SqlGeometry.STRelate-Methode
Determines whether the calling SqlGeometry is related to the specified SqlGeometry.
Namespace: Microsoft.SqlServer.Types
Assembly: Microsoft.SqlServer.Types (in Microsoft.SqlServer.Types.dll)
Syntax

member STRelate :

intersectionPatternMatrix:string -> SqlBoolean
public function STRelate(
other : SqlGeometry,
intersectionPatternMatrix : String
) : SqlBoolean
Parameter
- other
Typ: Microsoft.SqlServer.Types.SqlGeometry
Is another SqlGeometry instance to compare against the instance on which STRelate is invoked.
- intersectionPatternMatrix
Typ: 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.
Rückgabewert
Typ: 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.
Hinweise
This method always returns nullein NULL-Verweis (Nothing in 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.
