ListViewreturns collections of selected items and indices through the SelectedItemsand SelectedIndicesproperties. Note that these collections are empty, if no item is currently selected (lst.SelectedItems.Count = 0). The first item that is selected is lst.SelectedItems(0). The index of this item in the Itemscollection is lst.SelectedIndices(0). So basically
ListView通过SelectedItems和SelectedIndices属性返回选定项目和索引的集合。请注意，如果当前未选择任何项目，则这些集合为空 ( lst.SelectedItems.Count = 0)。选择的第一个项目是lst.SelectedItems(0)。该项目在Items集合中的索引是lst.SelectedIndices(0)。所以基本上
lst.SelectedItems(0)
is the same as
是相同的
lst.Items(lst.SelectedIndices(0))
You can also use check boxes. Set CheckBoxesto Truefor this. Through the CheckedItemsand CheckedIndicesproperties you can see which items are checked.
您还可以使用复选框。设置CheckBoxes到True这一点。通过CheckedItems和CheckedIndices属性，您可以查看检查了哪些项目。

If you want to select the same item in a listboxusing a listview, you can use:
如果要listbox使用 a在 a 中选择相同的项目listview，可以使用：
Private Sub ListView1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ListView1.SelectedIndexChanged
For aa As Integer = 0 To ListView1.SelectedItems.Count - 1
ListBox1.SelectedIndex = ListView1.SelectedIndices(aa)
Next
End Sub

ListView.FocusedItem.Index
or you can use foreach loop like this
或者你可以像这样使用 foreach 循环
int index= -1;
foreach (ListViewItem itm in listView1.SelectedItems)
{
if (itm.Selected)
{
index= itm.Index;
}
}

Please Try This for Getting column Index
请尝试此获取列索引
Private Sub lvDetail_MouseMove(sender As Object, e As MouseEventArgs) Handles lvDetail.MouseClick
Dim info As ListViewHitTestInfo = lvDetail.HitTest(e.X, e.Y)
Dim rowIndex As Integer = lvDetail.FocusedItem.Index
lvDetail.Items(rowIndex).Selected = True
Dim xTxt = info.SubItem.Text
For i = 0 To lvDetail.Columns.Count - 1
If lvDetail.SelectedItems(0).SubItems(i).Text = xTxt Then
MsgBox(i)
End If
Next
End Sub
