Why use a dictionary if you want to access the data using a sequential index? In what circumstance could position `1` return `Water`? — CodingIntrigue, Feb 06 '14 at 12:21
I am unsure of what you are trying to accomplish... Why are you using an Ordered Dictionary and what do you want to do ? If we know more, we could help you better — KapteinMarshall, Feb 06 '14 at 12:23

Try this :

For value:

 var result= (Drinks.Cast<DictionaryEntry>().ElementAt(2)).Value;

For Key

var result= (Drinks.Cast<DictionaryEntry>().ElementAt(2)).Key;

Close. OP would like the `Key`, rather than the `Value`. Other than that, this works as requested - http://ideone.com/rmAU1h – CodingIntrigue Feb 06 '14 at 12:42

Try this,

var result = Drinks.Keys.OfType<string>().ElementAt(0);

This will return first key of OrderedDictionary. Here you are sure that your key type is string. but if you are not sure data type of key then use object

like,

var result = Drinks.Keys.OfType<object>().ElementAt(0);
