Question

我将项目添加到列表视图中，但我需要能够为每个项目运行一个线程以获取该项目的更多数据（需要更长时间才能获得）这只是我现在尝试的一个小样本，但由于某种原因，线程打印约5项左右的名称然后等待5秒

private void worker_DoWork(object sender, DoWorkEventArgs e)
{
    Console.WriteLine((string)e.Argument);
    Thread.Sleep(5000);
}

BackgroundWorker[] threadArray = new BackgroundWorker[items.Count];

int gIndex = -1;
foreach (Item gItem in items.Values)
{
    gIndex++;

    ItemDescription ID = getDescription(gItem.id);

    _ListViewAddRow(gIndex, ID.name, ID.url);

    threadArray[gIndex] = new BackgroundWorker();
    threadArray[gIndex].DoWork += new DoWorkEventHandler(worker_DoWork);
    threadArray[gIndex].RunWorkerAsync(ID.name);
}

正如@steve提到的那样     使用一个后台工作者。

     BackgroundWorker threadArray = new BackgroundWorker;
        List<string> list = new List<string>();

        foreach (Item gItem in items.Values)
        {//your code

                list.Add(ID.name); 
         }
    threadArray.RunWorkerAsync(list);

现在在dowork中将值转换为字符串列表     做工作方法

private void worker_DoWork(object sender, DoWorkEventArgs e)
{
     List<string> genericlist = e.Argument as List<string>;//cast
      for (int i = 0; i < genericlist.Count; i++) {
           Console.WriteLine(genericlist[i]);
           Thread.Sleep(5000);
       }

}

background循环中的backgroundWorker数组
