CspKeyContainerInfo クラス
アセンブリ: mscorlib (mscorlib.dll 内)
構文
解説このクラスを使用して、キー コンテナ名やキー番号など、キー ペアに関する追加情報を取得します。
ランダム キーが RSACryptoServiceProvider または DSACryptoServiceProvider によって生成された場合、キーを使用するメソッドを呼び出すまでキー コンテナは作成されません。CspKeyContainerInfo クラスの一部のプロパティは、キー コンテナが作成されていない場合に CryptographicException をスローします。
使用例キー コンテナを作成して、そのコンテナに関する情報を取得するコード例を次に示します。
