使用自定义控件排序列表

Question

我想对包含自定义控件的列表进行排序。该列表有一个 listboxitem 列表，里面有一个复选框，复选框里面有一个文本块。

List<ListBoxItem> listboxItem =new List<ListBoxItem>();

Some code that add the control into listboxItem with for loop
{
ListBoxItem lbi = new ListBoxItem();
CheckBox chkBox = new CheckBox();
TextBlock txtBlock = new TextBlock();
txtBlock.Text = sometext;
chkBox.Content = txtBlock;
lbi.Content = chkBox;
listBoxItems.Add(lbi); 
}

listboxItems.Sort();

而且我已经实现了 IComparable 接口

public int CompareTo(Object obj)
    {
        if (obj == null) return 1;

        List<ListBoxItem> listBoxItems = obj as List<ListBoxItem>;

        for (int i = 0; i < listBoxItems.Count; i++)
        {
            if (i < listBoxItems.Count)
            {
                ListBoxItem listBoxItem = listBoxItems[i];
                ListBoxItem lbi = this.listBoxItems[i];
                CheckBox checkBox = listBoxItem.Content as CheckBox;
                CheckBox chk = lbi.Content as CheckBox;
                TextBlock textBlock = checkBox.Content as TextBlock;
                TextBlock txt = chk.Content as TextBlock;

                return string.Compare(txt.Text, textBlock.Text);
            }
        }
        return 0;
    }

它仍然给我错误，需要实现 Icomparable。不确定它是否正确实现或使用，对于这个实现我来说很新 @.@

Answer 1

刚刚发现可以使用 Linq 和 Tag 来摆脱 IComparable。

编辑代码：

Some code that add the control into listboxItem with for loop
{
ListBoxItem lbi = new ListBoxItem();
CheckBox chkBox = new CheckBox();
TextBlock txtBlock = new TextBlock();
txtBlock.Text = sometext;
chkBox.Content = txtBlock;
lbi.Content = chkBox;
lbi.Tag = sometext;
listBoxItems.Add(lbi); 
}

listBoxItems = listBoxItems.OrderBy(x => x.Tag).ToList();

然后，列表将按字母顺序完美排序。
