[英]Add name value pairs to a JObject within a JArray
{
"x": null,
"y": null,
"z": null,
"things": [
{
"x": 1,
"y": 1
},
{
"x": 1,
"y": 6
}
]
}
I want to push another pair into things[0]
so that it reads 我想将另一对放入things[0]
以便读取
"things": [
{
"x": 1,
"y": 1,
"z": 9000
},
I can easily modify the values like this: 我可以轻松地修改如下值:
JObject myobject = JObject.Parse(responseString);
JArray myarray = (JArray)myobject["things"];
myarray[0]["x"] = 9000;
I can't figure out how to add/append to this object instead. 我不知道如何添加/附加到该对象。 It appears myarray[0]
is a JToken
, even though it is an object when I do GetType()
.. 看起来myarray[0]
是一个JToken
,即使我执行GetType()
时它也是一个对象。
Cast the array item to a JObject
, then use the Add
method to add a new JProperty
. 将数组项转换为JObject
,然后使用Add
方法添加新的JProperty
。 Like so: 像这样:
JObject myobject = JObject.Parse(responseString);
JArray myarray = (JArray)myobject["things"];
JObject item = (JObject)myarray[0];
item.Add(new JProperty("z", 9000));
Console.WriteLine(myobject.ToString());
