What is the best way to iterate over a dictionary?

There iterate of dictionary in C# use

foreach (KeyValuePair item in myDictionary)

{

    MessageBox.Show(item.Key + "   " + item.Value);

}

We can also use loops as sometime we need to keep track of counter values.

for (int count = 0; count < myDictionary.Count; count++)

{

    var element = myDictionary.ElementAt(count);

    var Key = element.Key;

    var Value = element.Value;

    MessageBox.Show(Key + "  " + Value);

}

In some cases you may need a counter that may be provided by for-loop implementation. For that, LINQ provides ElementAt which enables the following:

for (int index = 0; index < dictionary.Count; index++) {
var item = dictionary.ElementAt(index);
var itemKey = item.Key;
var itemValue = item.Value;
}
