Type.GetProperties メソッド
現在の Type のプロパティを取得します。
オーバーロードの一覧
現在の Type のすべてのパブリック プロパティを返します。
.NET Compact Framework でもサポート。
[Visual Basic] Overloads Public Function GetProperties() As PropertyInfo()
派生クラスによってオーバーライドされた場合、指定したバインディング制約を使用して、現在の Type のプロパティを検索します。
.NET Compact Framework でもサポート。
[Visual Basic] Overloads Public MustOverride Function GetProperties(BindingFlags) As PropertyInfo() Implements IReflect.GetProperties
[C#] public abstract PropertyInfo[] GetProperties(BindingFlags);
[C++] public: virtual PropertyInfo* GetProperties(BindingFlags) [] = 0;
[JScript] public abstract function GetProperties(BindingFlags) : PropertyInfo[];
使用例
[Visual Basic, C#, C++] 2 つのパブリック プロパティと 1 つのプロテクト プロパティを作成し、指定したバインディング制約に一致するプロパティの情報を表示する例を次に示します。
[Visual Basic, C#, C++] メモ ここでは、GetProperties のオーバーロード形式のうちの 1 つだけについて、使用例を示します。その他の例については、各オーバーロード形式のトピックを参照してください。
