指定打开 X.509 证书存储的方法。
此枚举支持其成员值的按位组合。

IncludeArchived | 8 | 打开 X.509 证书存储区并添加存档证书。 |
MaxAllowed | 2 | 以允许最高级访问的方式打开 X.509 证书存储区。 |
OpenExistingOnly | 4 | 仅打开现有存储区。如果不存在任何存储区,Open(OpenFlags) 方法不会创建新的存储区。 |
ReadOnly | 0 | 以只读方式打开 X.509 证书存储区。 |
ReadWrite | 1 | 以读写方式打开 X.509 证书存储区。 |
示例
下面的代码示例打开一个 X.509 证书存储,添加和删除证书,然后关闭该存储区。 它假定要向本地存储添加和删除三个证书。
