ContractReference クラス

探索ドキュメント内にあるサービスの説明への参照を表します。

名前空間: System.Web.Services.Discovery
アセンブリ: System.Web.Services (system.web.services.dll 内)
構文

Visual Basic (宣言)

Public Class ContractReference
    Inherits DiscoveryReference

Visual Basic (使用法)

Dim instance As ContractReference

public class ContractReference : DiscoveryReference

C++

public ref class ContractReference : public
 DiscoveryReference

public class ContractReference extends DiscoveryReference

JScript

public class ContractReference extends
 DiscoveryReference

解説

XML Web サービス探索には、指定 URL で使用できる Web サービスの探索が含まれます。通常、URL は探索ドキュメントを指します。探索ドキュメントのファイル名拡張子は通常 .disco です。探索ドキュメントには、XML Web サービスが存在するかどうかに関する情報への参照が含まれています。これらの参照は、サービスの説明、XML スキーマ定義言語 (XSD) スキーマ、または他の探索ドキュメントを参照できます。このクラスは、サービスの説明への参照を表します。

探索ドキュメント内では、サービスの説明への参照は contractRef XML 要素に格納されています。contractRef XML 要素には ref と docRef の 2 つの属性があります。contractRef 要素は Namespace 定数と一致する XML 名前空間を持っている必要がありますが、ref 属性と docRef 属性は Ref プロパティと DocRef プロパティに設定されます。
