通过

STNumGeometries 方法

Returns the number of geometries that make up 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 STNumGeometries As SqlInt32
用法
Dim instance As SqlGeography
Dim returnValue As SqlInt32

returnValue = instance.STNumGeometries()

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

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

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

public function STNumGeometries() : SqlInt32

返回值

类型：System.Data.SqlTypes. . :: . .SqlInt32
A SqlInt32 value that specifies the number of geometries that make up the SqlGeography instance.

注释

This method returns 1 if the geography instance is not a MultiPoint, MultiLineString, MultiPolygon, or GeometryCollection instance, or 0 if the SqlGeography instance is empty.
