Linq.Lookup is cool and all, but if your target is to simply loop over the "keys" while allowing them to be duplicated you can use this structure:

List> FieldPatterns = new List>() {
   new KeyValuePair("Address","CommonString"),
   new KeyValuePair("Username","UsernamePattern"),
   new KeyValuePair("Username","CommonString"),
};

Then you can write:

foreach (KeyValuePair item in FieldPatterns)
{
   //use item.Key and item.Value
}
