多表左外关联带右表条件的SQL转LINQ求助

Hey there! It sounds like you're stuck getting your SQL-to-LINQ conversion to work in Visual Studio, even after trying tools like LINQPad and Linqer and referencing that article about left outer joins with right-table WHERE clauses. To help you fix this effectively, could you share a few key details?

• Your original SQL query: Seeing the exact joins, filters, and columns you're selecting will let me map the logic accurately to LINQ.
• The two LINQ attempts you wrote that are throwing errors: Sharing your code will help spot syntax mistakes, incorrect join logic, or mismatches with your project's data context setup.
• The specific error messages from Visual Studio: Whether it's a compile-time error (like syntax issues) or runtime error (like null references, unexpected results), these details are critical to pinpointing the root problem.

Tools like Linqer often generate verbose or context-unaware LINQ code that might not play nicely with your project's specific data model nuances, so having your actual code and errors will let us tweak it to work correctly.
