SpatialEdmFunctions.SpatialRelate Method (DbExpression, DbExpression, DbExpression)

.NET Framework (current version)
 

Creates a DbFunctionExpression that invokes the canonical 'SpatialRelate' function with the specified arguments, which must have Edm.Geometry and string result types. The result type of the expression is Edm.Boolean.

Namespace:   System.Data.Common.CommandTrees.ExpressionBuilder.Spatial
Assembly:  System.Data.Entity (in System.Data.Entity.dll)

public static DbFunctionExpression SpatialRelate(
	this DbExpression geometryValue1,
	DbExpression geometryValue2,
	DbExpression intersectionPatternMatrix
)

Parameters

geometryValue1
Type: System.Data.Common.CommandTrees.DbExpression

An expression that specifies the first geometry value.

geometryValue2
Type: System.Data.Common.CommandTrees.DbExpression

An expression that specifies the geometry value that should be compared with geometryValue1.

intersectionPatternMatrix
Type: System.Data.Common.CommandTrees.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.

Return Value

Type: System.Data.Common.CommandTrees.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.
