[System::Runtime::CompilerServices::Extension]
static System::Data::Common::CommandTrees::DbFunctionExpression ^ SpatialRelate(System::Data::Common::CommandTrees::DbExpression ^ geometryValue1, System::Data::Common::CommandTrees::DbExpression ^ geometryValue2, System::Data::Common::CommandTrees::DbExpression ^ intersectionPatternMatrix);
public static System.Data.Common.CommandTrees.DbFunctionExpression SpatialRelate (this System.Data.Common.CommandTrees.DbExpression geometryValue1, System.Data.Common.CommandTrees.DbExpression geometryValue2, System.Data.Common.CommandTrees.DbExpression intersectionPatternMatrix);

<Extension()>
Public Function SpatialRelate (geometryValue1 As DbExpression, geometryValue2 As DbExpression, intersectionPatternMatrix As DbExpression) As DbFunctionExpression
Parameters
- geometryValue1
- DbExpression
An expression that specifies the first geometry value.
- geometryValue2
- DbExpression
An expression that specifies the geometry value that should be compared with geometryValue1
.
- intersectionPatternMatrix
- DbExpression
An expression that specifies the text representation of the Dimensionally Extended Nine-Intersection Model (DE-9IM) intersection pattern used to compare geometryValue1
and geometryValue2
.
Returns
A new DbFunctionExpression that returns a Boolean value indicating whether geometryValue1
is spatially related to geometryValue2
according to the spatial relationship designated by intersectionPatternMatrix
.
Exceptions
geometryValue1
geometryValue2
intersectionPatternMatrix
geometryValue1
geometryValue2
intersectionPatternMatrix
