我通过 Nuget 在我的项目中包含了 System.Linq.Dynamic 库。以下是我的 linq 查询,如果我使用要在选择中返回的类型字段,它可以正常工作。但是使用 System.Linq.Dynamic 我应该能够为选择使用字符串值。我遵循了我找到的示例,但我从选择中得到的只是字符串本身。我错过了什么?
var predicate = PredicateBuilder.False<Name>();
predicate = predicate.And(d => d.ID == "100053");
var results = from n in Names
.AsExpandable()
.Where(n=> n.ID=="100053")
join d in InstitutionDemographics on n.ID equals d.ID
join m in MemberAdhocIds on n.ID equals m.ID
join a in NameAddresses on n.BillingAddressNumber equals a.AddressNumber
join mas in MemberAdhocServices on n.ID equals mas.InstitutionID
select("new(n.ID,n.Company,n.MemberStatus,n.Email,n.MemberType,n.USCongress,n.FAX,n.County,d.NumberYearsAMember,d.Population,d.FederalReserveDistrict,d.FDICCertificateNumber,d.FRSID,d.ICBADistrictCode,d.UD_Minority_Type,d.MSA,d.NumberOfBranches,d.PubliclyTraded,d.SRAMemberships,d.Assets,d.RSU,d.FutureDues,d.InstitutionType,d.AgLoanPercentageTotal,m.CCRP,a.City,a.State,a.Address1,a.ZIP)");
results.Dump();
