X509Store.Open(OpenFlags) 方法
定義
重要
部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
開啟 X.509 憑證存放區或建立新的存放區 (視 OpenFlags 旗標設定而定)。
public:
void Open(System::Security::Cryptography::X509Certificates::OpenFlags flags);
public void Open (System.Security.Cryptography.X509Certificates.OpenFlags flags);
member this.Open : System.Security.Cryptography.X509Certificates.OpenFlags -> unit
Public Sub Open (flags As OpenFlags)
參數
- flags
- OpenFlags
列舉值的位元組合,指定開啟 X.509 憑證存放區的方式。
例外狀況
存放區無法如要求開啟。
呼叫端沒有必要的權限。
此存放區包含無效的值。
範例
下列程式代碼範例會開啟 X.509 證書存儲、新增和刪除憑證,然後關閉存放區。 它假設您有三個憑證可新增至本機存放區並從本機存放區中移除。

備註
使用此方法開啟現有的 X.509 存放區。 請注意,您必須擁有 所 StorePermissionFlags指定的其他許可權,才能列舉存放區中的憑證。 您可以將不存在的存放區名稱傳遞至類別建構函式,然後使用除了 以外的OpenExistingOnly任何OpenFlags旗標,來建立新的存放區。
