HTuple HObject使用记录

从HTuple获取数据

HTuple hTuple= hDevelopExport.hv__Row1;

double RR = hTuple[0].D;

            double[] ret = hTuple.ToDArr(); 
            double[] ret1 = hTuple1.ToDArr();
            double testD = hTuple[0].D;
            //string testS = hTuple[0].S;
            long testL = hTuple[0].L;
            int testI = hTuple[0].I;
            Object testO = hTuple[0].O;
            float testF = hTuple[0].F;

给HTuple赋值

HTuple data = new HTuple(ret);
