List 排序功能实现

    public class ClippedRasterComparer : IComparer<ClippedRaster>
    {
        public int Compare(ClippedRaster clr1, ClippedRaster clr2)
        {
            //return clr1._absoluteVolume.CompareTo(clr2._absoluteVolume);//升序
            return clr2._absoluteVolume.CompareTo(clr1._absoluteVolume);//降序
        }
    }

//定义类ClippedRasterComparer,在类中实现排序接口。

 ICompare<> 尖括号内的写用于排序的对象类型。可以写List<>的元素类型

         //按_absoluteVolume升序排列
            ClippedRasterComparer crp=new ClippedRasterComparer();
            li_intersectedRasters.Sort(crp);
