エンティティフレームワークコア - （サブクエリの種類）

Question

私は流暢なAPIとEfコアを使用しています。

これは私のLINQです：

var data = (from candidateHP in _cempContexto.CandidateHiringProcessSummary 
       join jobsHP in _cempContexto.JobHiringProcessSummary on candidateHP.JobCode equals jobsHP.JobCode 
       join job in _cempContexto.Vaga on jobsHP.JobCode equals job.Codigo 
       join candidateJob in _cempContexto.TrCandidatoVaga on new { X = job.Codigo, Y = candidateCode } equals new { X = candidateJob.VagaCodigo, Y = candidateJob.CandidatoCodigo } 
       where 
       candidateHP.CandidateCode == candidateCode 
       select 
       new 
       { 
       JobCode = jobsHP.JobCode, 
       CompanyCode = job.EmpresaCodigo, 
       Title = job.Titulo, 
       HasImage = true, 
       CompanyName = job.NomeEmpresa, 
       QuantityJobs = job.QuantidadeVaga, 
       Location = job.CidadeCodigo, 
       QuantityResumeSent = jobsHP.QuantityResumeSent, 
       JobStatusCode = jobsHP.StatusCode, 
       CandidateStatusCode = candidateHP.StatusCode, 
       StatusCode = job.StatusCodigo, 
       ResumeSentDate = candidateJob.Data, 
       InsertDate = job.DataDeCadastro, 
       EndDate = job.DataDeSaida, 
       city= _cempContexto.TrVagaCidade.SelectMany(p => _cempContexto.TrVagaCidade.Where(q => q.VagaCodigo == candidateHP.JobCode).Select(q => new { q })).ToList() 
       }) 
       .ToList(); 

私はそのサブクエリで街を記入する必要があります。私はそれをするためのより良い方法が必要です、どのように進めることができますか？

2つのクエリに分割コード：

var query = (from candidateHP in _cempContexto.CandidateHiringProcessSummary 
       join jobsHP in _cempContexto.JobHiringProcessSummary on candidateHP.JobCode equals jobsHP.JobCode 
       join job in _cempContexto.Vaga on jobsHP.JobCode equals job.Codigo 
       join candidateJob in _cempContexto.TrCandidatoVaga on new { X = job.Codigo, Y = candidateCode } equals new { X = candidateJob.VagaCodigo, Y = candidateJob.CandidatoCodigo } 
       where 
       candidateHP.CandidateCode == candidateCode 
       select 
       new 
       { jobsHP = jobsHP, job = job, candidateJob = candidateJob}).ToList(); 

var data = query.Select(x => new { 
       JobCode = x.jobsHP.JobCode, 
       CompanyCode = x.job.EmpresaCodigo, 
       Title = x.job.Titulo, 
       HasImage = true, 
       CompanyName = x.job.NomeEmpresa, 
       QuantityJobs = x.job.QuantidadeVaga, 
       Location = x.job.CidadeCodigo, 
       QuantityResumeSent = x.jobsHP.QuantityResumeSent, 
       JobStatusCode = x.jobsHP.StatusCode, 
       CandidateStatusCode = x.candidateHP.StatusCode, 
       StatusCode = x.job.StatusCodigo, 
       ResumeSentDate = x.candidateJob.Data, 
       InsertDate = x.job.DataDeCadastro, 
       EndDate = x.job.DataDeSaida, 
       city= query.Select(y => y.candidateHP.JobCode).Select(q => new { q })).ToList() 
       }) 
       .ToList();
