枚举器

The FromTo method in the example returns an enumerable object and is implemented using an iterator.

例子中的FromTo方法返回了一个用迭代器实现的可枚举对象。

Instead, an enumerable object is created and returned.

该可枚举对象有一个GetEnumerator方法，能够返回一个枚举器对象。

The FromTo method can be translated into an instantiation of a compiler-generated enumerable class that encapsulates the code in the iterator block, as shown in the following.

FromTo方法可以被转换为由编译器自动生成的可枚举类的实例，它封装了迭代器块中的代码，如下所示

An enumerable object is typically an instance of a compiler-generated enumerable class that encapsulates the code in the iterator block and implements the enumerable interfaces, but other methods of implementation are possible.

典型的可枚举对象是由编译器自动生成的封装了迭代器块中的代码并实现了可枚举接口的可枚举类的实例，但其他的实现也是允许的。

When a function member returning an enumerable interface type is implemented using an iterator block, invoking the function member does not immediately execute the code in the iterator block.

当一个返回一个可枚举接口类型的函数成员使用了迭代器块时，对该函数成员的调用不会立即执行迭代器块中的代码，而是建立并返回一个可枚举对象。

The enumerable object's GetEnumerator method returns an enumerator object that encapsulates the code specified in the iterator block, and execution of the code in the iterator block occurs when the enumerator object's MoveNext method is invoked.

该枚举器对象封装了迭代器块中指定的代码，当调用这个枚举器对象的MoveNext方法时，会执行迭代器块中的代码。

This is because the bus enumerator also loads services.

这是因为总线枚举器也有加载服务功能。

Thus, each returned enumerator has its own state and changes in one enumerator will not affect another.

因此，每个被返回的枚举器具有其自己的状态，并且一个枚举器和其它枚举器互不影响。

Now this is pretty useless without some way of using the array; that's why there is an array enumerator.

而如果我们没有啥特定方法使用这个数组，那就几乎没用；这就是要用到数组枚举器的地方。

According to the appointed carrier mission and setting the pay load of the space transportation craft as objective function, energy characteristic model, mass model and orbit model of the hydrogen-oxygen FFSC (Full Flow Staged-Combustion Cycle) were established, and the numerical method was used to optimize the performance parameters.

根据给定的运载任务，建立了氢氧全流量补燃循环发动机的能量特性模型、运载器质量模型和轨道模型，以运载器有效载荷为目标函数，利用枚举法进行了发动机性能参数的优化研究。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
