SpatialEdmFunctions.SpatialSymmetricDifference Method (DbExpression, DbExpression)
Creates a DbFunctionExpression that invokes the canonical 'SpatialSymmetricDifference' function with the specified arguments, which must each have an Edm.Geography or Edm.Geometry result type. The result type of spatialValue1 must match the result type of spatialValue2. The result type of the expression is the same as the type of spatialValue1 and spatialValue2.
Assembly: EntityFramework (in EntityFramework.dll)
public static DbFunctionExpression SpatialSymmetricDifference( this DbExpression spatialValue1, DbExpression spatialValue2 )
Parameters
- spatialValue1
-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that specifies the first spatial value.
- spatialValue2
-
Type:
System.Data.Entity.Core.Common.CommandTrees.DbExpression
An expression that specifies the spatial value for which the symmetric difference with spatialValue1 should be computed.
Return Value
Type: System.Data.Entity.Core.Common.CommandTrees.DbFunctionExpressionA new DbFunctionExpression that returns the geometry value representing the symmetric difference of spatialValue2 with spatialValue1.
