警告

BinaryFormatter 不安全，无法确保安全。有关详细信息，请参阅 BinaryFormatter 安全指南。

SoapFormatter和 BinaryFormatter 类实现 IRemotingFormatter 接口以支持远程过程调用 (RPC) ，) IFormatter 继承IRemotingFormatter的接口 (支持对象图的序列化。类 SoapFormatter 还支持包含 ISoapMessage 对象的 RPC，而不使用 IRemotingFormatter 功能。

在 RPC 期间， IRemotingFormatter 接口允许指定两个单独的对象图：要序列化的对象图，以及包含标头对象数组的附加图形，这些对象 (例如事务 ID 或方法签名) 。为了进行适当的序列化，第一个图形的根对象必须是实现 IMethodCallMessage 接口或接口的对象 IMethodReturnMessage 。

在反序列化 RPC 期间， HeaderHandler 将委托指定给 Deserialize 格式化程序的方法。远程处理基础结构使用 HeaderHandler 委托生成支持接口的对象 ISerializable 。此对象包含标头中存储的信息，并成为反序列化程序返回的图形的根。

SoapFormatter还可以处理由实现 ISoapMessage 接口的对象生成的 RPC。若要在 IRemotingFormatter 不使用该功能的情况下创建 RPC，请将支持 ISoapMessage 接口的对象放置在要序列化的图形的根目录中。若要反序列化以这种方式创建的 RPC， TopObject 必须将属性设置为支持接口 ISoapMessage 的另一个对象，并包含相关的远程调用信息。

TimeSpan 对象根据 ISO 8601：1998 第 5.5.3.2.1 节“替代”标准进行序列化。
