STConvexHull 方法

Returns an object that represents the convex hull of a SqlGeometry instance.

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 SqlGeometry
用法
Dim instance As SqlGeometry
Dim returnValue As SqlGeometry

returnValue = instance.STConvexHull()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlGeometry STConvexHull()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlGeometry^ STConvexHull()

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STConvexHull : unit -> SqlGeometry 

public function STConvexHull() : SqlGeometry

返回值

类型：Microsoft.SqlServer.Types. . :: . .SqlGeometry
A SqlGeometry value that represents the convex hull of the calling SqlGeometry.

注释

STConvexHull returns the smallest convex polygon that contains the given SqlGeometry instance. Points or co-linear LineString instances will produce an instance of the same type as that of the input.
