Notice that the typical PHP array that results from an SQL query (where the keys match database field names and the values match the data) is easily transported as a JSON object.
注意，一个SQL查询(其中键等于数据库字段名、值等于数据)生成的典型php数组可以作为一个JSON对象轻松传输。
On the other hand, that's no worse than the current situation; you can't pass an int as a key to Hashtable because all keys must be of type Object.
另一方面，当前的这种情况是最糟的；您不能将int作为键传递给Hashtable，因为所有的键都必须是Object类型。

Just think of the Preferences object as one big key-value hashtable that structures the keys in a tree-like structure.
只要把Preferences对象当作一个大的键—值散列表(这个表把树形结构中的键组织起来)。
Each element object has an attributes object which is a hash of the element attribute names as keys and their values as values.

ONE of the keys for getting data easily to a view is that we need to send ONE object (and not an anonymous type) to the view.
若要轻易地获取数据并将其传给视图，则其中一个关键是我们需要传递“一个”对象(而且不是匿名类型)到视图。
Clearly, the old rules regarding primary keys aren't in force here; so how does an object database deal with notions of uniqueness?
很明显，这里并不强制使用关于主键的旧规则，那么对象数据库如何处理惟一性概念？
In addition to creating request scope keys, MyRequestProcessor needs to get the application scope key and session scope key and store them in a RequestContext object before a request is processed.
除了创建请求范围键之外，在处理请求之前，MyRequestProcessor需要获得应用程序范围键和会话范围键，并把它们存储在RequestContext对象中。
If the positional argument is a mapping object, return a dictionary mapping the same keys to the same values as does the mapping object.
如果位置参数是一个映射对象，则返回像映射对象一样的键值映射。

Is there any standard method to get array of objects from object with indexer by range of index keys?
有没有标准的方法，通过索引键的范围从对象和对象数组的索引？
Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key.
如果元组中只包含字符串和数字，它可以做为关键字，如果它直接或间接的包含了可变对象，就不能当做关键字。
