问题描述
我需要将 [Serializable] 属性添加到对性能极为敏感的类.
I need to add the [Serializable] attribute to a class that is extremely performance sensitive.
这个属性会对类的操作产生任何性能影响吗?
Will this attribute have any performance implications on the operation of the class?
推荐答案
属性类的实例仅在首次访问时创建.如果您不对特定类进行任何序列化，则永远不会调用 SerializableAttribute() 构造函数，因此不会导致任何性能问题.
Instances of attribute classes are only created when they're first accessed. If you don't do any serialization on that particular class, the SerializableAttribute() constructor will never be called, hence it won't cause any performance issues.
