Answer 1

foreach(ListViewItem item in listview.Items)
{
if(listview.Items.Checked == true)
{
string message = “”；
}
}

private void CreateMyListView()
{
// Create a new ListView control.
ListView listView1 = new ListView();
listView1.Bounds = new Rectangle(new Point(10,10), new Size(300,200));

// Set the view to show details.
listView1.View = View.Details;
// Allow the user to edit item text.
listView1.LabelEdit = true;
// Allow the user to rearrange columns.
listView1.AllowColumnReorder = true;
// Display check boxes.
listView1.CheckBoxes = true;
// Select the item and subitems when selection is made.
listView1.FullRowSelect = true;
// Display grid lines.
listView1.GridLines = true;
// Sort the items in the list in ascending order.
listView1.Sorting = SortOrder.Ascending;

// Create three items and three sets of subitems for each item.
ListViewItem item1 = new ListViewItem("item1",0);
// Place a check mark next to the item.
item1.Checked = true;
item1.SubItems.Add("1");
item1.SubItems.Add("2");
item1.SubItems.Add("3");
ListViewItem item2 = new ListViewItem("item2",1);
item2.SubItems.Add("4");
item2.SubItems.Add("5");
item2.SubItems.Add("6");
ListViewItem item3 = new ListViewItem("item3",0);
// Place a check mark next to the item.
item3.Checked = true;
item3.SubItems.Add("7");
item3.SubItems.Add("8");
item3.SubItems.Add("9");

// Create columns for the items and subitems.
listView1.Columns.Add("Item Column", -2, HorizontalAlignment.Left);
listView1.Columns.Add("Column 2", -2, HorizontalAlignment.Left);
listView1.Columns.Add("Column 3", -2, HorizontalAlignment.Left);
listView1.Columns.Add("Column 4", -2, HorizontalAlignment.Center);

//Add the items to the ListView.
listView1.Items.AddRange(new ListViewItem[]{item1,item2,item3});

// Create two ImageList objects.
ImageList imageListSmall = new ImageList();
ImageList imageListLarge = new ImageList();

// Initialize the ImageList objects with bitmaps.
imageListSmall.Images.Add(Bitmap.FromFile("C:\\MySmallImage1.bmp"));
imageListSmall.Images.Add(Bitmap.FromFile("C:\\MySmallImage2.bmp"));
imageListLarge.Images.Add(Bitmap.FromFile("C:\\MyLargeImage1.bmp"));
imageListLarge.Images.Add(Bitmap.FromFile("C:\\MyLargeImage2.bmp"));

//Assign the ImageList objects to the ListView.
listView1.LargeImageList = imageListLarge;
listView1.SmallImageList = imageListSmall;

// Add the ListView to the control collection.
this.Controls.Add(listView1);
}

Answer 2

选中项的文本值：this.listView1.SelectedItems[0].Text;
选中项的子项的文本值
this.listView1.SelectedItems[0].SubItems[0].Text;（SubItems[0]表示选中项的第一个子项，第二个子项就是SubItem[1],第三个就是SubItems[2]....以此类推）

Answer 3

你要Vb.net版的还是C#版的？下面是VB.NET版的：
Dim i As Integer=listview.items.indexof(listview.focuseditem)'首先获得选中项的索引
Msgbox(listview.items(i).subitems(0).text)'弹出消息框显示所选择项的第0列的文本

Answer 4

listBox2.SelectedItem这个就可以了

Answer 5

引用longge7610的回答：
选中项的文本值：this.listView1.SelectedItems[0].Text;
选中项的子项的文本值
this.listView1.SelectedItems[0].SubItems[0].Text;（SubItems[0]表示选中项的第一个子项，第二个子项就是SubItem[1],第三个就是SubItems[2]....以此类推）

private void listView1_ItemSelectionChanged(object sender,EventArgs e)
{ if (listView1.SelectedItems.Count == 0) return;
else
{
string site = listView1.SelectedItems[0].Text;
string type = listView1.SelectedItems[0].SubItems[1].Text;
}
}
需要加一个判断，不然未选中或者鼠标换选项目的时候会报错的
