SinkProviderData クラス

シンク プロバイダのシンク プロバイダ データを格納します。

名前空間: System.Runtime.Remoting.Channels
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

<ComVisibleAttribute(True)> _
Public Class SinkProviderData

Visual Basic (使用法)

Dim instance As SinkProviderData

C#

[ComVisibleAttribute(true)] 
public class SinkProviderData

C++

[ComVisibleAttribute(true)] 
public ref class SinkProviderData

J#

/** @attribute ComVisibleAttribute(true) */ 
public class SinkProviderData

JScript

ComVisibleAttribute(true) 
public class SinkProviderData

解説

シンク プロバイダ データは、<provider> 要素 (テンプレート) 構成ノードに格納されているツリー構造の構成情報です。すべてのシンク プロバイダを構成ファイルから使用する場合、すべてのシンク プロバイダは、プロパティの IDictionary およびこれらの構造体の ICollection を受け入れるコンストラクタを持つ必要があります。
