Remarks

The IDictionaryEnumerator.Entry method returns an instance of this type.

The foreach statement of the C# language (for each in Visual C++, For Each in Visual Basic) requires the type of each element in the collection. Since each element of the IDictionary is a key/value pair, the element type is not the type of the key or the type of the value. Instead, the element type is DictionaryEntry. For example:

foreach (DictionaryEntry de in myHashtable) {...}

for each (DictionaryEntry^ de in myHashtable) {...}

For Each de As DictionaryEntry In myHashtable
   ...
Next de

The foreach statement is a wrapper around the enumerator, which only allows reading from, not writing to, the collection.
