2 classes
Supplier(Name:string)
SupplierImage(Link:string; Supplier:pointer)

我有多个supplier的objectId，比如['XXXXXXXX', 'AAAAAAAAA']
如何检索出所有的SupplierImage其中它文字缩进4格的Supplier的ObjectId是以上['XXXXXXXX', 'AAAAAAAAA']里面的?

使用WhereContainedIn不成功

List<string> aaa=new[]{"XXXXXX","AAAAA"};
AVQuery<AVObject> querySupplierImages = AVObject.GetQuery("SupplierImage")
.WhereContainedIn("Supplier", aaa.Select(id=>AVObject.CreateWithoutData("Supplier", id)));
