如何使用JToken从JObject中的数组中获取多个值并将其存储在列表中

Question

我有以下来自服务器的响应消息作为字符串：

string receivedResult = "{"method":"_result","params":[[{"idmake":1,"name":"Abarth","important":0,"description":{"DE":"Abarth & C.

现在，当我通过以下语句解析这个包含JSON的字符串时：

var jObject = JObject.Parse(receivedResult);

我得到以下格式化输出：

我想循环遍历paramsJArray的每个数组，获取每个name字段的值，并将这些值存储在一个列表中。

我可以通过以下代码从第一个数组Abarth中获取名称值：

JArray paramsArray = (JArray)jObject["params"];
List<string> listName = new List<string>();
foreach(JToken param in paramsArray)
{
name = (string)param[0]["name"]; // Here I got the target result name="Abarth" from index 0 of array
listName.Add(name);
foreach(var item in listName)
{
tbResultCreateNewAd.Text = item.ToString();
}

}

我想知道如何在其他数组中循环并获取名称值我曾尝试for loop，但没有成功，因为我对与Json合作完全陌生。谢谢大家

Answer 1

我已经找到了如何在花了一段时间后完成，通过while循环，我对子数组的最后一个索引号进行了硬编码，然后进行了迭代，也许对此有不同的解决方案，但目前这种逻辑对我来说是有效的，combobox是在点击事件正确触发后填充的。

以下是解决方案：

var jObject = JObject.Parse(receivedResult);
JArray paramsArray = (JArray)jObject["params"];
foreach(JToken param in paramsArray)
{
int i = 0;
while(i<614) // 614 is hardcoded number for last array index
{ 
name = param[i]["name"].ToString();
listName.Add(name);
i++;

}
break;
}
cbMake.DataSource = listName;
