STLineFromText 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 STLineFromText ( _
    lineStringTaggedText As SqlChars, _
    srid As Integer _
) As SqlGeometry
用法
Dim lineStringTaggedText As SqlChars
Dim srid As Integer
Dim returnValue As SqlGeometry

returnValue = SqlGeometry.STLineFromText(lineStringTaggedText, _
    srid)

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

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

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

public static function STLineFromText(
    lineStringTaggedText : SqlChars, 
    srid : int
) : SqlGeometry

参数

  • srid
    类型：System. . :: . .Int32
    An int expression that represents the spatial reference ID (SRID) of the SqlGeometry LineString instance you wish to return.

返回值

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