注解
Web 部件区域中的控件可以作为另一个控件中的数据的使用者，或者充当其他控件的数据提供者。A control in a Web Parts zone can act as a consumer of data from another control or as a provider of data to other controls. 此类表示这些连接的集合。This class represents a collection of those connections. 通常，此类的实例是从属性（如或）返回 Connections 的 StaticConnections 。Typically, an instance of this class is returned from a property such as Connections or StaticConnections. 您可以用与任何集合相同的方式循环访问集合，并且可以使用属性搜索特定的连接 ID 。You can iterate through the collection in the same way you would any collection, and you can search for a particular connection using the ID property.
