Question

In the case where Dictionary<object, object> myDictionary happens to contain a single item, what is the best way to retrieve the value object (if I don’t care about the key) ?

if (myDictionary.Count == 1)
{
    // Doesn't work
    object obj = myDictionary.Values[0];
}

Thanks

Depending on whether you want it to fail if there’s multiple object or not you can use either

myDictionary.Values.Single(); // Will fail if there's more than one

or

myDictionary.Values.First(); // Will just return the first regardless of the count
