The appears to be the Query String that you are sending to another page as part of the URL.  ASP .NET is able to process this string very easily using Request.QueryString
Let's use the example you inclued ("x=3&z=2&o=9") as the query string, so the URL would look something like
 http://myserver.mycompany.com/mypage.aspx?x=3&z=2&o=9
I have attached the code that would be used to process this query string.  This would most likely be done during the Page's Load event.
The code I have attached is in Visual Basic.

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
    myTextBoxx.Text=Request.QueryString("x")
    myTextBoxz.Text=Request.QueryString("z")
    myTextBoxo.Text=Request.QueryString("o")
EndSub

No I'm not sending a querystring.
I suggest everyone before responding to any question to read the auther's Knowledge level that provided with the question.
As you can see my knowledge level is intermediate, that means any intermediate ASP.NET developer should know how to process querystring.

string str = "x=3&z=2&o=9";

string []str1 = str.Split("&");

NameValueCollection nvc = new NameValueCollection();

foreach(STring str2 in str1)
{
        string[] st = str2.split("=");
         nvc.add(st[0],st[1]);
}

Sorry for the misunderstanding.  If I would have read your questiong a litt more thuroughly, I would probably have realized that this was not an actual URL query string.
I have attache a function that would treat this string as you mentioned as the Request.QueryString method would the URL querystring in a web page.  This function accepts the raw data as the first paramater and the variable desired as the second variable.
The function uses the String.Split method twice to parse out the & and the =.
I hope this helps.

Function myQueryString(ByVal qString As String, ByVal qVar As String) As String
        Dim i As Integer
        Dim ret As String = ""
        Dim sTemp() As String = qString.Split("&")
        For i = 0 To sTemp.Length - 1
            Dim varString() As String = sTemp(i).Split("=", 2, StringSplitOptions.None)
            If varString(0) = qVar Then
                ret = varString(1)
                Exit For
            End If
        Next
        Return ret
    End Function
