Question

为什么C#中在窗体里加了个ListView循环读数据时候多出来最上面一行的default

后台代码：using System.Text;
using System.Windows.Forms;
using BLL;
using Model;

namespace caixing.User
{
public partial class SuperUser : Form
{
public SuperUser()
{
InitializeComponent();
}

private void SuperUser_Load(object sender, EventArgs e)
{

List<UserInfo> list = (List<UserInfo>)UserManage.GetUserAll();

for (int i = 0; i < list.Count; i++)
{
UserInfo user = new UserInfo();
user = list[i];
ListViewItem lv = new ListViewItem(user.UserName.ToString());

lv.Tag = user.UserId;
lv.SubItems.AddRange(new string[] { user.PassWord });
listView1.HeaderStyle = ColumnHeaderStyle.Clickable;
listView1.Items.Add(lv);

}

}
}
}

Answer 1

你的版本跟举咐历我不一样么?我没有SubItems只有Items耶...
出现正搜的那个简灶Default是组,你不小心加的??试试
lv.Groups.Clear();

Answer 2

试试在for循环前面加一句代码:

lv.Items.Clear();
