If you want to do it in a listbox you will need to do it manually. Add a tooltip to the form and update the tooltip based on the mouses postion. An easier way to do this might be to use a DataGridView control like this:
如果您想在列表框中执行此操作，则需要手动执行此操作。向表单添加工具提示并根据鼠标位置更新工具提示。一种更简单的方法可能是使用像这样的 DataGridView 控件：
DataGridView1.RowHeadersVisible = False
DataGridView1.ColumnHeadersVisible = False
DataGridView1.Columns(0).AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCellsExceptHeader
Dim mydata As String() = {"Item 1", "Item 2", "Item 3", "Item 4", "Item 5", "Item 6"}
For Each dataitem As String In mydata
DataGridView1.Rows.Add(dataitem)
Next
For Each row As DataGridViewRow In DataGridView1.Rows
row.Cells(0).ToolTipText = "ToolTip for " & row.Cells(0).Value
Next row

I thought I'd mention that there is a ShowItemToolTipsboolean attribute on ListView, if you want to use that instead of a ListBox. Set that attribute to trueand then assign the ToolTipTextvalues on the ListViewitems.
我想我会提到 上有一个ShowItemToolTips布尔属性ListView，如果你想使用它而不是ListBox. 将该属性设置为true，然后ToolTipText在ListView项目上分配值。

I able to resolve thorough below ways:
我能够通过以下方式彻底解决：
'tooltip
Dim toolTip As ToolTip = New ToolTip()
Private Sub lstReports_MouseMove(sender As Object, e As MouseEventArgs) Handles lstReports.MouseMove
Dim index As Integer = lstReports.IndexFromPoint(e.Location)
If (index <> -1 AndAlso index < lstReports.Items.Count) Then
If (toolTip.GetToolTip(lstReports) <> lstReports.Items(index).ToString()) Then
toolTip.SetToolTip(lstReports, lstReports.Items(index).ToString())
End If
End If
End Sub

Sadly, there is no implemented way to show ToolTips on each individual ListBox Item.
遗憾的是，没有实现在每个单独的 ListBox 项上显示工具提示的方法。
You can create your own ListBox control that allows you to do that, like this one: http://www.codeproject.com/Articles/457444/Listbox-Control-with-Tooltip-for-Each-Item
您可以创建自己的 ListBox 控件，允许您执行此操作，例如：http: //www.codeproject.com/Articles/457444/Listbox-Control-with-Tooltip-for-Each-Item
