... //前一段先读出excel文件里面的内容


SqlDataAdapter sqlDA1 = new SqlDataAdapter(getCustomerInfo,sqlConnection1);
SqlCommandBuilder sqlCB1 = new SqlCommandBuilder(sqlDA1);
sqlDA1.Fill(dataTable1);
//上面三句先把原来的数据读出来


//设置一个循环 每次循环都新建一行
{
DataRow dataRow1 = dataTable1.NewRow();


... //一行一行地把excel里面的数据插入datatable


dataTable1.Rows.Add(dataRow1);
}//循环完毕

sqlDA1.Update(dataTable1); //插入数据库的关键
