【问题描述】：
我搜索了很多主题，也找到了一些相关的答案，但我仍然无法找到解决方案，因此我发布了这个问题。
问题描述
EmployeeResponse1 = [{"Ques":"1","Rating":"7"},{"Ques":"2","Rating":"1"},{"Ques":"3","Rating":"6"},{"Ques":"4","Rating":"1"},{"Ques":"5","Rating":"1"},{"Ques":"6","Rating":"1"},{"Ques":"7","Rating":"7"},{"Ques":"8","Rating":"1"},{"Ques":"9","Rating":"1"},{"Ques":"10","Rating":"1"},{"Ques":"11","Rating":"1"},{"Ques":"12","Rating":"1"},{"Ques":"13","Rating":"1"},{"Ques":"14","Rating":"1"},{"Ques":"15","Rating":"1"},{"Ques":"16","Rating":"10"}]
EmployeeResponse2 = [{"Ques":"1","Rating":"5"},{"Ques":"2","Rating":"4"},{"Ques":"3","Rating":"7"},{"Ques":"4","Rating":"8"},{"Ques":"5","Rating":"5"},{"Ques":"6","Rating":"9"},{"Ques":"7","Rating":"10"},{"Ques":"8","Rating":"4"},{"Ques":"9","Rating":"9"},{"Ques":"10","Rating":"6"},{"Ques":"11","Rating":"6"},{"Ques":"12","Rating":"6"},{"Ques":"13","Rating":"7"},{"Ques":"14","Rating":"7"},{"Ques":"15","Rating":"9"},{"Ques":"16","Rating":"8"}]
我在 c# 中有这两个 JSON 字符串（可以有更多）。现在我想制作一个最终的 JSON 字符串，如下所示：
EmployeeResponseAvg = [{"Ques":"1","Rating":"6"},{"Ques":"2","Rating":"2.5"},{"Ques":"3","Rating":"6.5"},{"Ques":"4","Rating":"4.5"},{"Ques":"5","Rating":"3"},{"Ques":"6","Rating":"5"},{"Ques":"7","Rating":"8.5"},{"Ques":"8","Rating":"2.5"},....,{"Ques":"16", "Rating": "9"}]
就像我希望 Ques = 1 的评分应该是评分（Ques = 字符串 1 的 1）和评分（Ques = 字符串 2 的 1）的平均值......对于其他问题类似
例如 FINAL =[{ QUES = 1, RATING = (Emp1(Rating.WHERE(QUES = 1), Emp2(Rating.WHERE(QUES = 1),).AVERAGE),....... .............}]
工作至今
模型 -> SurveyResponse.cs
public class SurveyResponse
{
public string Ques { get; set; }
public string Rating { get; set; }
}
public class ResponseDataCalls
{
public static SurveyResponse PutData(string t, string v)
{
SurveyResponse s = new SurveyResponse();
s.Ques = t;
s.Rating = v;
return s;
}
}
WebAPI RevGroupChartController.cs
public class RevGroupChartController : ApiController
{
private hr_toolEntities _db = new hr_toolEntities();
public object Get(int cid, int gid)
{
spiderChart obj = new spiderChart();
var group_employees = (from ge in _db.hrt_group_employee
where ge.fk_group_id == gid
select ge.fk_employee_id).ToList();
List<string> EMP = new List<string>();
List<string> SUP = new List<string>();
List<SurveyResponse> EmpResponse = new List<SurveyResponse>();
List<SurveyResponse> SupResponse = new List<SurveyResponse>();
List<List<SurveyResponse>> tmpEMP = new List<List<SurveyResponse>>();
List<List<SurveyResponse>> tmpSUP = new List<List<SurveyResponse>>();
foreach(var emp in group_employees)
{
int eid = Convert.ToInt32(emp);
var Data = (from d in _db.hrt_cycle_response
join g in _db.hrt_cycle_groups on d.hrt_cycle.pk_cycle_id equals g.fk_cycle_id
where d.fk_cycle_id == cid && g.fk_group_id == gid && d.fk_employee_id == eid
select new
{
d.response_employee_answers,
d.response_supervisor_answers
}).First();
EMP.Add(Data.response_employee_answers);
SUP.Add(Data.response_supervisor_answers);
}
foreach(var e in EMP)
{
//tmpEMP = new JavaScriptSerializer().Deserialize<TEMP>(e);
var s = new JavaScriptSerializer();
List<SurveyResponse> em = s.Deserialize<List<SurveyResponse>>(e);
tmpEMP.Add(em);
}
foreach (var s in SUP)
{
//tmpSUP = new JavaScriptSerializer().Deserialize<TEMP>(s);
var e = new JavaScriptSerializer();
List<SurveyResponse> sp = e.Deserialize<List<SurveyResponse>>(s);
tmpSUP.Add(sp);
}
var empl = _db.hrt_questions.Select(x => new { x.question_name }).ToList();
List<int[]> Emprating = new List<int[]>();
//int avgRating;
int cnt = 0;
foreach(var item in tmpSUP)
{
int noofQ = item.Count;
int[] i = new int[noofQ];
for (int y = 0; y > tmpSUP.Count; y++)
{
i[y] = Convert.ToInt32(item[cnt].Rating);
}
Emprating.Add(i);
cnt++;
}
//obj.Employee = Data.response_employee_answers;
//obj.Supervisor = Data.response_supervisor_answers;
obj.ques = new List<object>();
for (int i = 0; i < empl.Count; i++)
{
obj.ques.Add(empl[i].question_name);
}
return obj;
}
public class TEMP
{
public List<SurveyResponse> data { get; set; }
}
}
代码说明
我传递了一个循环 ID 和一个组 ID... 每组有1名以上员工，每名员工有1名主管 所以如果说组 ID 1023 有 2 名员工。 现在我们有2名员工和2名主管 我们每个人都有一个 json 记录
LIKE DB TABLE RESPONSE {fk_emp_id, fk_sup_id, cycle_id, emp_reponse(json), supervisor_response(json)}
所以我需要为员工创建一个 JSON 字符串（其中包含所有评分的平均值） 和一个用于 SUPERVISOR 的 JSON 字符串（同样，两个 JSON 的平均值） 可以有任意数量的员工，具体取决于团队规模 每个员工都会有一个主管
简而言之，我想要一个像这样的字符串：
FinalEmployeeResponse = [{'Ques': '1', 'Rating': 'R1'}, {'Ques': '2', 'Rating': 'R2'}, {'Ques': '3', 'Rating': 'R3'}, {'Ques': '4', 'Rating': 'R4'}, ........, {'Ques': '16', 'Rating': 'R16'}]
这里，R1 = AVERAGE(Emp1json.Rating.WHERE('Ques' = 1), Emp2json.Rating.WHERE('Ques' = 1), .....)
和
R2 = AVERAGE(Emp1json.Rating.WHERE('Ques' = 2), Emp2json.Rating.WHERE('Ques' = 2), .....)
……等等……
期待您的回复。
我是堆栈溢出的新手，如果我遗漏了什么，请询问更多详细信息。

如果有其他更简单的方法也可以。
