Looping

foreach (System.Collections.Generic.KeyValuePair<int, string> objKeyValuePair in dicItems) 
{ 
   Debug.Print objKeyValuePair.Key + " - " + objKeyValuePair.Value; 
} 

for (int icount = 0; icount < MyDictionary.Count; icount++) 
{ 
   skey = MyDictionary.ElementAt(icount).Key 
} 

Converting to an array first

string snamesarray; 

snamesarray = dicAuthors.ToArray 
for (int icount = 0; icount < MyDictionary.Count; icount++) 
{ 
   snamesarray.GetValue(icount) 
}
