给分三十分,急呀!用户代码未处理 System.IndexOutOfRangeException Message="在位置 0 处没有任何行。"

public partial class Default2 : System.Web.UI.Page
{
string gid;
DataTable dtTable;
Hashtable hashCar;
string strSql;
WebService webService = new WebService();
protected void Page_Load(object sender, EventArgs e)
{
if (Request.QueryString["gid"] != null)
strSql = "Update z_GoodsInfo set Goods_point=Goods_point+1 where Goods_ID='" + gid + "'";
webService.ExcuteSql(strSql);//保存到数据库中
strSql = "select * from z_GoodsInfo where Goods_ID='" + gid + " '";
dtTable = webService.ExcuteSelect(strSql);
this.lblGoodsName.Text = dtTable.Rows[0]["Goods_name"].ToString(); this.lblDesc.Text = dtTable.Rows[0]["Goods_orderDesc"].ToString();
this.Image1.ImageUrl = dtTable.Rows[0]["Goods_img"].ToString();
this.lblPoint.Text = dtTable.Rows[0]["Goods_point"].ToString();
this.lblAddDate.Text = dtTable.Rows[0]["Goods_addDate"].ToString();
this.lblGoodsMsg.Text = dtTable.Rows[0]["Goods_introduce"].ToString();
if (dtTable.Rows[0]["Goods_isSpecial"].ToString() == "y")
this.lblPrice.Text = "优惠价：$" + dtTable.Rows[0]["Goods_specialPrice"].ToString();
else
this.lblPrice.Text = "$" + dtTable.Rows[0]["Goods_price"].ToString();
this.lbtnBuy.CommandArgument = gid;
错误信息是:并用特殊颜色标注,用户代码未处理 System.IndexOutOfRangeException

先确定DataTable里有没有数据。看看DataTable.Rows.Count的值

DataTable.Rows.Count>0就绑定，否则提示
