C# C如何加载listview

我正在做一个windows窗体应用程序来打开和加载数据库。代码需要显示记录的单记录视图和listView视图，但是我被listView部分卡住了

下面是下面的代码

using System;
using System.IO;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Data.OleDb;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using ADOX;

namespace Ex3

    public partial class changeButton : Form
    {

        public string filename;
        public string fileDir;
        public string rec;
        public bool checkBC;

我希望能够将代码放在这里，当我从上方单击加载按钮时，它应该加载listview

要加载listview，我将使用以下函数-它使用字符串数组，listviewitem会向listview添加项目

private void LoadListview()
{
    string NAME = "John DOE";
    string AGE = "30";
    string SEX = "MALE";
    string DOB = "08/28/1988";

    string[] rowa = { NAME, AGE, SEX, DOB };
    var listViewItema = new ListViewItem(rowa);

    listView1.Items.Add(listViewItema);
    listView1.Items.Add(listViewItema);
    listView1.Items.Add(listViewItema);
    listView1.Items.Add(listViewItema);

}

你可以在我的网站上找到一个分步详细的答案：

你到底坚持什么？ListView具有可以用ListViewItems填充的.Items属性。您确定不想改为使用DataGrid吗？我希望能够在loadButton\u Click\u 1事件中显示完整的数据库视图，而不是打印命令？ListView是一个经常被滥用的控件。它不是网格控件。除非需要多个视图或分组，否则不应使用ListView。使用更简单、更恰当的方法，即填充一个列表（可能是DataTable或其他内容），并将其绑定到DataGridView。

private void LoadListview()
{
    string NAME = "John DOE";
    string AGE = "30";
    string SEX = "MALE";
    string DOB = "08/28/1988";

    string[] rowa = { NAME, AGE, SEX, DOB };
    var listViewItema = new ListViewItem(rowa);

    listView1.Items.Add(listViewItema);
    listView1.Items.Add(listViewItema);
    listView1.Items.Add(listViewItema);
    listView1.Items.Add(listViewItema);

}
