标签或文本框上的列表框索引显示

Question

是否有人知道如何使用Listbox SelectedIndexChanged事件的以下命令。请告诉我。我从互联网拿这个例子，我只是想知道如何使用ListBox而不是ListView。

当我没有得到列表框上选定的项目[0]后的索引选项。请帮帮我。 Thankx guys

private void listView1_SelectedIndexChanged(object sender, EventArgs e) 
    { 
    textBox1.Text = people[listView1.SelectedItems[0].Index].Name; 
    } 
}

也许不完全准确，但工作。

public partial class Form1 : Form 
{ 
    List<People> people = new List<People>(); 

    public Form1() 
    { 
     InitializeComponent(); 
     people.Add(new People("Joe Montana")); 
     people.Add(new People("Alex Smith")); 
     people.Add(new People("Colin Kaepernick")); 

     foreach (People p in people) 
     { 
      this.listBox1.Items.Add(p.Name); 
     } 
    } 

    private void listBox1_SelectedIndexChanged(object sender, EventArgs e) 
    { 
     this.textBox1.Text = people[listBox1.SelectedIndices[0]].Name; 
    } 
} 

class People 
{ 
    public People(string Name) 
    { 
     this.Name = Name; 
    } 

    public string Name 
    { 
     get; 
     set; 
    } 
}
