我正在尝试执行嵌套的linq查询。
public class Sic
{
public int Id { get; set; }
public string Code { get; set; }
}
public class Message
{
public List<Sic> Sics { get; set; }
public int Id { get; set; }
}
List<Message> msgList = new List<Message>();
Message m1 = new Message
{
Id = 0,
Sics = new List<Sic>()
{
new Sic() {Id = 0, Code = "A2A"},
new Sic() {Id = 1, Code = "A2B"},
new Sic() {Id = 2, Code = "A2C"},
new Sic() {Id = 3, Code = "A2D"}
}
};
Message m2 = new Message
{
Id = 1,
Sics = new List<Sic>()
{
new Sic() {Id = 4, Code = "B2A"},
new Sic() {Id = 5, Code = "B2B"},
new Sic() {Id = 6, Code = "B2C"},
new Sic() {Id = 7, Code = "B2D"}
}
};
msgList.Add(m1);
msgList.Add(m2);
List<string> searchList = new List<string> {"A2A", "A2B"};
我想在msgList中找到消息,其中每个消息的Sics包含searchList,即应使用上面的searchList找到m1。

你可以使用类似的东西,
msgList.Where(msg=>msg.Sics.Any(sic=>searchList.Contains(sic.Code)));
或者如果您需要匹配所有搜索字词,
msgList.Where(msg => searchList.All(searchTerm=>msg.Sics.Any(sic=>sic.Code==searchTerm)))

如果搜索列表中的所有ID都需要匹配
msgList.Where(msg => searchList.Any() && searchList.All(s => msg.Sics.Any(sic => s==sic.Code)))
如果搜索列表中的任何ID需要匹配
msgList.Where(msg=>msg.Sics.Any(sic=>searchList.Contains(sic.Code)));
