Public Function GetSurrogate (type As Type, context As StreamingContext, ByRef selector As ISurrogateSelector) As ISerializationSurrogate

参数

type

Type

需要代理项的对象（类）的 Type。

context

StreamingContext

当前序列化的源或目标上下文。

selector

ISurrogateSelector

当此方法返回时，将包含一个 ISurrogateSelector，它持有一个指向从中找到合适代理项的代理项选择器引用。 此参数未经初始化即被传递。

返回

ISerializationSurrogate

给定上下文中给定类型的适当代理项。

属性

SecurityCriticalAttribute

例外

SecurityException
