Question

hi there masters of c# code
i bow to your hard work and knowledge
i am a beginner and i would be very gratefull for full explainations and not just code snippets
my target is to create a web browser app in c# which load a difffrent website on each runtime
the string i want to run is posted below
i have about 70 webistes i wish the app to load a diffrent one from the 70 each runtime
the other thing is i want a way to make it load a diffrent user agent also each time i have also a list of about 120 user agents
thank you very much
i will post how far i got below
namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
webBrowser1.Navigate( http://www.anyweb.com , "_self", null, "User-Agent: Mozilla/4.0");
}
}

It looks to me like you've more or less done it already though I don't really see why you need a Dictionary for the user agents - I'd use a List for them as well.
Here's a more integrated version:
namespace WindowsFormsApplication2 {     public partial class Form1 : Form     {         List urls;         List userAgents;         static Random random;           public Form1()         {             InitializeComponent();             LoadWebsiteUrls();             LoadUserAgents();             random = new Random();                         string url = urls[random.Next(urls.Count)];             string user = userAgents[random.Next(userAgents.Count)];             webBrowser1.Navigate(url, "_self", null, user);          }
public void LoadWebsiteUrls()         {             urls = new List ();             urls.Add("http://a.b.c");             urls.Add("http://a.c.c");             //....         }
public void LoadUserAgents()         {             userAgents = new List ();             userAgents.Add("User-Agent: Mozilla/4.0");             userAgents.Add("User-Agent: Chrome/14.0");             // ....         }
} }

Note that " finally " implies no one else was able to help. I would have helped more but Vulpes replied before I was able to. I have other work to do also.
If it were me, I would help you to understand better how to solve the problem yourself. I wil try to remember to get back to this later; I have other things to do now.
One thing I wanted to point out is that you were doing a very common beginner mistake. Your code was creating a new Random class many tines. Look at Vulpes's code; he creates the Random class only once.

ok the data will be static hard coded
also i got soem more examples from some other coders
i will post here  if you guys can help me arrange into working code would be super
[code]
public List GetWebsiteUrls()
{
List urls = new List ();
url.Add(" http://a.b.c ");
url.Add(" http://a.c.c ");
....
return urls;
}
namespace WindowsFormsApplication2
{
public partial class Form1 : Form
{
static List urls;
static Random random;
public Form1()
{
InitializeComponent();
if(urls ==  null)
{
urls = GetWebsiteUrls();  //Need to implement
random = new Random();
}
string url = urls[random.Next(urls.count)];
webBrowser1.Navigate(url, "_self", null, "User-Agent: Mozilla/4.0
}
}
}
Dictionary userAgent = new Dictionary (); userAgent.Add(0, "User-Agent: Mozilla/4.0");
userAgent.Add(0, "User-Agent: Chrome/14.0");
string user = userAgent[random.Next(userAgent.Count)];
webBrowser1.Navigate(url, "_self", null, user);
[/code]

Welcome to C# Corner.
Note that your question is actually two or more questions.
How to generate a random number in the range of the number of selections How to retrieve the selection corresponding to the number generated
You can use the Random class in .Net to generate a random number. I have not used it myself but there are very many articles that describe its use.
Since you do not specify how the data is stored, it is difficult to suggest how to access it in a way that will help you.
