- 坐标列表去重：基于List的Distinct方法去重
public class PointLatLngComparer : IEqualityComparer<PointLatLng>{public bool Equals(PointLatLng x, PointLatLng y){return x.Lat == y.Lat && x.Lng == y.Lng;}public int GetHashCode(PointLatLng obj){return string.Format("{0},{1}", obj.Lng, obj.Lat).GetHashCode();}}
//controlPoints 是List<PointLatLng>的变量，坐标去重
controlPoints = controlPoints.Distinct(new PointLatLngComparer()).ToList();
