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

            {
                //  Utils.e(exce.Message, exce);
            }
        }

         public  new  bool Remove(T item)
        {
             try
            {

                //  Utils.e(exce.Message, exce);
            }

             return  true;
        }

         public  new  void Clear()
        {
             try

                    });
                }
                 else
                {
                     base.Clear();
                }
            }
             catch (Exception exce)
            {
                //  Utils.e(exce.Message, exce);
            }
        }

         public  void RemoveAt( int index)
        {
             try
            {
                 if (curerntDispatcher !=  null)
                {
                    curerntDispatcher.BeginInvoke(() =>
                    {
                         base.RemoveAt(index);
                    });
                }
                 else
                {
                     base.RemoveAt(index);
                }
            }
             catch (Exception exce)
            {
                //  Utils.e(exce.Message, exce);
            }
        }

    }
}

下面是c# code:

 

using System;
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  readonly  object LockObject =  new  object();

        //  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。
