API应该数组形式返回数据

Question

我希望我的API应该像返回数据：

"value": [{ 
    "Name": "Name1", 
    "countries": ["1st Country", "2nd Country", "3rd Country"], 
    "Address": "Address1" 
}, { 
    "Name": "Name2", 
    "countries": ["3st Country", "4nd Country", "6rd Country"], 
    "Address": "Address2" 
}] 

当我使用它列表，它返回这样的：

"countries": [ 
    { "Country": "3st Country" }, 
    { "Country": "4st Country" }, 
    { "Country": "6st Country" } 
] 

但是我要像：

"countries": ["3st Country", "4nd Country", "6rd Country"], 

能否请您分享一些样本编码来实现它

My Coding is like 

    public List<CompanyDto> GetCompanyData() 
     { 
      List<CompanyDto> resultCompanyDtoViews = new List<CompanyDto>(); 

      var viewCompanyDtoData = db.ds_CompanyDto.AsQueryable().AsNoTracking().ToList(); 

      var companyDtoData = viewCompanyDtoData .Select(a => new CompanyDto() 
      { 
       Id = a.Id, 
       CompanyId=a.CompanyId, 
       CompanyName=a.CompanyName, 
      }).GroupBy(a => a.CompanyId).Select(a => a.First()).ToList(); 

      foreach (var companyData in companyDtoData) 
      { 
       CompanyDto companyDto = new CompanyDto(); 
       companyDto.Id = companyData.Id; 
       companyDto.CompanyId=companyData.CompanyId; 
       companyDto=companyData.CompanyName 

       companyDto.countries = 
        viewCompanyDtoData.Where(a => a.CompanyId == companyData.CompanyId).Select(a => new CountryDto() 
        { 
         Country = a.Country 
        }).ToList(); 
       resultCompanyDtoViews.Add(companyDto); 
      } 


      return resultCompanyDtoViews; 
     } 

-----------------------------------Coding in DTO class 
public class CompanyDto 
    { 
     [Key] 
     public Nullable<long> Id { get; set; } 
     public int CompanyId { get; set; }   
     public string CompanyName { get; set; } 
     public List<CountryDto> countries { get; set; } 
    } 
public class CountryDto 
{ 
public string Country { get; set; } 
} 
----------------------Out put Now getting 
{ 
    "value": [ 
    { 
     "Id": 1, 
     "CompanyId": 1, 
     "CompanyName": "TCS", 
     "countries": [ 
     { 
      "Country": "3st Country" 
     }, 
     { 
      "Country": "4st Country" 
     }, 
     { 
      "Country": "6st Country" 
     } 
     ] 
    } 
    ] 
} 
--------------------------Expected Output 

{ 
    "value": [ 
    { 
     "Id": 1, 
     "CompanyId": 1, 
     "CompanyName": "TCS", 
     "countries": [ 
     "3st Country", 
     "4st Country", 
     "6st Country" 
     ] 
    } 
    ] 
}
