STRelate 方法

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

命名空间：  Microsoft.SqlServer.Types
程序集：  Microsoft.SqlServer.Types（在 Microsoft.SqlServer.Types.dll 中）

语法

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

参数

  • intersectionPatternMatrix
    类型：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.

返回值

类型：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.

注释

This method always returns null Nothing nullptr unit null 引用（在 Visual Basic 中为 Nothing） 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.
