このセクションには、2 つの例が含まれています。This section contains two examples. 最初の例では、標準の X.509 ストアと証明書の数の一覧を開く各する方法を示します。The first example demonstrates how you can open standard X.509 stores and list the number of certificates in each.

2 番目の例では、追加および 1 つの証明書と証明書の範囲を削除する方法を示します。The second example demonstrates how you can add and remove single certificates and ranges of certificates.

例 1Example 1

この例では、現在のコンピューターで標準的な各場所で各標準的なストアを開こうとします。This example tries to open each standard store in each standard location on the current computer. 各ストアが存在しが含まれる場合の数がそれを証明書、かどうかを示す概要を出力します。It prints a summary that shows whether each store exists and, if so, the number of certificates it contains.

例は、作成、X509Store標準の名前と標準の場所の組み合わせごとのオブジェクト。The example creates an X509Store object for each combination of standard name and standard location. 呼び出す、OpenメソッドをOpenFlags.OpenExistingOnlyフラグは、既に存在する場合にのみ、物理ストアを開きます。It calls the Open method with the OpenFlags.OpenExistingOnly flag, which opens the physical store only if it already exists. 例では、物理ストアに存在する場合、 NameLocation、およびCertificatesストアに証明書の数を表示するプロパティ。If the physical store exists, the example uses the Name, Location, and Certificates properties to display the number of certificates in the store.

以降では、 .NET Framework 4.6.NET Framework 4.6、この実装の入力、IDisposableインターフェイス。Starting with the .NET Framework 4.6.NET Framework 4.6, this type implements the IDisposable interface. 型の使用が完了したら、直接的または間接的に型を破棄する必要があります。When you have finished using the type, you should dispose of it either directly or indirectly. 直接的に型を破棄するには、try / catch ブロック内で Dispose メソッドを呼び出します。To dispose of the type directly, call its Dispose method in a try/catch block. 間接的に型を破棄するには、using (C# の場合) または Using (Visual Basic 言語) などの言語構成要素を使用します。To dispose of it indirectly, use a language construct such as using (in C#) or Using (in Visual Basic). 詳細については、IDisposable インターフェイスに関するトピック内の「IDisposable を実装するオブジェクトの使用」セクションを参照してください。For more information, see the "Using an Object that Implements IDisposable" section in the IDisposable interface topic.

対象とするアプリ、.NET Framework 4.5.2.NET Framework 4.5.2以前のバージョン、X509Storeクラスは実装しない、IDisposableインターフェイスし、したがって必要はありません、Disposeメソッド。For apps that target the .NET Framework 4.5.2.NET Framework 4.5.2 and earlier versions, the X509Store class does not implement the IDisposable interface and therefore does not have a Dispose method.
