public static DbFunctionExpression SpatialConvexHull(
	this DbExpression geometryValue
)

Parameters

geometryValue
Type: System.Data.Entity.Core.Common.CommandTrees.DbExpression

An expression that specifies the geometry value from which the convex hull value should be retrieved.

Return Value

Type: System.Data.Entity.Core.Common.CommandTrees.DbFunctionExpression

A new DbFunctionExpression that returns the the convex hull for geometryValue.
