Dapper-将整个实体作为查询参数或匿名对象传递

Question

I want to know if there are any recommendations with query parameters

Is it ok to pass the whole object or is it better to create a lightweight anonymous object with properties I need?

Query<SomeObj>("Select * from SomeObjs where Id = @Id", someObj);

or

Query<SomeObj>("Select * from SomeObjs where Id = @Id", new {someObj.Id});

Are there any performance or memory implications for one over other?

对于Dapper的工作方式，通过在首次使用时动态创建和缓存映射代码，就没关系了。
