如果没有beforefieldinit，运行库就必须在某个精确时间运行类型构造函数，即，恰好在第一次访问该类型的静态或实例字段和方法之前。

Without beforefieldinit, the runtime must run the type constructor at a precise time-just before the first access to static or instance fields and methods of the type.

我们将创建measurementmanager类，它带有一些静态方法，用于获取和返回可重用的Measurement实例。

We'll create the MeasurementManager class with some static methods for getting and returning reusable Measurement instances.

这种做法并不常见，因为需要开发人员创建仅用于访问非实例(静态)方法和字段的对象的实例。

This is unusual because it requires a developer to create an instance of an object just to access non-instance (static) methods and fields!
