有没有人找到并行运行C#Selenium RC测试的方法？

 var buttons = driver.FindElementsByXPath("//button[@class='button']");
 Parallel.ForEach(buttons, b => b.Click());

 var clicks = 100;
 Parallel.For(0, clicks, i =>
 {
   driver.FindElement(By.XPath("//button[@class='button']")).Click();
   driver.Wait(TimeSpan.FromSeconds(5));
 });

 Task.Factory.StartNew(() =>
 {
   foreach (var button in buttons)
   {
      button.Click();
   }
 });
 driver.Wait(TimeSpan.FromSeconds(5));

 var clicks = 100;
 Task.Factory.StartNew(() =>
 {
   foreach (var button in buttons)
   {
      button.Click();
   }
 }).ContinueWith(t => driver.Wait(TimeSpan.FromSeconds(5)));
 Task.Delay(TimeSpan.FromSeconds(4));
