ListView 选择多项目返回的之前的那项

当ListView多选时返回第一次选中的项索引

正确

定义一个变量

=-1 表示第一次没选任何一项

private int FirstSelectedIndex =-1;

更新FirstSelectedIndex 的值一定要放在Mouse_Click

放在 listView1_SelectedIndexChanged或listView1_ItemSelectionChanged无效

private void listView1_MouseClick(object sender, MouseEventArgs e)

{

int count = listView1.SelectedItems.Count;

if (count > 0)

{

int Index = listView1.SelectedItems[0].Index;

if (count == 1)

FirstSelectedIndex = Index;

}

高亮选中第一次选择的项

Form1_Click

private void Form1_Click(object sender, EventArgs e)

{

if (listView1.Items.Count > 0)

{

if (FirstSelectedIndex != -1)

{

//RUN

listView1.MultiSelect = false;

listView1.Focus();

Text = listView1.Items[FirstSelectedIndex].Text;

listView1.Items[FirstSelectedIndex].Selected = true;

listView1.MultiSelect = true;

}

if ((FirstSelectedIndex == -1) && (listView1.SelectedItems.Count > 0))

{
