ConnectionOptions 构造函数

定义

创建新的 ConnectionOption。

重载

ConnectionOptions()

使用默认值,为连接操作初始化 ConnectionOptions 类的新实例。 这是无参数构造函数。

ConnectionOptions(String, String, SecureString, String, ImpersonationLevel, AuthenticationLevel, Boolean, ManagementNamedValueCollection, TimeSpan)

创建新的 ConnectionOption。

ConnectionOptions(String, String, String, String, ImpersonationLevel, AuthenticationLevel, Boolean, ManagementNamedValueCollection, TimeSpan)

使用指定的值,初始化将用于 WMI 连接的 ConnectionOptions 类的新实例。
