'用途
Dim instance As SqlSpatialServices
Dim geometryValue As DbGeometry
Dim otherGeometry As DbGeometry
Dim returnValue As Boolean
returnValue = instance.Overlaps(geometryValue, _

otherGeometry:DbGeometry -> bool
public override function Overlaps(
geometryValue : DbGeometry,
otherGeometry : DbGeometry

參數
- geometryValue
類型：System.Data.Entity.Spatial.DbGeometry
第一個幾何值。
- otherGeometry
類型：System.Data.Entity.Spatial.DbGeometry
第二個幾何值。
傳回值
類型：System.Boolean
若 geometryValue 和 otherGeometry 重疊，則為 true，否則為 false。
