C# BackgroundWorker 的使用、封装

示例代码：

PT_USER_INFO user = new PT_USER_INFO();
IList<TES_COMBAT_TASK> taskList = new List<TES_COMBAT_TASK>();

BackgroundWorker worker = new BackgroundWorker();
worker.DoWork += (s, e) =>
{
    user = HI.Get<Cache.ICacheService>().UserCache.GetCurrentUserInfo();
    taskList = HI.Get<ITaskService>().GetCombatTaskByUserIDUnfinished(user.ID.ToString());

};
worker.RunWorkerCompleted += (s, e) =>
{
    try
    {
        taskListView.ItemsSource = taskList;
    }
    catch { }
};
worker.RunWorkerAsync();

BackgroundWorker封装：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Linq;
using System.Text;

/**
 * 使用方法：

BackWork.Run(() => //DoWork
{

}, () => //RunWorkerCompleted
{

}, (ex) => //错误处理
{

});
