一个类似百度的搜索。。。。。

protected void ImageButton1_Click(object sender, ImageClickEventArgs e)//搜索
{
Panel1.Visible = false;

DateTime t = DateTime.Now;
double d = 0;
int n=0;
string[] ss = new string[] {"oname","tel","address","pay","omoney","number","otime","remark"};
string condition = TextBox1.Text.Trim();
if (condition == "")
return;

DataTable dtb = new DataTable();

for (int i = 0; i < ss.Length; i++)
{
if (ss[i] == "otime" && DateTime.TryParse(condition,out t) == false)//如果查到时间时，如果时间不合法就跳出循环
continue;
if (ss[i] == "pay" && double.TryParse(condition, out d) == false)
continue;
if (ss[i] == "omoney" && double.TryParse(condition, out d) == false)
continue;
if (ss[i] == "number" && int.TryParse(condition, out n) == false)
continue;

cmdstr = "select * from [order],product where [order].pid=product.pid and "+ss[i]+=@0;
dt = new DataSet();
h = new sqlhelp(cmdstr, database, out adapter, condition);
adapter.Fill(dt);
if (dt.Tables[0].Rows.Count != 0)//如果有数据就不进行下一步操作
{
dtb.Merge(dt.Tables[0]);
}
}

DataList1.DataSource = dtb;
DataList1.DataKeyField = "oid";
DataList1.DataBind();

}
