我的代码

private void yourListView_SelectedIndexChanged(object sender, EventArgs e)
{
    if (yourListView.SelectedIndex == -1)
        return;
    //get selected row
    ListViewItem item = yourListView.Items[yourListView.SelectedIndex];
    //fill the text boxes
    textBoxID.Text = item.Text;
    textBoxName.Text = item.SubItems[0].Text;
    textBoxPhone.Text = item.SubItems[1].Text;
    textBoxLevel.Text = item.SubItems[2].Text;
}

Answer 1

ListView没有属性SelectedIndex。您应该使用SelectedItems或SelectedIndices。

所以你可以使用它：

private void yourListView_SelectedIndexChanged(object sender, EventArgs e)
{
    if (yourListView.SelectedItems.Count == 0)
        return;    

    ListViewItem item = yourListView.SelectedItems[0];
    //fill the text boxes
    textBoxID.Text = item.Text;
    textBoxName.Text = item.SubItems[0].Text;
    textBoxPhone.Text = item.SubItems[1].Text;
    textBoxLevel.Text = item.SubItems[2].Text;
}

我在此建议将属性MultiSelect设置为false。

C＃和WPF使用它：

private void lv_yourListView_SelectedIndexChanged(object sender, EventArgs 
e)
{
    if (yourListView.SelectedItems.Count == 0)
        return;    

     var item = lvb_listInvoices.SelectedItems[0];
     var myColumnData = item.someField; //use whatever you want
}
