场景：
在一个工厂ERP管理系统中，有部分实体的界面需要显示相关联的其它信息，而这部分信息是弱连接的，需要调用WebAPI取回，传统的方式是一一取回，结果是用户感知的速度达不到要求。
使用BackgroundWorker，在后台取资料，取完资料后再显示，如果取资料的过程中，主实体已经变更了，或者已多次变更了，则等上次任务完成后，直接再取最后一次变更的资料，中间的直接丢弃，既加快了速度，也节省了资源。
实现思路：

先加入BackgroundWorker，（命名如：BackgroundWorker_ShowItem）。

再定义两个变量，用于保存要显示的主实体（或其关联键）

private T Item = null;
private T NextItem = null;

当需要显示一个主体的内容时，不直接显示，而是呼叫BackgroundWorker来处理

public void ShowItem(T item)
{
    if (BackgroundWorker_ShowItem.IsBusy)
    {
    this.NextItem = item;
    }
    else
    {
    this.Item = item;
    this.BackgroundWorker_ShowItem.RunWorkerAsync();
    }
}

private void BackgroundWorker_ShowItem_DoWork(object sender, DoWorkEventArgs e)
{
    this.ShowItem();
}

private void BackgroundWorker_ShowItem_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)
{
    if (this.NextItem != null)
    {
    var nextItem = this.NextItem;
    this.NextItem = null;
    this.ShowItem(nextItem);
    }
}

注意，当ShowItem()中有访问前端时，会报“线程间操作无效”的例外，需要使用Invoke，但不要在DoWork中将ShowItem()全部包含，而应该在ShowItem()中单独处理。否则达不到性能优化的效果。
