how to use switch statement to navigate between url c#

Abbas Hamza

i have this method which will take 1 url :

public static void LaunchSite(Uri sitUrl)
{
SHDocVw.ShellWindows w = new SHDocVw.ShellWindows();
bool found = false;
foreach (SHDocVw.ShellBrowserWindow item in w)
{
var doc = item.LocationURL;
if (!string.IsNullOrEmpty(doc))
if (doc == sitUrl.AbsoluteUri)
{
found = true;
break;
}
}
if (!found)
Process.Start(sitUrl.AbsoluteUri);
}

button event handler looks like this

private void btnSubs_Click(object sender, RoutedEventArgs e)
{
//StartProcess.webSit();
Uri oxfArt = new Uri(@"http://www.oxfordartonline.com/subscriber/");
Uri theoryTst = new Uri("http://theorytestpro.co.uk/");
string webAddress = oxfArt.OriginalString;
switch (webAddress)
{
case "http://www.oxfordartonline.com/subscriber/":
StartProcess.LaunchSite(oxfArt);
break;
case "http://theorytestpro.co.uk/":
StartProcess.LaunchSite(theoryTst);
break;
default:
break;
}
}

the button event handler will handle multiple buttons so depending on which button clicked need to determine which Uri need to be launched using switch statement. thank you

You should be able to use:
Content="click" Tag="http://theorytestpro.co.uk/" Click="btnSubs_Click" />
And then use:

private void btnSubs_Click(object sender, RoutedEventArgs e)
{
   Button button = sender as Button;
   if (button != null)
   {
      Uri uri = new Uri((string)button.Tag);
      StartProcess.LaunchSite(uri);
   }
}

this what i have done:

Button btnSub = e.Source as Button;

switch (btnSub.Name)
{

case "oxfArt":
Uri uri = new Uri((string)btnSub.Tag);
StartProcess.LaunchSite(uri);
break;
case "theorytst":
Uri uri1 = new Uri((string)btnSub.Tag);
StartProcess.LaunchSite(uri1);
break;
default:
break;
}

it worked fine but i wonder if there is away if i can make the Uri variable global stopping the declaration in each case of the switch statement.
thank you

this look closer to what I'm looking for, but i can't get it to work as I'm using WPF and my button is declared in XAML every time i run your code the button is always = null: any ideas

Every Control has a Tag property. If you assign the URI to the Tag property of your buttons, then you don't even need the switch statement. Something like this:

button1.Tag =  new Uri("http://theorytestpro.co.uk/");
button2.Tag = new Uri("http://www.oxfordartonline.com/subscriber/");

And then in the click event (which they share):
   private void btnSubs_Click(object sender, RoutedEventArgs e)
{
     Button button = sender as Button;
     if (button != null)
     {
         Uri uri = button.Tag as Uri;
        if (uri != null)
        {
           StartProcess.LaunchSite(uri);
        }
      }
}
