STGeomFromText 方法

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 STGeomFromText ( _
    geometryTaggedText As SqlChars, _
    srid As Integer _
) As SqlGeography
用法
Dim geometryTaggedText As SqlChars
Dim srid As Integer
Dim returnValue As SqlGeography

returnValue = SqlGeography.STGeomFromText(geometryTaggedText, _
    srid)

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

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

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

public static function STGeomFromText(
    geometryTaggedText : SqlChars, 
    srid : int
) : SqlGeography

参数

返回值

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

注释

The OGC type of the SqlGeography instance returned by STGeomFromText is set to the corresponding WKT input.

This method will throw a FormatException if the input is not well-formatted.
