排序自定义日期时间C＃

Question

我需要帮助按降序排序自定义日期时间在列表框中。

我的代码：

using System; 
using System.Collections.Generic; 
using System.ComponentModel; 
using System.Data; 
using System.Drawing; 
using System.Linq; 
using System.Text; 
using System.Threading.Tasks; 
using System.Windows.Forms; 

namespace WindowsFormsApplication6 
{ 
    public partial class Form2 : Form 
    { 

     public Form2() 
     { 
      InitializeComponent(); 
      dateTimePicker1.Format = DateTimePickerFormat.Custom; 
      dateTimePicker1.CustomFormat = "dd/mm/yyyy HH:mm"; 



     } 

     private void button1_Click(object sender, EventArgs e) 
     { 
      listBox1.Items.Add(textBox1.Text + ", " + Convert.ToDateTime(this.dateTimePicker1.Value).ToString("dd/mm/yyyy HH:mm")); 
     } 

     private void button2_Click(object sender, EventArgs e) 
     { 
      listBox1.Items.Remove(listBox1.SelectedItem); 
     } 

     private void dateTimePicker1_ValueChanged(object sender, EventArgs e) 
     { 

      dateTimePicker1.CustomFormat = "dd/mm/yyyy HH:mm"; 
     } 
    } 
} 

我添加从textBox1的日期和时间从DateTimePicker1文字，我想它根据时间自动排序。

谢谢！

我一直保持为目的List<string>：

试试这个：

List<string> lst; 

    public Form2() 
    { 
     InitializeComponent(); 
     dateTimePicker1.Format = DateTimePickerFormat.Custom; 
     dateTimePicker1.CustomFormat = "dd/mm/yyyy HH:mm";   
     lst = new List<string>(); 
    } 

    private void button2_Click(object sender, EventArgs e) 
    {    
     lst.Remove(listBox1.SelectedItem.ToString()); 
     BindList();    
    } 

    private void button1_Click(object sender, EventArgs e) 
    {   
     string s = textBox1.Text + ", " + Convert.ToDateTime(this.dateTimePicker1.Value).ToString("dd/mm/yyyy HH:mm"); 
     lst.Add(s); 
     BindList();   
    } 

    private void BindList() 
    { 
     lst = (lst.OrderByDescending(s => s.Substring(s.LastIndexOf(" "), s.Length - s.LastIndexOf(" ")))).ToList(); 
     listBox1.DataSource = lst; 
    }
