Returns a SqlGeography 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 STMLineFromText ( _
    multiLineStringTaggedText As SqlChars, _
    srid As Integer _
) As SqlGeography
用法
Dim multiLineStringTaggedText As SqlChars
Dim srid As Integer
Dim returnValue As SqlGeography

returnValue = SqlGeography.STMLineFromText(multiLineStringTaggedText, _
    srid)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public static SqlGeography STMLineFromText(
    SqlChars multiLineStringTaggedText,
    int srid
)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
static SqlGeography^ STMLineFromText(
    SqlChars^ multiLineStringTaggedText, 
    int srid
)

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
static member STMLineFromText : 
        multiLineStringTaggedText:SqlChars * 
        srid:int -> SqlGeography 

public static function STMLineFromText(
    multiLineStringTaggedText : SqlChars, 
    srid : int
) : SqlGeography

参数

  • srid
    类型：System. . :: . .Int32
    An integer expression representing the Spatial Reference ID (SRID) of the SqlGeographyMultiLineString instance you wish to return.

返回值

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