我正在研究ASP.NET MVC4解决方案。
I work on an ASP.NET MVC4 solution.
我有一个带有搜索条件的页面，如下所示：
I have a page with search criteria, something like this:
- 运输编号：_ _ _ __
- 运输编号至：_ _ _ _ _ _
现在我想查询该范围的模型。
Now I would like to query my model for that range.
[DataContract] public class SearchParametersTransportDTO { [DataMember] public string TransportNumberFrom { get; set; } [DataMember] public string TransportNumberTo { get; set; } } public SearchResultDTO<Transport> SearchTransports(SearchParametersTransportDTO dto) { using (var unitOfWork = UnitOfWorkFactory.Create()) { var transportRepository = unitOfWork.Create<Transport>(); var transports = transportRepository.GetAll(); transports = transports.Where(s => s.TransportNumber.Contains(dto.TransportNumberFrom)); ... } ...我不
请注意，我的运输号码不是整数，而是字符串（例如：'AZE .12 / 0009'，'AZE.12 / 0010'...）
Please note that my transport number is not an int but a string (eg: 'AZE.12/0009', 'AZE.12/0010', ...)
有什么想法吗？
谢谢。
推荐答案一个相关的问题有以下答案：运算符之间的LINQ

对于您想要的内容来说，它可能会过高，但是查询的表达式肯定是不错的
It might be overkill for what you want, but the expression of the query surely is nice an clean.
var query = transports.Between( t => t.TransportNumber, TransportNumberFrom, TransportNumberTo);
