매개 변수

  • geometryType
    유형: System.String
    A string that specifies one of the 12 types exposed in the geography type hierarchy.

반환 값

유형: System.Data.SqlTypes.SqlBoolean
A SqlBoolean value that indicates whether the SqlGeography instance is the same as the specified geometry type.Returns true if the type of a geography instance is the same as the specified type, or if the specified type is an ancestor of the instance type; otherwise, returns false.


The input for the method must be one of the following: T:Microsoft.SqlServer.Types.SqlGeometry, Point, Curve, LineString, Surface, Polygon, GeometryCollection, MultiSurface, MultiPolygon, MultiCurve, MultiLineString, and MultiPoint.

This method throws an ArgumentException if any other strings are used for the input.
