指定開啟 X.509 憑證存放區的方法。

此列舉支援其成員值的位元組合。

欄位

IncludeArchived	8	開啟 X.509 憑證存放區並加入封存的憑證。
MaxAllowed	2	開啟最高存取權所允許的 X.509 憑證存放區。
OpenExistingOnly	4	開啟僅有的存放區。如果沒有存放區，Open(OpenFlags) 方法也不會建立新的存放區。
ReadOnly	0	開啟只用於讀取的 X.509 憑證存放區。
ReadWrite	1	開啟同時用於讀取和寫入的 X.509 憑證存放區。

範例

下列程式碼範例會開啟 X.509 憑證存儲、新增和刪除憑證，然後關閉存放區。 它假設您有三個要新增至本機存放區並從中移除的憑證。

C#

        }

        }

        //Remove a range of certificates.
        store.RemoveRange (collection);
        X509Certificate2Collection storecollection3 = (X509Certificate2Collection)store.Certificates;
        Console.WriteLine ("{1}Store name: {0}", store.Name, Environment.NewLine);
        if (storecollection3.Count == 0)
        {
            Console.WriteLine ("Store contains no certificates.");
        }
        else
        {
            foreach (X509Certificate2 x509 in storecollection3)
            {
                Console.WriteLine ("certificate name: {0}", x509.Subject);
            }
        }

        //Close the store.
        store.Close ();
    }	
}

備註

ReadOnly、 ReadWrite 和 MaxAllowed 旗標互斥。 旗 OpenExistingOnly 標是唯一不需要授與許可權的 StorePermissionFlags.CreateStore 旗標。
