Remarks

在配置文件中,配置节包含特性和元素。In a configuration file, a configuration section contains both attributes and elements. 配置节的锁定特性存在 ConfigurationLockCollection 集合,并通过 ConfigurationElement 类的 LockAttributes 属性进行访问。A ConfigurationLockCollection collection exists for the locked attributes of a configuration section, and is accessed through the LockAttributes property of the ConfigurationElement class. 配置节的锁定元素存在另一个 ConfigurationLockCollection 集合,可通过 ConfigurationElement 类的 LockElements 属性进行访问。Another ConfigurationLockCollection collection exists for the locked elements of a configuration section, and is accessed through the LockElements property of the ConfigurationElement class.

Properties
