c# - Joining two dictionaries -

hi have 2 dictionaries , need find way join them together.here 2 dictionary types.

idictionary<string, byte[]> dictionary1 idictionary<ifilesharedocument, string> dictionary2 

out of 2 dictionaries have create third dictionary this

idictionary<ifilesharedocument, byte[]> dictionary3 

both dictionaries have exact same number of items , string property of both them linking point.

what able write somethign this:

dictionary1.value join dictionary2.key dictionary1.key == dictionary2.value  statement should result in dictionary3. 

is there way can achieve can not seem find way this?

here's way using linq query syntax, join (this compiles same thing @kingking's solution):

idictionary<ifilesharedocument, byte[]> dictionary3 =     (from item1 in dictionary1      join item2 in dictionary2 on item1.key equals item2.value      select new { item2.key, item1.value })          .todictionary(x => x.key, x => x.value); 

note above preferred example using from , where, because more efficient. i'm including here because if you're me (more familiar sql, convert join automatically), poor way might first 1 comes mind:

idictionary<ifilesharedocument, byte[]> dictionary3 =     (from item1 in dictionary1      item2 in dictionary2      item1.key == item2.value      select new { item2.key, item1.value })          .todictionary(x => x.key, x => x.value);
