WPF ListBox如何实现动态加载数据，并且滚动条自动下拉

一、绑定

ListBox绑定ViewModel中的string链表，注意不能用普通的List<string>，需要定义ObservableCollection<string>（如果用List<string>，界面刷新会有所延迟）

XAML（DataContext为viewModel）：

<ListBox x:Name="StatusList" ItemsSource="{Binding ListStatus}" />

ViewModel：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.ComponentModel;
using System.Collections.ObjectModel;
using System.Windows.Controls;
using System.IO;
using System.IO.Ports;
using System.Data;
using System.Windows.Threading;

namespace SPT
{
    public class ViewModel : INotifyPropertyChanged
    {

        public event PropertyChangedEventHandler PropertyChanged;
        public void OnPropertyChanged(PropertyChangedEventArgs e)
        {
            if (PropertyChanged != null)
                PropertyChanged(this, e);
        }

       
        private ObservableCollection<string> listStatus = new ObservableCollection<string> { };
        public ObservableCollection<string> ListStatus
        {
            get { return listStatus; }
            set
            {
                listStatus = value;
                OnPropertyChanged(new PropertyChangedEventArgs("ListStatus"));
            }
        }

    }
}
