SoapFormatter コンストラクタ (ISurrogateSelector, StreamingContext)

指定した ISurrogateSelector と StreamingContext を使用して、SoapFormatter クラスの新しいインスタンスを初期化します。

名前空間: System.Runtime.Serialization.Formatters.Soap
アセンブリ: System.Runtime.Serialization.Formatters.Soap (system.runtime.serialization.formatters.soap.dll 内)
構文

Visual Basic (宣言)

Public Sub New ( _
    selector As ISurrogateSelector, _
    context As StreamingContext _
)

Visual Basic (使用法)

Dim selector As ISurrogateSelector
Dim context As StreamingContext

Dim instance As New SoapFormatter(selector,
 context)

public SoapFormatter (
    ISurrogateSelector selector,
    StreamingContext context
)

C++

public:
SoapFormatter (
    ISurrogateSelector^ selector, 
    StreamingContext context
)

public SoapFormatter (
    ISurrogateSelector selector, 
    StreamingContext context
)

JScript

public function SoapFormatter (
    selector : ISurrogateSelector, 
    context : StreamingContext
)

パラメータ

selector: SoapFormatter の新しいインスタンスで使用する ISurrogateSelector。null 参照 (Visual Basic では Nothing) でもかまいません。

context: シリアル化の転送元および転送先を保持する StreamingContext。context パラメータが null 参照 (Visual Basic では Nothing) の場合、Context は既定で CrossMachine に設定されます。

解説

オブジェクトは、指定した Stream を使用してシリアル化または逆シリアル化されます。

シリアル化処理または逆シリアル化処理では、指定した ISurrogateSelector を使用して、逆シリアル化するオブジェクト型用に登録されているサロゲートを検索します。サロゲートは、特定のクラスのオブジェクトをシリアル化および逆シリアル化するためのヘルパです。既定の ISurrogateSelector では、MarshalByRefObject から派生したオブジェクトをリモート処理の目的でシリアル化することはできません。リモート処理を行う場合は、指定した ISurrogateSelector が、MarshalByRefObject から派生したオブジェクトを、指定したサロゲートセレクタによってシリアル化された ObjRef オブジェクトに置換します。つまり、リモートオブジェクトを使用する場合は、selector パラメータに RemotingSurrogateSelector のインスタンスを設定します。サロゲートが不要な場合は、selector パラメータを null 参照 (Visual Basic では Nothing) に設定します。
