refresh a listbox vb.net
提问by user2120280
I have a list Box that contains the names of several files. I can select a file name and click delete. The file will then be removed from my rackspace account. How do I automatically refresh the listBox with out restarting my application?
我有一个包含多个文件名称的列表框。我可以选择一个文件名，然后单击删除。然后该文件将从我的 rackspace 帐户中删除。如何在不重新启动应用程序的情况下自动刷新列表框？
I have tried the following
我已经尝试了以下
listBox.refresh()
listBox.Update()
and neither give me the result I'm looking for.
并且都没有给我我正在寻找的结果。

If you want to remove items from a ListBoxyou have multiple options. You can reload the DataSource that you are using or you can simple remove them from the Itemsby using ListBox.Items.Remove(item)or ListBox.Items.RemoveAt(index).
如果您想从 a 中删除项目，ListBox您有多种选择。您可以重新载入数据源您正在使用，也可以从简单的删除它们Items使用 ListBox.Items.Remove(item)或ListBox.Items.RemoveAt(index)。
private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
{
int index = listBox1.SelectedIndex;
listBox1.Items.RemoveAt(index);
// or
object item = listBox1.SelectedItem;
listBox1.Items.Remove(item);
}
