命名空間： Microsoft.Ink
組件： Microsoft.Ink (在 Microsoft.Ink.dll 中)

語法

'宣告
Public Function Contains ( _
    ep As ExtendedProperty _
) As Boolean
'用途
Dim instance As ExtendedProperties
Dim ep As ExtendedProperty
Dim returnValue As Boolean

returnValue = instance.Contains(ep)

public bool Contains(
    ExtendedProperty ep
)

public:
bool Contains(
    ExtendedProperty^ ep
)

public boolean Contains(
    ExtendedProperty ep
)

public function Contains(
    ep : ExtendedProperty
) : boolean

參數

ep
型別：Microsoft.Ink.ExtendedProperty
要檢查的 ExtendedProperty 物件。

傳回值

型別：System.Boolean
如果 ExtendedProperties 集合包含特定的 ExtendedProperty 物件，則為 true，否則為 false。

範例

這個範例會檢查提供的 Strokes 集合中的每個 Stroke 物件。如果 Stroke 物件包含提供之 ExtendedProperties 集合中的所有擴充屬性，便會將 Stroke 修改為以不同的色彩顯示。

Private Sub HighlightLikeStrokes(ByVal ep As ExtendedProperties, ByVal theStrokes As Strokes)
    If ep.Count > 0 Then
        For Each theStroke As Stroke In theStrokes
            Dim containsCount As Integer = 0
            For k As Integer = 0 To ep.Count
                If theStroke.ExtendedProperties.Contains(ep(k)) Then
                    containsCount += 1
                End If
            Next
            ' If all the extended properties are there, color the stroke blue
            If containsCount = ep.Count Then
                theStroke.DrawingAttributes.Color = Color.PowderBlue
            End If
        Next
        mInkOverlay.AttachedControl.Invalidate()
    End If
End Sub

private void HighlightLikeStrokes(ExtendedProperties ep, Strokes theStrokes)
{
    if (ep.Count > 0)
    {
        foreach (Stroke theStroke in theStrokes)
        {
            int containsCount = 0;
            for (int k = 0; k < ep.Count; k++)
            {
                if (theStroke.ExtendedProperties.Contains(ep[k]))
                {
                    containsCount++;
                }
            }
            // If all the extended properties are there, color the stroke blue
            if (containsCount == ep.Count)
            {
                theStroke.DrawingAttributes.Color = Color.PowderBlue;
            }
        }
        mInkOverlay.AttachedControl.Invalidate();
