是否有 Z.EntityFramework.Extensions 的非商业替代品?

问题描述

实体框架在批量插入/更新/删除操作时可能会非常慢.即使是经常建议的关闭 AutoDetectChanges 和/或 ValidateOnSaveEnabled 的调整也并不总是有帮助.

Entity Framework can be very slow on mass insert/update/delete operations. Even the often suggested tweaks to turn off AutoDetectChanges and/or ValidateOnSaveEnabled does not always help.

我在 NuGet 上遇到过 Z.EntityFramework.Extensions，但它似乎是一个商业产品，只能在一段时间内工作.

I have come across the Z.EntityFramework.Extensions on NuGet, but it seems to be a commercial product, which will only work for a certain period of time.

https://www.nuget.org/packages/Z.EntityFramework.Extensions/

到目前为止，我真的只需要 BulkInsert()、BulkUpdate() 和 BulkDelete().

So far, I really only need BulkInsert(), BulkUpdate() and BulkDelete().

我的问题是:

是否有任何可靠的非商业库，其功能与 Z.EntityFramework.Extensions 几乎相同?

感谢任何提示！

推荐答案

免责声明:我是 实体框架扩展

你是对的.这是一个商业产品.

You are right. This is a commercial product.

每个月都提供免费试用，但您必须为生产环境购买产品.

批量插入

对于 BulkInsert，有一些免费的替代方案，但要小心，它们不支持所有继承 &关联并且不再受支持:

For BulkInsert, there are some free alternatives but be careful, they don't support all inheritances & associations and are no longer supported:

• https://www.nuget.org/packages/EntityFramework.BulkInsert-ef6
• https://github.com/MikaelEliasson/EntityFramework.Utilities

免责声明:我是Entity Framework Plus的所有者

用于批量更新&&批量删除，可以使用这个库:

For Batch Update && Batch Delete, you can use this library:

// DELETE all users which has been inactive for 2 years
ctx.Users.Where(x => x.LastLoginDate < DateTime.Now.AddYears(-2))
         .Delete();

// UPDATE all users which has been inactive for 2 years
ctx.Users.Where(x => x.LastLoginDate < DateTime.Now.AddYears(-2))
         .Update(x => new User() { IsSoftDeleted = 1 });
