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

Syntax

'Declaration
Private ReadOnly Property Current As Object
    Implements IEnumerator.Current

Object IEnumerator.Current { get; }

Property Value

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

Implements

IEnumerator.Current

Exceptions

Exception Condition
InvalidOperationException

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

Remarks

Current 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 Reset is called. MoveNext 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.

Current 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 if the enumerator is already invalidated.
