c#怎么往已存在的excel添加数据

Answer 1

添加excel类库引用
//加载excel
Application app = new Application();
Workbooks wb = app.Workbooks;
_Workbook _wb = wb.Add("excel路径");
//获取sheet
Sheets sh = _wb.Sheets;
_Worksheet _wsh = (_Worksheet)sh.get_Item(1);
_wsh.Cells[3, 2] = person.Name;//3为excel行，2为excel列
_wsh.SaveAs("填写完成后要保存的路径",
Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);

_wb.Close();
wb.Close();
