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

---|---|---|
Add(UserDefinedAggregateParameter) | Adds a UserDefinedAggregateParameter object to the UserDefinedAggregateParameterCollection object. | |
Add(UserDefinedAggregateParameter, Int32) | Adds a UserDefinedAggregateParameter object to the UserDefinedAggregateParameterCollection object at the specified position. | |
Add(UserDefinedAggregateParameter, String) | Adds a UserDefinedAggregateParameter object to the UserDefinedAggregateParameterCollection object at the specified position. | |
AddExisting | Adds an object to the collection. (从 AbstractCollectionBase 继承。) | |
Contains | Validates whether the parameter collection contains a member with a name equal to the specified string. (从 ParameterCollectionBase 继承。) | |
CopyTo | Copies the collection objects to a one-dimensional array starting at the specified index value. | |

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.
