參數
- s
型別：System.Data.SqlTypes.SqlString
The WKT representation of the SqlGeography instance you wish to return.
傳回值
型別：Microsoft.SqlServer.Types.SqlGeography
A SqlGeography value constructed from the specified WKT representation.
備註
The Parse method is equivalent to STGeomFromText except that it assumes a spatial reference ID (SRID) of 4326 as a parameter. The input may carry optional Z (elevation) and M (measure) values.
