Remarks
Use this method to create an System.Collections.IEnumerator-implemented object that can be iterated through to get each item in the HtmlTableRowCollection collection.
Use the IEnumerator.Current property to get the current element in the collection.
Use the IEnumerator.MoveNext method to move to the next item in the collection.
Use the IEnumerator.Reset method to move the enumerator to the initial position.
Note
You must call the IEnumerator.MoveNext method after creating an System.Collections.IEnumerator-implemented object, or after using the IEnumerator.Reset method to move the enumerator to the first item in the collection. Otherwise, the item represented by the IEnumerator.Current property is undefined.
