UserDefinedAggregateParameterCollection 类型公开以下成员。

属性

  名称 说明
公共属性 Count Gets the number of objects in the referenced collection. (从 SmoCollectionBase 继承。)
公共属性 IsSynchronized Gets the Boolean property value that specifies whether access to the collection is synchronized and therefore thread-safe. (从 SmoCollectionBase 继承。)
公共属性 Item[Int32] Gets a UserDefinedAggregateParameter object in the collection by index number.
公共属性 Item[String] Gets a UserDefinedAggregateParameter object in the collection by name.
公共属性 Parent Gets the UserDefinedAggregate object that is the parent of the UserDefinedAggregateParameter object.
公共属性 SyncRoot Gets an object that can be used to synchronize access to the collection. (从 SmoCollectionBase 继承。)

注释

A UserDefinedAggregateParameterCollection object can be used to gain access to a set of user-defined aggregate parameters. You can use the Item property to return a specific UserDefinedAggregateParameter object.
