C＃我可以添加值与backgroundwork线程列表框？ [英] C# Can I add values to a listbox with a backgroundwork thread?

问题描述

我希望我的后台工作，以项目添加到一个列表框，它调试但列表框不显示值时，会出现这样做。我怀疑这是事做添加项目，而后台工作线程里面，我还需要在 backgroundWorker1_RunWorkerCompleted 这些添加到一个数组，然后填充从数组列表框中？

I want my background worker to add items to a list box, it appears to do so when debugging but the listbox doesn't show the values. I suspect this is something to do with adding items whilst inside the background worker thread, do I need to add these to an array and then populate the list box from the array during backgroundWorker1_RunWorkerCompleted?

感谢您的帮助。

推荐答案

您可以使用调用像这样的：

You can use Invoke like this:

private void AddToListBox(object oo)
{
    Invoke(new MethodInvoker(
                   delegate { listBox.Items.Add(oo); }
                   ));
}
