IEnumerator.MoveNext()

Заметки

The CustomStrokes.CustomStrokesEnumerator supports iterating over a CustomStrokes collection and implements the System.Collections.IEnumerator interface.

This method inherits from System.Collections.IEnumerator.MoveNext.

Примеры

These examples show two ways to enumerate the CustomStrokes collection in order to retrieve each Strokes object contained in the collection.

This example obtains the IEnumerator for the CustomStrokes collection, and uses it to traverse the collection. Each Strokes object is then scaled by a factor of 2.

Private Sub EnumerateCustomStrokesWithEnumerator(ByVal mInk As Ink)
    Dim mCustomStrokesEnumerator As IEnumerator = mInk.CustomStrokes.GetEnumerator()
    mCustomStrokesEnumerator.Reset()
    While (mCustomStrokesEnumerator.MoveNext())
        Dim S As Strokes = DirectCast(mCustomStrokesEnumerator.Current, Strokes)
        S.Scale(2, 2)
    End While
End Sub

private void EnumerateCustomStrokesWithEnumerator(Ink mInk)
{
    IEnumerator mCustomStrokesEnumerator = mInk.CustomStrokes.GetEnumerator();
    mCustomStrokesEnumerator.Reset();
    while (mCustomStrokesEnumerator.MoveNext())
    {
        Strokes S = (Strokes)mCustomStrokesEnumerator.Current;
        S.Scale(2, 2);
    }
}

This example uses the foreach statement, which calls the GetEnumerator method in internal code that the compiler generates to support the statement.

Private Sub EnumerateCustomStrokesWithForEach(ByVal mInk As Ink)
    For Each S As Strokes In mInk.CustomStrokes
        S.Scale(2, 2)
    Next
End Sub

private void EnumerateCustomStrokesWithForEach(Ink mInk)
{
    foreach (Strokes S in mInk.CustomStrokes)
    {
        S.Scale(2, 2);
    }

}
