如何在 Entity Framework CORE 中点赞(不完整的 .net)

How to do a LIKE in Entity Framework CORE (not full .net)

完整的 .net 框架中有 Entity Framework LIKE 的问答:

How to do SQL Like % in Linq?
Like Operator in Entity Framework?

例如:

from c in dc.Organization
where SqlMethods.Like(c.Boss, "%Jeremy%")

这在 EF Core 中不起作用:

The name SqlMethods does not exist in the current context.

那么如何使用 Entity Framework CORE 来点赞呢?

LIKE 函数已移至核心 EF.Functions 下:

from c in dc.Organization
where EF.Functions.Like(c.Boss, "%Jeremy%")

您可以使用 Contains

而不是 Like 函数
from c in dc.Organization
where c.Boss.Contains("Jeremy") 

流畅版:

dc.Organization.Where(o => EF.Functions.Like(o.Boss, "%Jeremy%"));
