推荐答案

要附加到现有的Excel文件，找到最后一排，用1加一

To append to an existing excel file, find the last row and increment it by 1

int _lastRow = xlWorkSheet.Cells.Find(
                              "*",
                              xlWorkSheet.Cells[1,1],
                              Excel.XlFindLookIn.xlFormulas,
                              Excel.XlLookAt.xlPart,
                              Excel.XlSearchOrder.xlByRows,
                              Excel.XlSearchDirection.xlPrevious,
                              misValue,
                              misValue,
                              misValue
                              ).Row + 1;

，然后简单地写入到该行

and then simply write to that row
