Méthode STRelate

Determines whether the calling SqlGeometry is related to the specified SqlGeometry.

Espace de noms :  Microsoft.SqlServer.Types
Assembly :  Microsoft.SqlServer.Types (en Microsoft.SqlServer.Types.dll)

Syntaxe

'Déclaration
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := False)> _
Public Function STRelate ( _
    other As SqlGeometry, _
    intersectionPatternMatrix As String _
) As SqlBoolean
'Utilisation
Dim instance As SqlGeometry
Dim other As SqlGeometry
Dim intersectionPatternMatrix As String
Dim returnValue As SqlBoolean

returnValue = instance.STRelate(other, _
    intersectionPatternMatrix)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public SqlBoolean STRelate(
    SqlGeometry other,
    string intersectionPatternMatrix
)

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
SqlBoolean STRelate(
    SqlGeometry^ other, 
    String^ intersectionPatternMatrix
)

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
member STRelate : 
        other:SqlGeometry * 
        intersectionPatternMatrix:string -> SqlBoolean 

public function STRelate(
    other : SqlGeometry, 
    intersectionPatternMatrix : String
) : SqlBoolean

Paramètres

  • intersectionPatternMatrix
    Type : 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.

Valeur de retour

Type : 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.

Notes

This method always returns null Nothing nullptr unit une référence Null (Nothing dans 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.
