Gets the current element in the collection.
Assembly: mscorlib (in mscorlib.dll)
The enumerator is positioned before the first element of the collection or after the last element.
After an enumerator is created or 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 the property; otherwise, is undefined.
also throws an exception if the last call to MoveNext returned false, which indicates the end of the collection.
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 , returns the element that it is set to, even if the enumerator is already invalidated.
