Serialize(Stream, Object, Header[])

Serialize(Stream, Object)

将对象或具有指定顶级(根)的对象图形序列化为给定流。Serializes the object, or graph of objects with the specified top (root), to the given stream.

public:
 virtual void Serialize(System::IO::Stream ^ serializationStream, System::Object ^ graph);
public void Serialize (System.IO.Stream serializationStream, object graph);
abstract member Serialize : System.IO.Stream * obj -> unit
override this.Serialize : System.IO.Stream * obj -> unit
Public Sub Serialize (serializationStream As Stream, graph As Object)

参数

serializationStream
Stream

图形要序列化为的流。The stream to which the graph is to be serialized.

graph
Object

位于要序列化图形的根位置的对象。The object at the root of the graph to serialize.

实现

异常

serializationStreamnullThe serializationStream is null.

-或--or- graph 为 null。The graph is null.

序列化期间发生错误,如 graph 参数中的某个对象未标记为可序列化。An error has occurred during serialization, such as if an object in the graph parameter is not marked as serializable.

调用方没有所要求的权限。The caller does not have the required permission.

Serialize(Stream, Object, Header[])

将对象或具有指定顶级(根)的对象图形序列化为附加所提供标题的给定流。Serializes the object, or graph of objects with the specified top (root), to the given stream attaching the provided headers.

public:
 virtual void Serialize(System::IO::Stream ^ serializationStream, System::Object ^ graph, cli::array <System::Runtime::Remoting::Messaging::Header ^> ^ headers);
public void Serialize (System.IO.Stream serializationStream, object graph, System.Runtime.Remoting.Messaging.Header[] headers);
abstract member Serialize : System.IO.Stream * obj * System.Runtime.Remoting.Messaging.Header[] -> unit
override this.Serialize : System.IO.Stream * obj * System.Runtime.Remoting.Messaging.Header[] -> unit
Public Sub Serialize (serializationStream As Stream, graph As Object, headers As Header())

参数

serializationStream
Stream

对象要序列化为的流。The stream to which the object is to be serialized.

graph
Object

位于要序列化图形的根位置的对象。The object at the root of the graph to serialize.

headers
Header[]

将包括在序列化中的远程处理标题。Remoting headers to include in the serialization. 可以为 nullCan be null.

实现

异常

serializationStreamnullThe serializationStream is null.

序列化期间发生错误,如 graph 参数中的某个对象未标记为可序列化。An error has occurred during serialization, such as if an object in the graph parameter is not marked as serializable.

调用方没有所要求的权限。The caller does not have the required permission.

注解

序列化过程包括序列化流前面 headers 参数中提供的信息。The serialization process includes the information supplied in the headers parameter at the front of the serialized stream.

标头仅用于特定的远程处理应用程序。Headers are used only for specific remoting applications.
