在C#的列中添加到列表视图 [英] Add to listview in columns in C#

问题描述

我有一个class.cs

I have a class.cs

namespace Monit_air_fly
{
    class SearchFlyClass
    {
        public Connectdb conObject = new Connectdb();

        public ArrayList GetFly(int tip, string country, string theDate)
        {
            using (var connection = new SqlConnection(conObject.SetConnection()))
            {
                connection.Open();
                String query = "SELECT ...  = @tip";
                
                using (var command = new SqlCommand(query, connection))
                {
                    command.Parameters.AddWithValue("@tip", tip);
                    var list = new ArrayList();
                    var reader = command.ExecuteReader();
                    if (reader.HasRows)
                    {
                        //MessageBox.Show("Row exist");
                        int cod_zbor = reader.GetOrdinal("cod_zbor");
                        int nume_aeroport = reader.GetOrdinal("nume_aeroport");
                        int nume_companie = reader.GetOrdinal("nume_companie");
                        while (reader.Read())
                        {
                            decimal nr_zbor = reader.GetDecimal(cod_zbor);
                            string aeroport = reader.GetString(nume_aeroport);
                            string companie = reader.GetString(nume_companie);
                            list.Add(nr_zbor);
                            list.Add(companie);
                            list.Add(aeroport);
                        }
                    }
                    reader.Close();
                    connection.Close();
                    return list;
                }
            }
        }
    }
}

我希望按列[zbor，机场，公司]将List1中的列表放到Form1.cs中，但我现在不知道如何

and I wish to put in Form1.cs the list in listview by columns[zbor,airport,company], but I don''t now how

private SearchFlyClass searchFly = new SearchFlyClass();
private ArrayList fly = new ArrayList();
...
private void ShowResultFlySearch(int direction, string country)
        {
                fly = searchFly.GetFly(direction, country);
                for (int count = 0; count < fly.Count; count++)
                {
                    string zbor = fly[0].ToString();
                    string companie = fly[1].ToString();
                    string aeroport = fly[2].ToString();
                    ListViewItem searchlist = new ListViewItem();
                    searchlist.Items.Add(new ListViewItem(elem));

                }
        }

推荐答案

看看 ^ ]

虽然ListView是一个不错的控件，但DataGridView是更适合您的选择.

如果确实要使用ListView，则需要将View属性设置为View.Details，使用Columns集合添加列，然后使用ListViewItem.SubItems集合添加数据.
在此处 [

Have a look at DataGridView Filter Popup[^]

While ListView is a nice control, the DataGridView is a more appropriate choice for you purpose.

If you really want to use the ListView you need to set the View property to View.Details, add columns using the Columns collection, and then use the ListViewItem.SubItems collection to add the data.

An example is available here[^]
