具有三元表达式的C#Linq滤波器数据

我试图在

where子句中使用
Linq
，通过
startDate
和
endDate
使用
三元表达式
来过滤一些数据，但我似乎无法获得正确的逻辑

我正在使用搜索模型：

public ForecastSearchModel ForecastSearchModel { get; set; }
public class ForecastSearchModel
    {
        public ForecastSearchModel()
        {
            StartDate = DateTime.Parse("01/01/2007");
            EndDate = DateTime.Now.AddYears(3);
            Fed = DateTime.Now.AddYears(3);
        }

        public int? ProjectId { get; set; }

        public string Companies { get; set; }

        public string Clients { get; set; }

        public DateTime StartDate { get; set; }

        public DateTime EndDate { get; set; }

        public DateTime Fed { get; set; }

        public string Consultants { get; set; }

        public string Managers { get; set; }

        public string RateTypes { get; set; }

        public double? Rate { get; set; }
    }

我试图筛选的
对象是：

public IEnumerable<Dictionary<Project, IEnumerable<ProjectExtension>>> LightForecastData { get; set; }

startDate
和
EndDate
是
ProjectExtension
的属性，我试图做的是仅对具有与项目关联的
ProjectExtensions
的
词典应用过滤器

在我当前的代码中，我只得到具有ProjectExtensions（值）的项目（键），我希望保留没有任何ProjectExtensions的项目

我试过使用：

this.LightForecastData = this.LightForecastData.Where(x => x.Values.Any() ? x.Values.Any(y => y.Any(z => z.StartDate >= ForecastSearchModel.StartDate)) : true).ToList();

，我的逻辑是：


如果有任何值，请过滤我的日期
否则什么都不要做

，但它返回相同的结果

谢谢你的帮助
