Response.Redirect如何传递2个参数到另外一个页面

[tanghp3]

在A页面 Response.Redirect("~/A.aspx?id&ds=" + ddl1.SelectedValue + ddl2.SelectedValue);
B页面string sqlstr2 = "SELECT * from t_city ";
sqlstr2 += "where id&ds" + Request.QueryString["id&ds"]; 请问如何才能在A页面把2个dropdownlist的值ddl1，ddl2传到B页面作为查询条件。我的格式错误，麻烦各位帮我改一下，谢谢

[我姓区不姓区]

Response.Redirect("~/A.aspx?id="+ddl1.SelectedValue+"&ds="+ddl2.SelectedValue);


string sqlstr2="select * from t_City where id="+Request.QueryString["id"]+" and ds = "+Request.QueryString["ds"];

[liujiayu10]

Response.Redirect("~/A.aspx?id=" + ddl1.SelectedValue +"&ds="+ ddl2.SelectedValue); 

B页面string sqlstr2 = "SELECT * from t_city "; 
sqlstr2 += "where id=" + Request.QueryString["id"].ToString()+" and ds = "+Request.QueryString["ds"].ToString(); 

建议兄弟先了解一下什么是URL参数

[bingy108]

同意LS两位的写法，lz你写 id&ds= + ddl1.SelectedValue + ddl2.SelectedValue

这个只是给ds赋值了，id没有值，&是一个连接符，正确来写应该是id=XXX&ds=XX ，然后再用

Request.QueryString["id"]和Request.QueryString["ds"]就能得到id的值XXX和ds的值XX。

Response.Redirect("~/A.aspx?id=" + ddl1.SelectedValue +"&ds="+ ddl2.SelectedValue);
sqlstr2 += "where id=" + Request.QueryString["id"].string() and ds = "+Request.QueryString["ds"].ToString(); ;
</fieldset>

[Quote=引用 1 楼 ojlovecd 的回复:]
Response.Redirect("~/A.aspx?id="+ddl1.SelectedValue+"&ds="+ddl2.SelectedValue);


string sqlstr2="select * from t_City where id="+Request.QueryString["id"]+" and ds = "+Request.QueryString["ds"];
[/Quote]

正确

[新时代新目标新征程]

Response.Redirect("~/A.aspx?id=" + ddl1.SelectedValue +"&ds="+ ddl2.SelectedValue);

B页面string sqlstr2 = "SELECT * from t_city ";
sqlstr2 += "where id=" + Request.QueryString["id"].ToString()+" and ds = "+Request.QueryString["ds"].ToString();
很明了了
