Método STRelate

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

Namespace:  Microsoft.SqlServer.Types
Assembly:  Microsoft.SqlServer.Types (em Microsoft.SqlServer.Types.dll)

Sintaxe

'Declaração
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := False)> _
Public Function STRelate ( _
    other As SqlGeometry, _
    intersectionPatternMatrix As String _
) As SqlBoolean
'Uso
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

Parâmetros

  • intersectionPatternMatrix
    Tipo: 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.

Valor de retorno

Tipo: 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.

Comentários

This method always returns null Nothing nullptr unit uma referência nula (Nothing no 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.
