在相关位置的DataGridView中添加一个DataGridViewCheckBoxColumn.

在buttonCalucate_Click事件中..如下循环遍历所有行，并总计选定的行.

add a DataGridViewCheckBoxColumn to your DataGridView at relevant position.

in buttonCalucate_Click event.. loop through all the rows as follows and do total of the selected rows.

double dblTotal = 0.0;
foreach (DataGridViewRow row in dataGridView1.Rows)
{             
   DataGridViewCheckBoxColumn colObj = row.Cells[0] as DataGridViewCheckBoxColumn ;

   if (colObj.Selected)
   {
      dblTotal += convert.toDouble(row.Cells[1].Value.toString());
   }
}
