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

object IDictionaryEnumerator.Key { get; }

Property Value

Type: System.Object

The key of the element in the dictionary at the current position of the enumerator.

Exception Condition
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 is called, MoveNext must be called to advance the enumerator to the first element of the collection before reading the value of Key; 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 returns the same object until MoveNext is called. MoveNext sets Key to the next element.
