线程和WebBrowser控件 [英] Threading and webbrowser control

问题描述

我很新的线程。我启动一个线程是这样的：

I'm very new to threading. I start a thread like this:

Thread t_main;
t_main = new Thread(main_building_stuff);
t_main.Start();

和在某些时候，我想在main_building_stuff到虎视眈眈从网页的一些数据加载到。一个网页浏览器控制研究在主线程

And at some point, I want in the main_building_stuff to grap some data from an webpage that is loaded into an webbrowser controll in the main thread.

我这样做，随着这段代码：

I'm doing that with this piece of code:

HtmlElement lit = webBrowser1.Document.GetElementById("buildqueue");

但是，这将导致一个错误...
InvalidCastException的（指定的强制转换无效）

But that results in an error... InvalidCastException (specified cast is not valid)

什么是从web浏览器接收数据的正确方法？

What is the proper way to receive the data from the webbrowser?

推荐答案

有人说answerd的问题，给出了正确的答案。但由于某些原因，他删除了它，所以谢谢你，但我不记得你的名字......

Somebody that answerd the question, gave the right answer. But for some reason, he deleted it, so thank you, but i don't remember your name...

这是工作的一段代码：

webBrowser1.Invoke(new Action(() => {
                    HtmlElement lit = webBrowser1.Document.GetElementById("buildqueue");
                    result = "whatever";
                }));
