ofd.InitialDirectory = "c:\\";
ofd.RestoreDirectory = true;
ofd.FilterIndex = 1;
ofd.AddExtension = true;
ofd.CheckFileExists = true;
ofd.CheckPathExists = true;
ofd.ShowHelp = true; //是否显示帮助按钮

if (ofd.ShowDialog() == DialogResult.OK)
{
size_editfalge = "0";
thinkss_editflage = "0";
door_editflage = "0";
filePath = ofd.FileName;

Workbook workbook = new Workbook();

workbook.Open(filePath);

for (int i = 0; i < workbook.Worksheets.Count; i++)
{
//取第一个表
Cells cells = workbook.Worksheets[i].Cells;
if (cells.MaxDataRow != 0)
{
dt = cells.ExportDataTable(1, 0, cells.MaxDataRow, 导入EXCEL的列数);
dt =dt_handle(dt);
//获取到了数据，存储到表中

bool k = insert_into_db(dt);
