Answer 1

NOTE

The generic Dictionary class, introduced in .NET 2.0, uses KeyValuePair.

ITs better you make use of

Dictionary.ICollection>

and use ContainsKey Method to check the the key is there or not ..

Example :

ICollection> openWith =
            new Dictionary();
openWith.Add(new KeyValuePair("txt", "notepad.exe"));
openWith.Add(new KeyValuePair("bmp", "paint.exe"));
openWith.Add(new KeyValuePair("dib", "paint.exe"));
openWith.Add(new KeyValuePair("rtf", "wordpad.exe"));

if (!openWith.ContainsKey("txt"))
{
       Console.WriteLine("Contains Given key");
}

---

EDIT

To get value

string value = "";
if (openWith.TryGetValue("tif", out value))
{
    Console.WriteLine("For key = \"tif\", value = {0}.", value);
    //in you case 
   //var list= dict.Values.ToList(); 
}

in your caseu it will be

var list= dict.Values.ToList();
