SchemaReference.Schema プロパティ

XSD スキーマを表す XmlSchema オブジェクトを取得します。

Public ReadOnly Property Schema As XmlSchema
[C#]
public XmlSchema Schema {get;}
[C++]
public: __property XmlSchema* get_Schema();
[JScript]
public function get Schema() : XmlSchema;

プロパティ値

XSD スキーマを表す XmlSchema オブジェクト。

例外

例外の種類	条件
InvalidOperationException	ClientProtocol プロパティが null 参照 (Visual Basic では Nothing) です。 または ClientProtocol を使用した XSD スキーマのダウンロードまたは解決の実行中に、エラーが発生しました。

解説

まだ XSD スキーマをダウンロードして ClientProtocol の Documents プロパティに追加していない場合は、ドキュメントをダウンロードして解決しようとします。
