STNumPoints 方法

Returns the total number of points in each of the figures in a SqlGeography 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 := True)> _
Public Function STNumPoints As SqlInt32
用法
Dim instance As SqlGeography
Dim returnValue As SqlInt32

returnValue = instance.STNumPoints()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public SqlInt32 STNumPoints()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)]
public:
SqlInt32 STNumPoints()

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = true)>]
member STNumPoints : unit -> SqlInt32 

public function STNumPoints() : SqlInt32

返回值

类型：System.Data.SqlTypes. . :: . .SqlInt32
A SqlInt32 value specifying the total number of points in each figure of the SqlGeography instance.

注释

This method counts the points in the description of a SqlGeography instance. Duplicate points are counted. If this instance is a GeometryCollection, this method returns of the total number of points in each of the elements in the collection.
