在SelectToList中动态设置字典键

Question

我试图弄清楚如何动态创建一个具有未知数量密钥的字典。

model = new RecruiterMetricsViewModel() {
RecruiterMetrics = recMetrics,
    TableData = recMetrics.SelectToListOrEmpty(r => {
        return new TableRowViewModel {
            Id = r.Recruit.Id,
                Class = "",
                Data = new Dictionary < string, string > {
                    {
                        "Name", r.Recruit.FirstName + r.Recruit.LastName
                    },
      /* Here i would like to start a foreach if i could. Making the key 
         equal to an item in my object. And making the value a different 
         item in my object */
                },
        };
    })
};

型号：

public class RecruiterMetricsViewModel : ListPageViewModel
    {
        public List<RecruiterMetricsModel> RecruiterMetrics { get; set; } 
    }

    public class RecruiterMetricsModel
    {
        public RecruiterRecruitingPerformance Recruit { get; set; }

        public RecruitingPerformance DailyMetrics { get; set; }
    }

我想让密钥等于DailMetrics.Date，值等于DailMetrics.Average。
