Moves the enumerator index to the next object in the collection.

Namespace: Microsoft.Ink
Assembly: Microsoft.Ink (in Microsoft.Ink.dll)

Syntax

'Declaration
Public Function MoveNext As Boolean
'Usage
Dim instance As CustomStrokes.CustomStrokesEnumerator 
Dim returnValue As Boolean 

returnValue = instance.MoveNext()

public bool MoveNext()

public:
virtual bool MoveNext() sealed

public final function MoveNext() : boolean

Return Value

Type: System.Boolean
true if the index position references an object; false if the index position references the end of the collection.

Implements

IEnumerator.MoveNext()

Remarks

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

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

Examples

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);
    }

}
