问题中的示例是一个更简单的情况，其中属性名称在json和代码中完全匹配。如果属性名称不完全匹配，例如json中的属性为 "first_name": "Mark" ，而代码中的属性为 FirstName ，则使用 Select method ，如下所示

List<SelectableEnumItem> items = ((JArray)array).Select(x => new SelectableEnumItem
    FirstName = (string)x["first_name"],
    Selected = (bool)x["selected"]
}).ToList();

在我的例子中，API返回值如下：

{
  "pageIndex": 1,
  "pageSize": 10,
  "totalCount": 1,
  "totalPageCount": 1,
  "items": [
      "firstName": "Stephen",
      "otherNames": "Ebichondo",
      "phoneNumber": "+254721250736",
      "gender": 0,
      "clientStatus": 0,
      "dateOfBirth": "1979-08-16T00:00:00",
      "nationalID": "21734397",
      "emailAddress": "sebichondo@gmail.com",
      "id": 1,
      "addedDate": "2018-02-02T00:00:00",
      "modifiedDate": "2018-02-02T00:00:00"
  "hasPreviousPage": false,
  "hasNextPage": false
}

将items数组转换为客户端列表的过程如下所示：

 if (responseMessage.IsSuccessStatusCode)
            var responseData = responseMessage.Content.ReadAsStringAsync().Result;
