int[,] numArr = new int[,] { { 4, 4 }, { 3, 3 }, { 5, 5 }, { 2, 2 }, { 1, 1 } }
根据第一个维度从大到小排序
如果是引用类型如何排序
//(DrawMapping) LatPos.X,LatPos.X
//(DrawMapping) service.GetMappingPosition(LatPos[] latArr); //方法重载
//(DrawMapping) service.GetMappingPosition(List<LatPos> latList); //方法重载
//(DrawMapping) service.GetMappingPosition(string[,] latStrArr); //方法重载
LatPos[] latArr=new LatPos[myPos.length];
latArr[0]=new LatPos(4,4);
latArr[1]=new LatPos(3,3);
latArr[2]=new LatPos(1,1);
latArr[3]=new LatPos(6,6);
latArr[4]=new LatPos(7,7);
通过Linq给以上数组排序根据位置的第一个参数从大到小
service.GetMappingPosition(LatPos[] latArr);
service.GetMappingPosition(List<LatPos> latList);
service.GetMappingPosition(string[,] latStrArr);
