Okay, I think I've settled on this:
var result = from pair in data
group pair by pair.Value into g
select g.FormatReverseMapping();
foreach (string s in result)
Console.WriteLine(s);
with an extension method:
internal static string FormatReverseMapping(this IGrouping> grouping)
{
StringBuilder buffer = new StringBuilder();
buffer.Append(grouping.Key);
buffer.Append("=>");
foreach (var x in grouping)
buffer.Append(x.Key);
return buffer.ToString();
}
(psst-- take a look at Systems.Collections.Generic.KeyValuePair.)
