Sort List Ascending and write to ListBox

Question

I would like to ask how to sort list by date time. I have class task

 public class tasks
{
    public string name { get; set; }
    /// <summary>
    /// Datum narození
    /// </summary>
    public DateTime expires { get; set; }
.
.
.
}

class data

 public class data
{
   public List<tasks> tsk = new List<tasks>();

public data()
    {
    }


 public void AddTask(string name, DateTime expires)
    {          
        tasks ts = new tasks(name, expires.Date);
        tsk.Add(ts);
    }

In Main program, I stores data in a List.

private data dt = new data();


dt.AddTask(textBox1.Text, dateTimePicker1.Value);

I would like to write data to the listbox sortAscending.

Answer 1

You can sort using LINQ and then place it into the list box using AddRange:

MyList m = new MyList();

m.Add("n1", DateTime.Now);
m.Add("n2", DateTime.Now.AddDays(1));
m.Add("n3", DateTime.Now.AddDays(-1));

var sortedList = from i in m
    orderby i.expires
    select i;
listBox1.Items.AddRange(sortedList.ToArray());

Answer 2

很难说出MyLIst是如何定义的，但是如果它是标准集合之一，则应该可以使用。

var result = MyList.OrderBy(x => x.expires).Select(x => x);
