C# 将linq to对象查询结果放入类型化词典

林克还是个新手。似乎应该有一种更优雅的方法来使用ToDictionary来实现这一点，但无法理解。这是我要清理的代码：

 var EventOccurrencesMappedToPatientMeds = from pm in allPtMeds
      from e in thisUsersEventOccurrencesPlusEventData
      where e.EventContainer.Event.PatientMedId == pm.MedicationId
      select new ScheduleEventOccurrenceMedPair{ 
           PatientMedication = pm, 
           ScheduledEventOccurrence = e.EventOccurrence 
      };

 int evtOccCount = 1;
 foreach (var evtOcc in EventOccurrencesMappedToPatientMeds)
 {
      // EventOccurrenceChoices is a Dictionary of type <int, IScheduledEventOccurrenceMedPair>
      message.EventOccurrenceChoices.Add(evtOccCount,(ScheduleEventOccurrenceMedPair)evtOcc);
 }

var EventOccurrencesMappedToPatientMeds=来自所有pTMED中的pm
来自此UserSeventRecurrenceSpluseventData中的e
其中e.EventContainer.Event.PatientMedId==pm.MedicationId
选择新的ScheduleEventOccurrenceMedPair{
PatientMedical=pm，
ScheduledEventOccurrence=e.EventOccurrence
};
int EVTOCCOUNT=1；
foreach（事件发生中的var evtOcc似乎是患者用药）
{
//EventOccurrenceChoices是一个类型为
message.EventOccurrenceChoices.Add（EVTOccount，（ScheduleEventoccurrencedPair）evtOcc）；
}

使用

ToDictionary

扩展方法

大概是这样的：

var i = 1;
var resultDictionary = (
    from pm in allPtMeds
    from e in thisUsersEventOccurrencesPlusEventData
    where e.EventContainer.Event.PatientMedId == pm.MedicationId
    select new ScheduleEventOccurrenceMedPair
    {
        PatientMedication = pm,
        ScheduledEventOccurrence = e.EventOccurrence
    })
    .ToDictionary(arg => i++, arg => arg);

您可以使用重载包含索引，然后使用

ToDictionary

：

var dict = EventOccurrencesMappedToPatientMeds
               .Select((e, i) => new { Event = e, Index = i + 1 })
               .ToDictionary(o => o.Index,
                             o => (ScheduleEventOccurrenceMedPair)o.Event);
