參數
- wkbGeometry
型別：System.Data.SqlTypes.SqlBytes
The WKB representation of the SqlGeography instance you wish to return.
- srid
型別：System.Int32
An int expression that represents the Spatial Reference ID (SRID) of the SqlGeography instance you wish to return.
傳回值
型別：Microsoft.SqlServer.Types.SqlGeography
A SqlGeography instance constructed from the specified WKB representation.
備註
The OGC type of the SqlGeography instance returned by the STGeomFromText method is set to the corresponding WKB input.
This method throws a FormatException if the input is not well-formatted.
