member this.Current : 'Key
Public ReadOnly Property Current As TKey

Property Value


The element in the Dictionary<TKey,TValue>.KeyCollection at the current position of the enumerator.



Current is undefined under any of the following conditions:

  • The enumerator is positioned before the first element of the collection. That happens after an enumerator is created or after the IEnumerator.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 Current property.

  • The last call to MoveNext returned false, which indicates the end of the collection and that the enumerator is positioned after the last element of the collection.

  • The enumerator is invalidated due to changes made in the collection, such as adding, modifying, or deleting elements.

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