我需要帮助将 SQL 语句转换为 C# LINQ

Question

I need help with Converting this Select statement in LINQ C# Code

SELECT TagName 
from Tags 
Where TagId IN(
    SELECT TagId 
    from PresentationTags 
    Where PresentationId = 2
)

Answer 1

Where() with nested Any() should do the job

context.Tags.Where(
    x => context.PresentationTags.Any(
        y => y.PresentationId == 2 && x.TagId == y.TagId
    )
).Select(x => x.TagName);
