1>獲取監測站點的名稱
var s = datagridview1[1, i].value.tostring();
2>根據監測站點名稱得到編號
string stationcode = getstationcodeorpoll(datagridview1[1, i].value.tostring());
getstationcodeorpoll()方法
private string getstationcodeorpoll(string code)
return null;
}3>獲取級別
var level = datagridview1[12, i].value.tostring();
