c# - How do we programatically add data from datagrid to list? -

-

i have following code, list not fetching exact values datagrid. 

public list<double[]> extractgriddata(datagridview grid)     {         int numcols = grid.columns.count;         list<double[]> list = new list<double[]>();              double[] cellsdata = new double[numcols];             foreach (datagridviewcell cell in grid.selectedcells)             {                 if (cell.value != null)                     cellsdata[cell.rowindex] = convert.todouble(cell.value);                     list.add(cellsdata);             }          return list;     }

i think need move:

double[] cellsdata = new double[numcols];

to within start of loop. @ moment, using same instance of array every iteration.
