Параметры

  • intersectionPatternMatrix
    Тип: System. . :: . .String
    A string that specifies the intersection model. This string must contain acceptable values for the DE-9IM pattern matrix device between the two SqlGeometry instances.

Возвращаемое значение

Тип: System.Data.SqlTypes. . :: . .SqlBoolean
Returns true if a SqlGeometry instance is related to another SqlGeometry instance, where the relationship is defined by a Dimensionally Extended 9 Intersection Model (DE-9IM) pattern matrix value; otherwise, returns false.

Замечания

This method always returns null Nothing nullptr unit пустая ссылка (Nothing в Visual Basic) if the spatial reference IDs (SRIDs) of the SqlGeometry instances do not match. This method will throw an ArgumentException if the matrix is not well-formed.
