SpatialEdmFunctions.SpatialRelate Method (DbExpression, DbExpression, DbExpression)
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.
Assembly: EntityFramework (in EntityFramework.dll)
public static DbFunctionExpression SpatialRelate( this DbExpression geometryValue1, DbExpression geometryValue2, DbExpression intersectionPatternMatrix )
Parameters
- geometryValue1
-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that specifies the first geometry value.
- geometryValue2
-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that specifies the geometry value that should be compared with geometryValue1.
- intersectionPatternMatrix
-
Type:
System.Data.Entity.Core.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.Entity.Core.Common.CommandTrees.DbFunctionExpressionA new DbFunctionExpression that returns a Boolean value indicating whether geometryValue1 is spatially related to geometryValue2 according to the spatial relationship designated by intersectionPatternMatrix.
