此 API 支持 SQL Server 2012 基础结构,但不能通过代码直接使用。
Represents a union from a set of SqlGeometry objects.
继承层次结构

语法
声明

<SqlUserDefinedAggregateAttribute(Format.UserDefined, IsInvariantToDuplicates := True, _
IsInvariantToNulls := True, IsInvariantToOrder := True, _
IsNullIfEmpty := False, MaxByteSize := )> _
Public Class GeometryUnionAggregate _
Implements IBinarySerialize
