The foreach statement of the C# language (for each in C++, For Each in Visual Basic) returns an object of the type of the elements in the collection.

Instead, the element type is KeyValuePair<TKey,TValue>. For example:
The foreach statement is a wrapper around the enumerator, which allows only reading from, not writing to, the collection.
