C#

Hello, I did a code which have an integer value in a block. I have passed this value to another block on button click event but I want to pass the same integer value to the 3rd block. I did this code :

void wc_DownloadStringCompleted1(object sender, DownloadStringCompletedEventArgs e)
{
    ...
    dynamic num = label1.Bottom + (i * 30);
    button1.Click += new EventHandler((sender1, e1) => button1_Click(sender, e, num);
}

I have passed this integer value to the following code :

void browsebutton_Click(object sender, DownloadStringCompletedEventArgs e, int num)
{
    ...
    wc.DownloadStringCompleted += wc_DownloadStringCompleted2;
//[In its place I also tried this : wc.DownloadStringCompleted +=new     //DownloadStringCompletedEventHandler((sndr, ev) => wc_DownloadStringCompleted2(sender, e, //num)); but when I used this the control is not going to the 3rd block]
}

Now I want to pass that num value to the following block

void wc_DownloadStringCompletedbrowse2(object sender, DownloadStringCompletedEventArgs e)
{
   ....
}

Please any one give me any suggestion.

Thanks.
