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

参数

type

Type

为其请求代理项的 Type。

context

StreamingContext

流上下文。

selector

ISurrogateSelector

要使用的代理项。

返回

ISerializationSurrogate

特定类型的代理项。

实现
