<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

DbFunctionExpression

A new DbFunctionExpression that returns a Boolean value indicating whether geometryValue1 is spatially related to geometryValue2 according to the spatial relationship designated by intersectionPatternMatrix.
