How to check a key value in a if statment [on hold]

I'm trying to have a if statement look at the key vale and determine if it is IE.HTTP or not and if not to run the code that changes it to IE.HTTP

Im not quite sure on how to get it to read the key value, any sort of help would be much appreciated

namespace ChangeDefaultBrowser 
{ 

    class Program
    {
        static void Main()
        {
            string input; 

            using( RegistryKey myKey = Registry.CurrentUser.OpenSubKey(@"SOFTWARE\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice\"))  //Locates the registry value
            if (myKey != null)
            {
                string val = myKey.GetValue("Progid");
                if (myKey == null)
                {
                    Console.WriteLine("Not found");
                }
                else
                {
                    Console.WriteLine("found key");
                }


                Console.WriteLine("The default browser is already set to Internet Explorer.");
                return;
            }
            else
            {
                try
                {

                    myKey.SetValue("Progid", "IE.HTTP", RegistryValueKind.String); //Sets the 'Progid' value to IE as default browser (IE.HTTP) using String date type
                    Console.WriteLine("The registry key has been changed.", "Title Goes Here"); //Error Checking
                    Console.WriteLine("Press Return to Exit"); //Error Checking
                    input = Console.ReadLine(); //Error Checking
                    return;

                }
                catch
                {
                    Console.WriteLine("There was an error changing the registry key", "Title goes here"); //Error Checking
                    Console.WriteLine("Press Return to Exit"); //Error Checking
                    input = Console.ReadLine(); //Error Checking
                    return;
                }
