看了 看不懂

看看BdListView中的listView1.Items.Clear();会不会触发listView1_SelectedIndexChanged，这样就有可能引发越界访问错误，你组好在listView1_SelectedIndexChanged中加一个容错的判断吧

[牛哥_]

private void listView1_SelectedIndexChanged(object sender, EventArgs e)
{
if (listView1.SelectedItems.Count > 0)
{
ListViewItem li = new ListViewItem();
txttitle.Text=li.SubItems[0].Text;
comType.Text = li.SubItems[1].Text;
comtq.Text=li.SubItems[2].Text;
dateTimePicker1.Text=li.SubItems[3].Text;
myRichTextBox1.Text=li.SubItems[4].Text;
string re = li.SubItems[0].Text + li.SubItems[1].Text + li.SubItems[2].Text + li.SubItems[3].Text + li.SubItems[4].Text;
indexs = al.IndexOf(re);
}
}
刚才是ListViewItem li = new ListViewItem();错了 改成ListViewItem li = listView1.SelectedItems[0];后 变成InvalidArgument=“3”的值对于“index”无效。就是 dateTimePicker1.Text=li.SubItems[3].Text;出错了 怎么解决呢
