c# - 如何将两个 Entity Framework 调用合并为一个？

Question

所以我有以下代码:

    var MAX_VOLUME = (from b in context.TRANSPORT_PLANNER_TRACK_CAP.Where(b => b.WAREHOUSE.Equals(warehouse)) select b.MAX_VOLUME).SingleOrDefault();
    var MAX_WEIGHT = (from b in context.TRANSPORT_PLANNER_TRACK_CAP.Where(b => b.WAREHOUSE.Equals(warehouse)) select b.MAX_WEIGHT).SingleOrDefault();
string maxVolume = MAX_VOLUME.ToString();
string maxWeight = MAX_WEIGHT.ToString();

我想将这两个语句合并到一个 EF 调用中，以减少冗余。最好的方法是什么？

Answer 1

var result = (from b in context.TRANSPORT_PLANNER_TRACK_CAP
              where b.WAREHOUSE.Equals(warehouse)
              select new { b.MAX_VOLUME, b.MAX_WEIGHT}).SingleOrDefault();

然后将其引用为:

result.MAX_WEIGHT or result.MAX_VOLUME
