SqlGeography.STGeomFromText Method
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.

Parameters
- geometryTaggedText
Type: System.Data.SqlTypes.SqlChars
The WKT representation of the SqlGeography instance you wish to return.
- srid
Type: System.Int32
An int expression that represents the spatial reference ID (SRID) of the SqlGeography instance you wish to return.
Return Value
Type: Microsoft.SqlServer.Types.SqlGeography
A SqlGeography instance constructed from the WKY representation.
Remarks
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.
