Question

I want to do something with each object in a C# Dictionary. keyVal.Value seems a little awkward:

foreach (KeyValuePair<int, Customer> keyVal in customers) {
    DoSomething(keyVal.Value);
}

Is there a nicer way to do this that’s also fast?

Answer 1

The Dictionary class has a Values property that you can directly iterate over:

foreach(var cust in customer.Values)
{
  DoSomething(cust);
}

An alternative, if you can use LINQ as Arie van Someren shows in his answer:

customers.Values.Select(cust => DoSomething(cust));

Or:

customers.Select(cust => DoSomething(cust.Value));
