SoapAttributeOverrides.Item プロパティ (Type)

[アーティクル]
03/28/2008

指定された型 (基本クラス) に関連付けられているオブジェクトを取得します。

[C#] C# では、このプロパティは SoapAttributeOverrides クラスのインデクサになります。

Overloads Public Default ReadOnly Property Item( _
   ByVal type As Type _) As SoapAttributes
[C#]
public SoapAttributes this[Typetype] {get;}
[C++]
public: __property SoapAttributes* get_Item(Type* type);
[JScript]
returnValue = SoapAttributeOverridesObject.Item(type);またはreturnValue = SoapAttributeOverridesObject(type);

[JScript] JScript では、この型で定義されている既定のインデックスプロパティを使用することができます。しかし、独自のインデックスプロパティを明示的に定義することはできません。ただし、このクラスの expando 属性を指定すると、既定のインデックスプロパティが提供されます。提供されるインデックスプロパティの型は Object 型であり、インデックス型は String になります。

引数 [JScript]

type
取得する属性のコレクションに関連付けられている基本クラスのクラス Type 。

パラメータ [Visual Basic, C#, C++]

type
取得する属性のコレクションに関連付けられている基本クラスのクラス Type 。

プロパティ値

オーバーライドする側の属性のコレクションを表す SoapAttributes 。

解説

SoapTypeAttribute の属性を格納している SoapAttributes を返すには、このオーバーロードを使用します。

使用例

[Visual Basic, C#, C++] Group クラスのインスタンスのシリアル化をオーバーライドするために使用される SoapAttributeOverrides の作成例を次に示します。この例では、 Item プロパティを使用して、シリアル化のオーバーライドを指定するために使用される SoapAttributes の取得も行っています。
