What is the best way to iterate over a dictionary? [closed]

foreach(KeyValuePair entry in myDictionary)
{
// do something with entry.Value or entry.Key
}

If you are trying to use a generic Dictionary in C# like you would use an associative array in another language:
foreach(var item in myDictionary)
{
foo(item.Key);
bar(item.Value);
}

Or, if you only need to iterate over the collection of keys, use
foreach(var item in myDictionary.Keys)
{
foo(item);
}

And lastly, if you’re only interested in the values:
foreach(var item in myDictionary.Values)
{
foo(item);
}

(Take note that the var keyword is an optional C# 3.0 and above feature, you could also use the exact type of your keys/values here)
