你可以使用VisualTreeHelper来获取ListBox的滚动条。下面是一个示例代码:
```csharp
ScrollBar scrollBar = null;
for (int i = 0; i < VisualTreeHelper.GetChildrenCount(listBox); i++)
{
DependencyObject child = VisualTreeHelper.GetChild(listBox, i);
if (child is ScrollViewer)
{
for (int j = 0; j < VisualTreeHelper.GetChildrenCount(child); j++)
{
DependencyObject subChild = VisualTreeHelper.GetChild(child, j);
if (subChild is ScrollBar)
{
scrollBar = subChild as ScrollBar;
break;
}
}
}
}
if (scrollBar != null)
{
// do something with the scroll bar
}
```
该代码首先遍历ListBox的所有子元素以找到ScrollViewer,然后在ScrollViewer的子元素中查找ScrollBar。如果找到了ScrollBar,它将被赋值给变量scrollBar,然后你可以使用它来执行所需的操作。
