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

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

Parameter

  • 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.
