}这是我从应用程序获得的JSON响应，还有许多其他API get返回相同类型的响应(嵌套)，因此这必须动态完成，因为用户正在从配置文件添加API调用，所以我不能使用get和set创建预制的类。我的目标是将这些数据转换为数据表，以便在看到嵌套列时插入到数据库中，我的目标是使用"_“ex: category_id = "”或integrations_xero_basecurrency = "“等附加父列名称。
这是我用来将数据制表的代码，但在代码中，只有当列是JValue (键和值)时，它才会获取列，并且我无法创建一个合适的循环来完成此任务。
public DataTable Tabulate(string jsonContent)
{
var jsonLinq = JObject.Parse(jsonContent);
// Find the first array using Linq
var srcArray = jsonLinq.Descendants().Where(d => d is JArray).First();
//Console.WriteLine("extarcted data:" + srcArray);
var trgArray = new JArray();
foreach (JObject row in srcArray.Children<JObject>())
{
var cleanRow = new JObject();
foreach (JProperty column in row.Properties())
{
// Only include JValue types
if (column.Value is JValue)
{
cleanRow.Add(column.Name, column.Value);
}
}
trgArray.Add(cleanRow);
}
DataTable dt = JsonConvert.DeserializeObject<DataTable>(trgArray.ToString());
return dt;

这样如何：
public DataTable Tabulate(string jsonContent)
{
var jsonLinq = JObject.Parse(jsonContent);
// Find the first array using Linq
var arrayProp = jsonLinq.Properties().First(p => p.Value is JArray);
var srcArray = (JArray)arrayProp.Value;
// Set up a regex consisting of the array property name and subscript
// (e.g. "projects[0]."), which we will strip off
var regex = new Regex($@"^{arrayProp.Name}\[\d+\]\.");
// Flatten each object of the original array
// into new objects and put them in a new array
var trgArray = new JArray(
srcArray.Children<JObject>()
.Select(row => new JObject(
row.Descendants()
.OfType<JProperty>()
.Where(p => p.Value is JValue)
.Select(p => new JProperty(
regex.Replace(p.Value.Path, "").Replace(".", "_"),
p.Value
))
))
);
// Convert the new array to a DataTable
DataTable dt = trgArray.ToObject<DataTable>();
return dt;
