To get a querystring you can use the Request.Querystring property:

Request.Querystring("parameter1")

Actually in C# it would be:
```
//this takes request parameters only from the query string
Request.QueryString["parameter1"];


//this one works for bot - form and query string
Request["parameter1"];
```

In Page1.aspx

Response.Redirect("Page2.aspx?param1=Test");

In Page2.aspx

if (Request.QueryString["param1"] != null)
Response.Write("From Page1 param1 value=" + Request.QueryString["param1"]);

Thanks

lol, sometime by sitting with a VB.Net project at the moment can destroy the way of writing C#, or the syntax can in a hurry be written wrong ;)

To add something vaulable to this post, you can also use Request.Params["parameter1"]

In the first page

response.redirect("a.aspx?ids=1&val=100",true)

and in the second page that is a.aspx

a=Request.QueryString("ids")

b= Request.QueryString("val")

thanks for you all

I'm sorry... but I still can't understand...

how about this example of url : http://forums.asp.net/AddPost.aspx?PostID=1566979

I want to get "1566979"

is it correct →Request.Querystring("PostID")    and I can get 1566979

once I get postID (1566969) I'll replace the X as 1566979

        string strConn = "data Source=x.x.x.x;user=sa;password=1234;initial catalog=Member";
        string strSQL = "select Subject,nContent from pro_News where Member_no = "x" ";
        SqlConnection conn = new SqlConnection(strConn);
        SqlCommand cmd = new SqlCommand(strSQL,conn);
        cmd.CommandType = CommandType.Text;
        conn.Open();
        SqlDataReader dr = cmd.ExecuteReader();
        while (dr.Read())
        {
        Label1.Text= (dr["Name"].ToString());
        Label2.Text = (dr["Address"].ToString());
        }
        cmd.Dispose();
        conn.Close();
        conn.Dispose();

the first page is writted with VB by other people ( I can't modify it..)

if I did

a=Request.QueryString("ids")

b= Request.QueryString("val")

then I can get a=18 , b=100 is it correct??

if you have this link below

response.redirect("a.aspx?ids=1&val=100",true)

a=Request.QueryString("ids")

b= Request.QueryString("val")

a = 1

b = 100

hi, how do I know which should I put it in response.redirect( )?

I have 2 page now ( a is writted by VB .. I can't modify it.. , b is writted by C#)

page a is shows many title... and once user click one of them it will direct to page b. page b will shows content which user click from page a..

so that's why I'm wondering .. is it ok? get parameter in url when we are in page b...
