DbEnumerator.Current Property

Gets the current element in the collection.

Namespace:  System.Data.Common
Assembly:  System.Data (in System.Data.dll)

public Object Current { get; }

Property Value

Type: System.Object
The current element in the collection.

Implements

IEnumerator.Current

ExceptionCondition
InvalidOperationException

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

After an enumerator is created or after a Reset, MoveNext must be called to advance the enumerator to the first element of the collection before reading the value of Current; otherwise, Current is undefined. Current also throws an exception if the last call to MoveNext returned false, which indicates the end of the collection. Current does not move the position of the enumerator and consecutive calls to Current return the same object until either MoveNext or Reset is called. An enumerator remains valid as long as the collection remains unchanged. If changes are made to the collection, such as adding, modifying or deleting elements, the enumerator is irrecoverably invalidated and the next call to MoveNext or Reset generates an InvalidOperationException. If the collection is modified between MoveNext and Current, Current returns the element to which it is set, even if the enumerator is already invalidated.
