My version is supported for across thread. The following is the source code:

public class ObservableCollectionEx<T> : ObservableCollection<T>
{
Dispatcher curerntDispatcher = (Application.Current as App).CurrentDispatcher;
public new void Add(T item)
{
try
{
if (curerntDispatcher != null)
{
curerntDispatcher.BeginInvoke(() =>
{
base.Add(item);
});
}
else

下面是c# code:
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using System.Threading;
using System.Windows.Navigation;
using System.Collections.ObjectModel;
using System.Windows.Threading;
namespace ObservableCollectionEx
{
public partial class MainPage : PhoneApplicationPage
{
private int temp = 0;
ObservableCollectionEx2 < SourceCode > testConnection = null;
public MainPage()
{
InitializeComponent();
(Application.Current as App).CurrentDispatcher = this.Dispatcher;
testConnection = new ObservableCollectionEx2 < SourceCode >();
}
protected override void OnNavigatedTo(NavigationEventArgs e)
{
(Application.Current as App).CurrentDispatcher = this.Dispatcher;
this.listBox1.ItemsSource = testConnection;
base.OnNavigatedTo(e);
}
private void button1_Click(object sender, RoutedEventArgs e)
{
Thread test1 = new Thread(DoWork);
test1.Start();
Thread test2 = new Thread(DoWork2);
test2.Start();
}
private void DoWork(object etest)
{
try
{
int tempCount = 0;
SourceCode code = new SourceCode();
code.FullName = temp.ToString();
temp++;
lock (App.LockObject)
{
testConnection.Add(code);
tempCount = testConnection.Count();
}
Thread.Sleep(100);
}
catch (Exception exce)
{
int i = 0;
}
}
private void DoWork2(object etest)
{
try
{
int tempCount = 0;
SourceCode code = new SourceCode();
code.FullName = temp.ToString();
temp++;
lock (App.LockObject)
{
testConnection.Add(code);
tempCount = testConnection.Count();
}
Thread.Sleep(100);
}
catch (Exception exce)
{
int i = 0;
}
}
}
}
下面是App的 C#文件:里面只需要加:
// public static ObservableCollectionEx2<SourceCode> testConnection = new ObservableCollectionEx2<SourceCode>();
public Dispatcher CurrentDispatcher { get; set; }
大功告成,不需要你手动刷一下UI,所有的UI均自动刷新。
