.net Linq多表组合查询结果集

背景：

主流程表中包含员工ID及流程类型ID，在页面查看流程是需要显示员工姓名及流程名称

操作：

 //先进行分页处理原始数据
            var result = from p in _dbContext.Set<BeWorkflowContent>()
                         select p;
            if (searchWhere != null)
                result = result.Where(searchWhere);
            if (order != null)
                result = result.OrderByDescending(order);
            rowCount = result.Count();
            
            //多表查询组装最后的数据模型
            var query = from a in result
                        join b in _dbContext.BeUser on a.UserId equals b.UserId
                        join c in _dbContext.BeWorkflow on a.WorkflowId equals c.WorkflowId
                        select new WorkFlowContentV()
                        {
                            CustomerName = a.CustomerName,
                            WorkflowContentId = a.WorkflowContentId,
                            CarType = a.CarType,
                            CarStyle = a.CarStyle,
                            CarLicense = a.CarLicense,
                            UserName = b.TrueName,
                            WorkflowName = c.WorkflowName
                        };
            return query.ToList();

PS：select new之后一定要加对应的类名，不然返回后就是对象转换时会有问题
