For example, a constraint may disallow multiple inheritance, or it may require that a class must have a particular type of attribute. This means that.
例如，一个限制可能不允许多重继承，或者是它可能需要一个类必须具备一个特殊的属性类型。

Often this will lead to a proliferation of classes, in which case the constraint must be implemented in the behavior of the class-usually, but not necessarily, in the constructor.
这常常会导致类泛滥成灾，在这种情况下，约束应当在类的行为中实现，通常是在构造函数中实现，但不是必须如此。
If you own the class, you can remove the constraint or else do something to enable an implicit reference or identity conversion.
如果您拥有类，则可移除约束或执行某一操作以启用隐式引用或标识转换。
For example, if you know that your generic class is intended for use only with reference types, apply the class constraint.
例如，如果您知道您的泛型类仅用于引用类型，则应用类约束。
