如何强制Web浏览器控件始终在同一窗口中打开网页？

一般来说,这种控制非常差,并且是故意由微软做出的.虽然Webrowser.Document.HtmlDocument和命名空间MSHTML周围有强大的工具集

它使用的一个例子是HtmlElement.DomElement

foreach(HtmlElement tag in webBrowser.Document.All)        
{
  switch (tag.TagName.ToUpper)
  {
    case "A":
    {
      tag.MouseUp += new HtmlElementEventHandler(link_MouseUp);
      break;
    }
  }
}

void link_MouseUp(object sender, HtmlElementEventArgs e)
{
  HtmlElement link = (HtmlElement)sender;
  mshtml.HTMLAnchorElementClass a = (mshtml.HTMLAnchorElementClass)link.DomElement;
  switch (e.MouseButtonsPressed)
  {
    case MouseButtons.Left:
    {
      if ((a.target != null && a.target.ToLower() == "_blank") ||
          e.ShiftKeyPressed ||
          e.MouseButtonsPressed == MouseButtons.Middle)
      {
        // add new tab
      }
      else
      {
        // open in current tab
      }
      break;
    }
    case MouseButtons.Right:
    {
      // show context menu
      break;
    }
  }
}
