{
  InitializeComponent();

  listBox1.Items.Add("ccc");
  listBox1.Items.Add("aaa");
  listBox1.Items.Add("bbb");
}
private void btnSort_Click(object sender, RoutedEventArgs e)
{
  listBox1.Items.SortDescriptions.Add(
  new System.ComponentModel.SortDescription("Content",
       System.ComponentModel.ListSortDirection.Ascending));
}

更新： 好吧，我只是跟着文章排序一个WPF列表框项目

Update: Well, I simply followed the article "Sorting a WPF ListBox Items"

那么，什么是我感到属性内容和排序顺序中是财产的内容，我不知道（试图将其更改为任意的FFF，而不是内容已经得到了相同的，在第2个截图，结果？

So, what is the order by which I am sorting by a property "Content" and where is that property "Content", I wonder (tried to change it to arbitrary "fff" instead of "Content" having gotten the same, as in 2nd screenshot, results?

推荐答案

既然你排序字符串列表，并不表明属性名称（SortDescription的第一个参数）：

Since you're sorting a list of strings, don't indicate a property name (first parameter of SortDescription):

listBox1.Items.SortDescriptions.Add(
            new System.ComponentModel.SortDescription("",
            System.ComponentModel.ListSortDirection.Ascending));
