                End If
            Next
        End If

推荐答案

执行循环后，再次绑定lstTot.希望能解决您的问题.您没有提到如何填充lstTot

After execution of the loop, bind lstTot once again. Hope that will resolve your problem. You didn''t mention how lstTot got populated

在Remove方法中，仅传递"li"代替"li.Text"

In Remove method pass only ''li'' in place of ''li.Text''

这不是从列表中删除项目的正确方法.您可能会遇到错误.

像这样尝试:

This is not a right way to remove items from list. You may get errors.

Try like this:

For Each obj As Object In lstTot.SelectedItems
    lstEx.Items.Add(obj)
Next
While lstTot.SelectedIndices.Count > 0
      lstTot.Items.RemoveAt(lstTot.SelectedIndices.Item(0))
End While
