命名空间： Microsoft.SqlServer.Types
程序集： Microsoft.SqlServer.Types（在 Microsoft.SqlServer.Types.dll 中）
语法
声明
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := False)> _
Public Function STConvexHull As SqlGeography
用法
Dim instance As SqlGeography
Dim returnValue As SqlGeography
returnValue = instance.STConvexHull()
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlGeography STConvexHull()
[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlGeography^ STConvexHull()
[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STConvexHull : unit -> SqlGeography
public function STConvexHull() : SqlGeography
返回值
类型：Microsoft.SqlServer.Types.SqlGeography
The convex hull.
