C# 帮助我使用EntityFramework将SQL转换为linq嵌套lambda表达式

我试图从SQL中获取一些数据，但我无法使用Linq，在T-SQL中，这项工作：

select *
from MTRBatch MB
Inner Join MTR M on MB.Id = M.MTRBatchId
Inner JOIN MTRHeats MH on M.Id = MH.MTRId
LEFT OUTER JOIN Vendor V on MB.VendorId = v.Id
Inner Join Manufacturer MF on MB.ManufacturerId = MF.Id
Where MB.ManufacturerId = 1
AND MH.Heat = 'z01'

除了那个过滤器，我需要所有的树

我尝试了这个，但没有成功：

MTRBatches
.Include(x => x.MTRs.Select(m => m.MTRHeats))
.Include(x => x.Manufacturer)
.Include(x => x.Vendor)
.Where(x => (x.Manufacturer.Id == 1));
.Where(x => x.MTRs.Any(m => m.MTRHeats.Any(h => h.Heat == 'z01')));

---

这应该会有所帮助

dataContext

是

实体框架容器的实例名

var result = dataContext.MTRBatches
    .Join(dataContext.MTRs,
        mb => mb.Id,
        mtr => mtr.MTRBatchId,
        (mb, mtr) => new{ Batch = mb, MTR = mtr })
    .Join(dataContext.MTRHeats,
        x => x.MTR.Id,
        mh => mh.MTRId,
        (x, mh) => new{ Batch = x.Batch, MTR = x.MTR, Heat = mh })
    .Join(dataContext.Vendors.DefaultIfEmpty(),
        x => x.Batch.VendorId,
        v => v.Id,
        (x, v) => new{ Batch = x.Batch, MTR = x.MTR, Heat = x.Heat, Vendor = v })
    .Join(dataContext.Manufacturers,
        x => x.Batch.ManufacturerId,
        mf => mf.Id,
        (x, mf) => new{ Batch = x.Batch, MTR = x.MTR, Heat = x.Heat, Vendor = x.Vendor, Manufacturer = mf})
    .Where(x => x.Manufacturer.Id == 1 && x.Heat.Heat == "z01");

没有像在。。。？错误的结果？撞车烧伤？没有编译？结果不正确：它给我带来了所有的MTR，就像MH。热过滤器没有发生一样
