I'm trying to create the C # equivalent of this for each in java but I'm not very clear on how to do it. Any ideas?

for (Map.Entry<Integer, String> entry : hashSoc.entrySet()) {
                dq.write(entry.getValue());
                System.out.println("TSend: " + entry.getValue());

                inventory.deleteRecSocket(entry.getKey());
                inventory.addToSendSocket(entry.getValue());
            }

What I have tried:

I'm trying to convert this for each to your C # equivalent, but the dictionary class does not contain the setEntry.
