将DirectoryServices SearchResult序列化为JSON

Question

我无法在C＃中使用Newtonsoft将DirectoryServices SearchResult序列化为JSON。

我希望做这样的事情：

string serialized = JsonConvert.SerializeObject(searchResult.Properties);

期待收到：

{
  "cn": "Some User",
  "accountexpires": 0,
  "msexchuseraccountcontrol": 0,
  "badpasswordtime": 131710299813433259,
  "someTrueArray": [1, 2, 3]
}

相反，我得到了这个（用字符串和整数创建数组）：

{
  "cn": ["Some User"],
  "accountexpires": [0],
  "msexchuseraccountcontrol": [0],
  "badpasswordtime": [131710299813433259],
  "someTrueArray": [1, 2, 3]
}
