示例

以下示例创建一个 ， MouseButtonEventHandler 它确定是发生单次、双击还是三次单击。 ClickCount 属性用于确定单击次数。

private void OnMouseDownClickCount(object sender, MouseButtonEventArgs e)
{
    // Checks the number of clicks.
    if (e.ClickCount == 1)
    {
        // Single Click occurred.
        lblClickCount.Content = "Single Click";
    }
    if (e.ClickCount == 2)
    {
        // Double Click occurred.
        lblClickCount.Content = "Double Click";
    }
    if (e.ClickCount >= 3)
    {
        // Triple Click occurred.
        lblClickCount.Content = "Triple Click";
    }
}

Private Sub OnMouseDownClickCount(ByVal sender As Object, ByVal e As MouseButtonEventArgs)
    ' Checks the number of clicks.
    If e.ClickCount = 1 Then
        ' Single Click occurred.
        lblClickCount.Content = "Single Click"
    End If
    If e.ClickCount = 2 Then
        ' Double Click occurred.
        lblClickCount.Content = "Double Click"
    End If
    If e.ClickCount >= 3 Then
        ' Triple Click occurred.
        lblClickCount.Content = "Triple Click"
    End If
End Sub

注解

的 ClickCount 一个用途是确定是否发生了双击鼠标。 某些类公开双击的事件，例如 MouseDoubleClick 类上的 Control 事件。 当类上未公开双击事件时，可以通过对事件数据使用 ClickCount 属性来检测双击。
