将列表中的学生姓名，姓氏和年龄添加到列表框 [英] Add students name,surname and age from list to ListBox

问题描述

我有3个textboxes，可以在其中输入Name，Surname和Age. 在我按下button1之后，它将使新学生具有这些属性.

I have 3 textboxes where I can enter Name,Surname and Age. After i press button1, it makes a new student with these attributes.

如何将具有所有3个属性的学生添加到ListBox? 看起来像这样:

How can I add student with all 3 attributes to ListBox? Look like this:

/#/-名称-姓氏-年龄
1-约翰-史密斯-21
2- 托尼-霍克-22

/#/ -- Name -- Surname -- Age
1 -- John -- Smith -- 21
2 -- Tony -- Hawk -- 22

此刻我的代码:

public class Students
{
     public string Name;
     public string Surname;
     public int Age;
}
public partial class Form1 : Form
{
     List<Students> group = new List<Students>();
     public Form1()
     {
         InitializeComponent();
     }

     private void label1_Click(object sender, EventArgs e)
     {
         Students student = new Students();
         student.Name = textBox1.Text;
         student.Surname = textBox2.Text;
         student.Age = Convert.ToInt32(textBox3.Text);
         group.Add(student);
     }
}

推荐答案

尝试一下:

listBox1.DataSource = group;
listBox1.DisplayMember = "Name"; //Set the DisplayMember property to avoid call ToString()

或者这个:

foreach (var item in group)
{
    listBox1.Items.Add(item);
}
listBox1.DisplayMember = "Name";

还应将类中的字段更改为如下属性:

Also you shoud change the fields in your class to properties like this:

public class Students
{
    public string Name { get; set; }
    public string Surname { get; set; }
    public int Age { get; set; }
    public override string ToString()
    {
        return string.Format("{0} -- {1} -- {2}", Name, Surname, Age);
    }
}

:我认为您想要此操作(通过按一下按钮，它会添加到ListBox中，并且您不再需要group列表.只是不要忘记覆盖ToString在该类中):

I think you want this (By pressing button it adds to the ListBox and you don't need the group list anymore. Just don't forget to override the ToString in the class):

private void button1_Click(object sender, EventArgs e)
{
    Students student = new Students();
    student.Name = textBox4.Text;
    student.Surname = textBox5.Text;
    student.Age = Convert.ToInt32(textBox6.Text);
    listBox1.Items.Add(student);         
}
