将IEnumerable<T>强制转换为ObservableCollection<T>,而不使用构造函数注入IEnumerable<T>

observeCollection obsCol=新的observeCollection(myIEnumerable);

脚本:

var query = from c in customers
                    select new Customer()
                    {
                       Products = from p in products
                                  where p.Id = c.Id
                                  select p
};
