c# - 使用 BackGroundWorker 运行 WatiN 打开 IE 浏览器

Question

我只是使用 WatIn，没有使用任何其他测试框架，例如 NUnit 或其他。

当我尝试运行 BackGroundWorker打开IE浏览器，出现错误

An exception of type 'System.Threading.ThreadStateException' occurred in WatiN.Core.dll but was not handled in user code

Additional information: The CurrentThread needs to have it's ApartmentState set to ApartmentState.STA to be able to automate Internet Explorer.

我在 stackoverflow 上阅读了一些线程，但是所有测试都因相同的错误而失败。

有人可以帮助我吗？

代码

BackgroundWorker _worker = new BackgroundWorker();
            _worker.WorkerReportsProgress = true;
            _worker.ProgressChanged += new ProgressChangedEventHandler(_worker_ProgressChanged);
            _worker.RunWorkerCompleted += new RunWorkerCompletedEventHandler(_worker_RunWorkerCompleted);            
            _worker.DoWork += (s, e2) =>
            {
                Loga(usuario, senha);
            };
            _worker.RunWorkerAsync();

    protected void Loga(string usuario, string senha)
    {            
        using (var browser = new IE("my page here"))
        {
           //Code here
        }
    }

Answer 1

您不能使用 Watin 启动多个线程。但你可以触发多个 IE 实例:

IE browser1 = new IE();
IE browser2 = new IE();

browser1.GoTo("http://www.google.com");
browser2.GoTo("http://www.yahoo.com");
