项目
11/04/2008

指示 ExtendedProperties 集合是否包含特定的 ExtendedProperty 对象。

命名空间： Microsoft.Ink
程序集： Microsoft.Ink（在 Microsoft.Ink.dll 中）

语法

声明
Public Function Contains ( _
    ep As ExtendedProperty _
) As Boolean
用法
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

参数

ep
类型：Microsoft.Ink.ExtendedProperty
要检查的 ExtendedProperty 对象。

返回值

类型：System.Boolean
如果 ExtendedProperties 集合包含特定的 ExtendedProperty 对象，则为 true；否则为 false。

示例

此示例检查提供的 Strokes 集合中的每个 Stroke 对象。如果 Stroke 对象包含提供的 ExtendedProperties 集合中的所有扩展属性，则修改 Stroke 以不同的颜色进行显示。

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();
    }
