Entity framework 6 IncludeFilter多个级别不工作

此IncludeFilter存在问题，并且包含多个级别。我使用的是EntityFramework6Plus

这是他们在“加载多个级别”标题下提供的示例

这是可行的，但它返回的保修记录比我想要的多

db.Application.Where(x => x.ApplicationId == applicationId)
    .Include(x => x.Lienholder)
    .Include(x => x.Warranty.Select(y => y.Coverage.CoverageGroup))
    .Include(x => x.Vehicle)
    .Include(x => x.Vendor)
    .First();

这是可行的，但是

.Coverage

为空，但它是最接近示例的

db.Application.Where(x => x.ApplicationId == applicationId)
    .Include(x => x.Lienholder)
    .IncludeFilter(x => x.Warranty.Where(z => true).Where(z =>
        z.WarrantyStatusId == 2 ||
        z.WarrantyStatusId == 3 ||
        z.WarrantyStatusId == 8 ||
        z.WarrantyStatusId == 10
    )
    .IncludeFilter(x => x.Warranty.Where(z => true).Where(z =>
        z.WarrantyStatusId == 2 ||
        z.WarrantyStatusId == 3 ||
        z.WarrantyStatusId == 8 ||
        z.WarrantyStatusId == 10
    ).Select(y => y.Coverage.CoverageGroup))
    .Include(x => x.Vehicle)
    .Include(x => x.Vendor)
    .First();

这根本不起作用，因为显然在

IncludeFilter

中必须包含where子句

db.Application.Where(x => x.ApplicationId == applicationId)
    .Include(x => x.Lienholder)
    .IncludeFilter(x => x.Warranty.Where(z => true).Where(z =>
        z.WarrantyStatusId == 2 ||
        z.WarrantyStatusId == 3 ||
        z.WarrantyStatusId == 8 ||
        z.WarrantyStatusId == 10
    ).Select(y => y.Coverage.CoverageGroup))
    .Include(x => x.Vehicle)
    .Include(x => x.Vendor)
    .First();

这一个工作，但它不急于加载覆盖率

db.Application.Where(x => x.ApplicationId == applicationId)
    .Include(x => x.Lienholder)
    .IncludeFilter(x => x.Warranty.Where(z => true).Where(z =>
        z.WarrantyStatusId == 2 ||
        z.WarrantyStatusId == 3 ||
        z.WarrantyStatusId == 8 ||
        z.WarrantyStatusId == 10
    )
    .Include(x => x.Vehicle)
    .Include(x => x.Vendor)
    .First();

• 不能将

  Include

  与

  IncludeFilter

  或

  IncludeOptimized

  混合使用
• 您需要在其自己的

  IncludeFilter

在最近的示例中，您没有包括“Y.Coverage”

这些都是目前图书馆的局限性

以下是您正在寻找的内容：

db.Application.Where(x => x.ApplicationId == applicationId)
    .IncludeFilter(x => x.Lienholder)
    .IncludeFilter(x => x.Warranty.Where(z =>
        z.WarrantyStatusId == 2 ||
        z.WarrantyStatusId == 3 ||
        z.WarrantyStatusId == 8 ||
        z.WarrantyStatusId == 10
    ))
    .IncludeFilter(x => x.Warranty.Where(z => true).Where(z =>
        z.WarrantyStatusId == 2 ||
        z.WarrantyStatusId == 3 ||
        z.WarrantyStatusId == 8 ||
        z.WarrantyStatusId == 10
    ).Select(y => y.Coverage))
    .IncludeFilter(x => x.Warranty.Where(z => true).Where(z =>
        z.WarrantyStatusId == 2 ||
        z.WarrantyStatusId == 3 ||
        z.WarrantyStatusId == 8 ||
        z.WarrantyStatusId == 10
    ).Select(y => y.Coverage.CoverageGroup)))
    .IncludeFilter(x => x.Vehicle)
    .IncludeFilter(x => x.Vendor)
    .First();

这根本不起作用，因为显然对于IncludeFilter，您必须包含where子句

db.Application.Where(x => x.ApplicationId == applicationId)
    .Include(x => x.Lienholder)
    .IncludeFilter(x => x.Warranty.Where(z => true).Where(z =>
        z.WarrantyStatusId == 2 ||
        z.WarrantyStatusId == 3 ||
        z.WarrantyStatusId == 8 ||
        z.WarrantyStatusId == 10
    ).Select(y => y.Coverage.CoverageGroup))
    .Include(x => x.Vehicle)
    .Include(x => x.Vendor)
    .First();

不，您没有。

这是正确的，只是有一个括号不平衡，我无法修复，因为显然我需要超过六个字符。也许管理员可以修复它？这是正确的，但有一个括号不平衡，我无法修复，因为显然我需要超过六个字符。也许管理员可以解决它？
