c# - 基于文本框值的列表框排序

Question

如何使用TextBox输入的值对ListBox项目进行排序。
火柴盒列表框项目显示在列表框的顶部
这是我的代码

XAML

<Grid>
    <TextBox HorizontalAlignment="Left" Height="23" Margin="67,39,0,0" TextWrapping="Wrap" Text="{Binding CustomerSort,UpdateSourceTrigger=PropertyChanged}" VerticalAlignment="Top" Width="120"/>
    <ListBox Margin="67,79,185,26" Background="LightYellow"
            DisplayMemberPath="Name" ItemsSource="{Binding CustomerColloction}"/>
</Grid>

C#代码

 public class Customers
{
    public String Name { get; set; }
    public Int32 Age { get; set; }
}

public class ViewModel
{
    public ViewModel()
    {
        CustomerColloction = new ObservableCollection<Customers>();
        CustomerColloction.Add(new Customers() { Name = "AAA", Age = 25 });
        CustomerColloction.Add(new Customers() { Name = "AA", Age = 25 });
        CustomerColloction.Add(new Customers() { Name = "BBB", Age = 26 });
        CustomerColloction.Add(new Customers() { Name = "BB", Age = 24 });
        CustomerColloction.Add(new Customers() { Name = "AAAA", Age = 13 });
        CustomerColloction.Add(new Customers() { Name = "BB", Age = 11 });
        CustomerColloction.Add(new Customers() { Name = "XYZ", Age = 44 });
    }
    public ObservableCollection<Customers> CustomerColloction { get; set; }

    private String _CustomerSort = String.Empty;
    public String CustomerSort
    {
        get
        {
            return _CustomerSort;
        }
        set
       {
            _CustomerSort = value;
            NotifyPropertyChanged("CustomerSort");
        }
    }

    public event PropertyChangedEventHandler PropertyChanged;
    protected void NotifyPropertyChanged(string propertyName)
    {
        if (this.PropertyChanged != null)
            this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
    }
}

我想得到的结果就像我们在文本框，显示排序项目表单列表框中输入AA一样

AA

AAA

AAAA

BB

BB

BBB

XYZ

Answer 1

设置组合框并设置下拉模式
最好对可观察的集合进行排序，并将其设置为ListBox CustomerColloction.OrderBy(q => q.Name).ToList();
