C# Exception的子类Serializable警告

编译时发出的警告：
警告 CA2237[1] 将 [Serializable] 添加到 'HardwareException'，原因是此类型实现了 ISerializable。

Cause[1]

---

An externally visible type implements the System.Runtime.Serialization.ISerializable interface and the type is not marked with the System.SerializableAttribute attribute. The rule ignores derived types whose base type is not serializable.

Rule Description 

---

To be recognized by the common language runtime as serializable, types must be marked with the SerializableAttribute attribute even if the type uses a custom serialization routine through implementation of the ISerializable interface.

 

How to Fix Violations

---

To fix a violation of this rule, apply the SerializableAttribute attribute to the type.
