c# - 将两个查询合并为一个查询

Question

我有两个查询都有效，但需要将它们组合成一个有效的查询

查询 1

  var now = DateTime.Now;
  var twoWeeksAgo = now.AddDays(-14);

  var advert =
      from m in db.tbl_Property
      where m.Prop_Update >= twoWeeksAgo && m.Prop_Update <= now
      select m;

查询 2

  var Props = 
      from n in db.tbl_Property.
      Where(c => c.Prop_AvailableSpaces > 0)
      select n;

欢迎任何帮助或建议

Answer 1

我会将这些查询更改为传入原始 IQueryable<Property> (或任何类型)，然后你可以这样做:

var advert = from m in source
             where m.Prop_Update >= twoWeeksAgo && m.Prop_Update <= now
             select m;

通过 db.tbl_Property作为source ，然后:

var Props = from n in filteredProperties
            where n.Prop_AvailableSpaces > 0
            select n;

即组成
