STPointFromText 方法

Returns a SqlGeometry instance from an Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation augmented with any Z (elevation) and M (measure) values carried by the 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 Shared Function STPointFromText ( _
    pointTaggedText As SqlChars, _
    srid As Integer _
) As SqlGeometry
用法
Dim pointTaggedText As SqlChars
Dim srid As Integer
Dim returnValue As SqlGeometry

returnValue = SqlGeometry.STPointFromText(pointTaggedText, _
    srid)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public static SqlGeometry STPointFromText(
    SqlChars pointTaggedText,
    int srid
)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
static SqlGeometry^ STPointFromText(
    SqlChars^ pointTaggedText, 
    int srid
)

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
static member STPointFromText : 
        pointTaggedText:SqlChars * 
        srid:int -> SqlGeometry 

public static function STPointFromText(
    pointTaggedText : SqlChars, 
    srid : int
) : SqlGeometry

参数

返回值

类型：Microsoft.SqlServer.Types. . :: . .SqlGeometry
A SqlGeometry instance constructed from the specified WKT representation.
