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


The following example uses STMPolyFromText() to create a geometry instance.

DECLARE @g geometry;  
SET @g = geometry::STMPolyFromText('MULTIPOLYGON (((5 5, 10 5, 10 10, 5 5)), ((10 10, 100 10, 200 200, 30 30, 10 10)))', 0);  
SELECT @g.ToString();
