c# - Any difference between QueryAsyc and querying the table using lambda?

Question

I'm using SQLite in a Windows 8 application I'm running and was wondering if there was any sort of performance issue between using the following two lines of code:

conn.Table<Chemistry>().Where(ch => ch.case_id == CaseId).ToListAsync();

vs

conn.QueryAsync<Chemistry>("SELECT * FROM Chemistry WHERE Case_Id = ?", CaseId);

They both work and I prefer to use the lambda expression as opposed to the string query. Just wondering if there are any repercussions when doing this.

见这里和这里。要点是，假设等效语句，它们产生相同的 IL，因此性能相同。有一些东西在查询表单中更容易表达。
