Примеры

These examples show two ways to enumerate the Strokes collection in order to retrieve each Stroke object contained in the collection. The Strokes collection is returned by the Ink.Strokes property.

This example obtains the IEnumerator for the Strokes collection, and uses it to traverse the collection.

Private Sub EnumerateStrokesWithEnumerator(ByVal mInk As Ink)
    ' access the Strokes property via using statement
    ' to insure that the object mStrokes is disposed when finished
    ' Otherwise, you will have a memory leak
    Using mStrokes As Strokes = mInk.Strokes
        Dim mStrokesEnumerator As IEnumerator = mStrokes.GetEnumerator()
        mStrokesEnumerator.Reset()
        While (mStrokesEnumerator.MoveNext())
            Dim S As Stroke = DirectCast(mStrokesEnumerator.Current, Stroke)
            Me.listBoxStrokeId.Items.Add(S.Id)
        End While
    End Using
End Sub

private void EnumerateStrokesWithEnumerator(Ink mInk)
{
    // access the Strokes property via using statement
    // to insure that the object mStrokes is disposed when finished
    // Otherwise, you will have a memory leak
    using (Strokes mStrokes = mInk.Strokes)
    {
        IEnumerator mStrokesEnumerator = mStrokes.GetEnumerator();
        mStrokesEnumerator.Reset();
        while (mStrokesEnumerator.MoveNext())
        {
            Stroke S = (Stroke)mStrokesEnumerator.Current;
            this.listBoxStrokeId.Items.Add(S.Id);
        }
    }
}

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

Private Sub EnumerateStrokesWithForEach(ByVal mInk As Ink)
    ' access the Strokes property via using statement
    ' to insure that the object mStrokes is disposed when finished
    ' Otherwise, you will have a memory leak
    Using mStrokes As Strokes = mInk.Strokes
        For Each S As Stroke In mStrokes
            Me.listBoxStrokeId.Items.Add(S.Id)
        Next
    End Using
End Sub

private void EnumerateStrokesWithForEach(Ink mInk)
{    
    // access the Strokes property via using statement
    // to insure that the object mStrokes is disposed when finished
    // Otherwise, you will have a memory leak
    using (Strokes mStrokes = mInk.Strokes)
    {
        foreach (Stroke S in mStrokes)
        {
            this.listBoxStrokeId.Items.Add(S.Id);
        }
    }
}
