属性值
The current element in the collection.
备注
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 throws an InvalidOperationException. If the collection is modified between MoveNext and Current, Current will return the element that it is set to, even if the enumerator is already invalidated.
