random genereration in ASP.NET---
<p>My following code generates two different values but I need same value to be posted for an event.</p>

<pre><code>    protected void Button1_Click(object sender, EventArgs e)
{
    try
    {
        string url = "transfer.aspx";
        string rgen = randomurl.passwordString();
        string gpeck = rgen;
        Response.Redirect(url + "?msession=" + gpeck);
        Session["sendval"] = gpeck;
    }


       catch
        {

        } 
  }
</code></pre>

<hr>

<pre><code>class file :

public class randomurl
{
    public static string passwordString()
    {
        string allowedChars = "";
        allowedChars = "a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z,";
        allowedChars += "A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P,Q,R,S,T,U,V,W,X,Y,Z,";
        allowedChars += "1,2,3,4,5,6,7,8,9,0";
        char[] sep = { ',' };
        string[] arr = allowedChars.Split(sep);
        string passwordString = "";
        string temp = "";
        Random rand = new Random();
        for (int i = 0; i &lt; Convert.ToInt32(64); i++)
        {
            temp = arr[rand.Next(0, arr.Length)];
            passwordString += temp;
        }
        return passwordString;
    }
}
