```

## Return Types

## Remarks

This method counts the points in the description of a **geometry** instance. Duplicate points are counted. If this instance is a **collection** type, this method returns the sum of the points in each of its elements.

## Examples

instance and uses `STNumPoints()`

to determine how many points were used in the description of the instance.

```
DECLARE @g geometry;
SET @g = geometry::STGeomFromText('LINESTRING(0 0, 2 2, 1 0)', 0);
SELECT @g.STNumPoints();
```
