C# 如何将数据表中的项添加到listview？

我目前正在开发一个C Windows窗体应用程序

现在，我尝试使用SQL命令从数据库中检索信息，以填充应用程序中需要的信息

示例查询将是select*from Location

在Location表中会有locationId、LocationName、districId等变量。 我使用了以下代码

private void button1_Click(object sender, EventArgs e)
{
    SqlConnection con = new SqlConnection("connectionstring");
    SqlDataAdapter ada = new SqlDataAdapter("select * from MasterLocation", con);
    DataTable dt = new DataTable();
    ada.Fill(dt);

    for (int i = 0; i < dt.Rows.Count; i++)
    {
        DataRow dr = dt.Rows[i];
        ListViewItem listitem =new ListViewItem(dr["pk_Location_ID"].ToString());
        listitem.SubItems.Add(dr["var_Location_Name"].ToString());
        listitem.SubItems.Add(dr["fk_int_District_ID"].ToString());
        listitem.SubItems.Add(dr["fk_int_Company_ID"].ToString());
       listView1.Items.Add(listitem);
    } 

输出为：

但应该是这样的：

您必须更改一些代码

private void button1_Click(object sender, EventArgs e)
{
    listView1.View = View.Details;
    SqlConnection con = new SqlConnection("connectionstring");
    SqlDataAdapter ada = new SqlDataAdapter("select * from MasterLocation", con);
    DataTable dt = new DataTable();
    ada.Fill(dt);

    for (int i = 0; i < dt.Rows.Count; i++)
    {
        DataRow dr = dt.Rows[i];
        ListViewItem listitem = new ListViewItem(dr["pk_Location_ID"].ToString());
        listitem.SubItems.Add(dr["var_Location_Name"].ToString());
        listitem.SubItems.Add(dr["fk_int_District_ID"].ToString());
        listitem.SubItems.Add(dr["fk_int_Company_ID"].ToString());
       listView1.Items.Add(listitem);
    }

        listitem.SubItems.Add(dr["fk_int_Company_ID"].ToString());
       listView1.Items.Add(listitem);
    } 

添加了以下代码

listView1.View = View.Details;

它成功了

 private void FormView_Load(object sender, EventArgs e)
  {
    sample = new DataTable(); //Sample Data
            sample.Columns.Add("id", typeof(string));
            sample.Columns.Add("name", typeof(string));
            sample.Rows.Add("1", "apple");
            sample.Rows.Add("2", "acer");
            sample.Rows.Add("3", "alpha");
            sample.Rows.Add("4", "beat");
            sample.Rows.Add("5", "ball");
            sample.Rows.Add("6", "cat");
            sample.Rows.Add("7", "catch");
            sample.Rows.Add("10", "zebra");

            listViewEx1.View = View.Details;
            listViewEx1.Columns.Add("id");
            listViewEx1.Columns.Add("name");
  }



         listViewEx1.Items.Clear();

            listViewEx1.FullRowSelect = true;

            foreach (DataRow row in sample.Rows)
            {
                    ListViewItem item = new ListViewItem(row["id"].ToString());
                    item.SubItems.Add(row["name"].ToString());
                    listViewEx1.Items.Add(item); //Add this row to the ListView
             }

添加了以下代码

listView1.View = View.Details;

那么你想要什么样的输出？为什么不使用？这正是图像上显示的您希望它是什么样子的，您还可以在其上绑定一个数据源。那么您想要什么类型的输出呢？为什么不使用？这正是图像上显示的您希望它的样子，您还可以在上面绑定一个数据源
