SortedDictionary<TKey, TValue>.KeyCollection.Enumerator.IEnumerator.Current Property

Gets the element at the current position of the enumerator.

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

Object IEnumerator.Current { get; }

Property Value

Type: System.Object
The element in the collection at the current position of the enumerator.

Implements

IEnumerator.Current

ExceptionCondition
InvalidOperationException

The enumerator is positioned before the first element of the collection or after the last element.

The Current property is undefined under any of the following conditions:

  • The enumerator is positioned before the first element in the collection, immediately after the enumerator is created or immediately 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 Current.

  • The last call to MoveNext returned false, which indicates the end of the collection.

The Current property returns the same object until MoveNext or Reset is called. MoveNext sets Current to the next element. If the collection is modified between MoveNext and Current, Current returns the element that it is set to, even though the enumerator is invalidated.
