I want to generate a number and I want it appear on a asp:label. Also the number have to be between 1 to 99 (min. - max.)

That number will be added to a number generated in a captcha. I know how to generate a catpcha and added a number but not a ramdom one.

I hope that solution stop spambots

Code:

Random rand = new Random();
    
mylabel.Text = rand.Next(1,99).ToString();

this is probably the easiest way.

That will return the same number every page load, I think. I had implemented the same concept but it is returning the same numbers.

Code:

        Random r = new Random(1);
        int ans,n1,n2;
        n1 = r.Next(1,4);
        n1 = r.Next(1, 4);
        n1 = r.Next(1, 4);
        n2 = r.Next(4, 8);
        n2 = r.Next(4, 8);
        n2 = r.Next(4, 8);
        ans = n1 + n2;
        Label5.Text = "Please Answer: " + n1.ToString() + " + " + n2.ToString() + " = ";

No it wont.

You are correct that it's not random in the truest sense but it'll display a different number for each page load.
