Question

我继承了一些LINQ，我想把它重写为非LINQ C＃，这样我就可以解决哪个位失败了。

（我订购了ReSharper，但JetBrains的许可证密钥似乎很慢。）

LINQ是

var accounts = from a in srvContext.CreateQuery<Incident>()
                join b in srvContext.CreateQuery<integ_benefitallowances>() on a.integ_BenefitId.Id equals b.integ_benefitallowancesId.Value
                where b.integ_BenefitId.Id == _currentIncident.integ_BenefitId.Id
                where a.Integ_DependantId.Id == a.Integ_DependantId.Id
                where a.integ_ClaimStatus.Value == 0 || a.integ_ClaimStatus.Value == 2
                where a.Integ_DateofClaim.Value > timePeriod
                select new Incident
                {
                     LogicalName = a.LogicalName
                };

错误是

System.ServiceModel.FaultException`1[[Microsoft.Xrm.Sdk.OrganizationServiceFault, Microsoft.Xrm.Sdk, Version=5.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35]]: There was an error with this process
variable '<>h__TransparentIdentifier2' of type '<>f__AnonymousType0`2[PaycareCRM.Incident,PaycareCRM.integ_benefitallowances]' referenced from scope '', but it is not defined

是否有网站或简单的工具可以将LINQ转换为普通的C＃？

XY问题。

DataServiceContext does not support Join or Select (except as the identity operator).

ReSharper揭示了这个问题 - 一条线是重言式（并且RS下划线强调了它），虽然我不明白为什么这意味着查询失败了。无论如何，固定代码是

var incidents = from a in srvContext.CreateQuery<Incident>()
                join b in srvContext.CreateQuery<integ_benefitallowances>() on a.integ_BenefitId.Id equals b.integ_benefitallowancesId.Value
                where b.integ_BenefitId.Id == _currentIncident.integ_BenefitId.Id
                where a.Integ_DependantId.Id == _currentIncident.Integ_DependantId.Id
                where a.integ_ClaimStatus.Value == 0 || a.integ_ClaimStatus.Value == 2
                where a.Integ_DateofClaim.Value > timePeriod
                select new Incident
                        {
                                LogicalName = a.LogicalName
                        };

解码LINQ的服务？
