在列表框中的消息框中显示多个信息

本文关键字：信息 显示 列表 消息 | 更新日期: 2023-09-27 18:31:21

我正在开发一个程序，让我输入有关船只的信息并将该信息添加到列表框中。 列表框中唯一显示的是船的名称。 我需要知道如何在消息框中显示其他文本框中的所有信息，例如长度、帆尺寸和引擎。任何帮助，不胜感激。

public partial class Form1 : Form
{
    ArrayList Home;
    public Form1()
    {
        InitializeComponent();
        Home = new ArrayList();
    }
    private void btnAddApartment_Click(object sender, EventArgs e)
    {
        //instantiate appartment and add it to arraylist
        try
        {
            Apartment anApartment = new Apartment(txtID.Text, txtAddress.Text, int.Parse(txtYearBuilt.Text), int.Parse(txtBedrooms.Text),
                double.Parse(txtSquareFootage.Text), double.Parse(txtPrice.Text), txtFurnished.Text);
            Home.Add(anApartment);
            ClearText(this);
        }
        catch (Exception)
        {
            MessageBox.Show("Make sure you entered everything correctly!", "Error", MessageBoxButtons.OK);
        }            
    }
    private void btnAddHouse_Click(object sender, EventArgs e)
    {
        try 
        {
            House aHouse=new House(txtID.Text, txtAddress.Text, int.Parse(txtYearBuilt.Text), int.Parse(txtBedrooms.Text),
                double.Parse(txtSquareFootage.Text), double.Parse(txtPrice.Text),int.Parse(txtGarageCapacity.Text));
            Home.Add(aHouse);
            AddHouseToListBox();
            ClearText(this);
        }
        catch (Exception)
        {
            MessageBox.Show("Make sure you entered everything correctly!", "Error", MessageBoxButtons.OK);
        }
    }
    private void ClearText(Control controls)
    {
        foreach (Control control in controls.Controls)
        {
            if (control is TextBox)
            {
                ((TextBox)control).Clear();
            }
        }
    }
    private void AddHouseToListBox()
    {
        lstHouse.Items.Clear();
        foreach (House person in Home)
        {
            lstHouse.Items.Add(person.GetAddress());
        }
    }
    private void AddApartmentToListBox()
    {
        lstApartment.Items.Clear();
        foreach (Apartment persons in Home)
        {
            lstApartment.Items.Add(persons.GetAddress());
        }
    }

在列表框中的消息框中显示多个信息

如果要在 ListBox 中显示多列数据，则应考虑切换到 ListView。

然后，您将使用类似于以下内容的代码添加其他列值：

将列表视图控件添加到窗体。

假设你有 4 个文本框，分别名为 txtBoatName、txtLength、txtSailSize、txtEngines

// You can either set the columns and view in code like below, or use
// the Form designer in Visual Studio to set them.  If you set them in code,
// place the following in Form.Load
listView1.View = View.Details;
listView1.Columns.Add("Boat Name", -2, HorizontalAlignment.Left);
listView1.Columns.Add("Length", -2, HorizontalAlignment.Left);
listView1.Columns.Add("Sail Size", -2, HorizontalAlignment.Left);
listView1.Columns.Add("Engines", -2, HorizontalAlignment.Center);
// When you want to add a boat to the ListView, use code like the following:
ListViewItem item1 = new ListViewItem(txtBoatName.Text,0);
item1.SubItems.Add(txtLength.Text);
item1.SubItems.Add(txtSailSize.Text);
item1.SubItems.Add(txtEngines.Text);
listView1.Items.Add(item1);
