WinForm,ListView,imagelist

//****************************
try
{
int intRow;
SqlDataAdapter objAdapter=new SqlDataAdapter();
DataSet objds=new DataSet();
SqlConnection objCon=new SqlConnection(this.strCon);
objAdapter.SelectCommand=new SqlCommand("select * from db_register order by ID desc",objCon);
objAdapter.Fill(objds,"db_register");
DataTable objTable=null;
objTable=objds.Tables[0];
DataRow objRow=null;
this.lvi.Items.Clear();
for(intRow=0;intRow<objTable.Rows.Count;intRow++)
{
objRow=objTable.Rows[intRow];
ListViewItem lvi=new ListViewItem();
lvi.Text=objRow["UserID"].ToString();
lvi.SubItems.Add(objRow["Name"].ToString());
lvi.SubItems.Add(objRow[2].ToString());
lvi.SubItems.Add(objRow[3].ToString());
lvi.SubItems.Add(objRow[4].ToString());
this.lvi.Items.Add(lvi);
}
this.lvi.EndUpdate();
}
catch(Exception ex)

下面是msdn的例子很好懂，但是请注意是没有办法给subitem设置图标的，这是因为subItem只是设置为显示，而不是控制的
该示例假定已经将该代码添加到某 Form 中，然后从构造函数或此窗体上的另一个方法调用在该示例中创建的方法。该示例还假定名为 MySmallImage1、MySmallImage2、MyLargeImage1 和 MyLargeImage2 的图像位于驱动器 C 的根目录下。
[Visual Basic]
Private Sub CreateMyListView()
' Create a new ListView control.
Dim listView1 As 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.
