.NET Framework クラス ライブラリ リファレンス

DiscoveryClientProtocol.Errors プロパティ

このクラスからメソッドを呼び出したときに発生した例外のコレクションを取得します。

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 ReadOnly Property
 Errors As DiscoveryExceptionDictionary

Visual Basic (使用法)

Dim instance As DiscoveryClientProtocol
Dim value As DiscoveryExceptionDictionary

value = instance.Errors

C#

public DiscoveryExceptionDictionary Errors { get;
 }

C++

public:
property DiscoveryExceptionDictionary^ Errors {
    DiscoveryExceptionDictionary^ get ();
}

J#

/** @property */
public DiscoveryExceptionDictionary get_Errors ()

JScript

public function get Errors
 () : DiscoveryExceptionDictionary

プロパティ値
例外の DiscoveryExceptionDictionary。

解説

Errors コレクションは Discover、DiscoverAny、ResolveAll、ResolveOneLevel の各メソッドの呼び出し時に発生した例外から作成されます。これらのメソッドが呼び出されると DiscoveryExceptionDictionary はクリアされます。
