property will be a JArray. The JArrayclass has methods you're looking for, such as JArray.RemoveAt
将 json 解析为 a 后JObject，员工属性将是 a JArray。该JArray班有你要找的方法，如JArray.RemoveAt
The following code will do what you want
以下代码将执行您想要的操作
string json =
@"{
""employees"":[
{ ""firstName"":""John"", ""lastName"":""Doe""},
{ ""firstName"":""Anna"", ""lastName"":""Smith""},
{ ""firstName"":""Peter"", ""lastName"":""Jones""}
]
}";
dynamic obj = JObject.Parse(json);
(obj.employees as JArray).RemoveAt(0);
// obj now only has "Anna Smith" and "Peter Jones"
dynamicwas introduced in .NET 4.0, so for 3.5 you'd use something like this instead
dynamic是在 .NET 4.0 中引入的，因此对于 3.5，您可以使用类似这样的东西
JObject obj = JObject.Parse(json);
(obj["employees"] as JArray).RemoveAt(0);
