IDictionaryEnumerator.Key Property

Gets the key of the current dictionary entry.

Namespace:  System.Collections
Assembly:  mscorlib (in mscorlib.dll)

Object Key { get; }

Property Value

Type: System.Object
The key of the current element of the enumeration.

ExceptionCondition
InvalidOperationException

The IDictionaryEnumerator is positioned before the first entry of the dictionary or after the last entry.

After an enumerator is created or after the Reset method is called, the MoveNext method must be called to advance the enumerator to the first element of the collection before reading the value of the Key property; otherwise, Key is undefined.

Key also throws an exception if the last call to MoveNext returned false, which indicates the end of the collection.

Key does not move the position of the enumerator, and consecutive calls to Key return the same object until either MoveNext or Reset is called.
