如何将数据表中的项添加到列表视图？

Question

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,以填写我在应用程序中需要的信息.

示例查询将是"select*from Location"

在Location表中会有诸如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);
    } 

输出是:

但它应该是这样的:

你必须改变一些代码

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);
    }
