下面是缺失的部分 internal class MoveEntity { public int X; public int Y; public int sleep; public MoveEntity(int offset, int v, int sleep) { this.X = offset; this.Y = v; this.sleep = sleep; } }
public static class WebElementExtensions { public static IWebElement FindElementExt(this IWebDriver driver, By by, int timeoutInSeconds) { var wait = new DefaultWait<IWebDriver>(driver); wait.IgnoreExceptionTypes(typeof(StaleElementReferenceException), typeof(NoSuchElementException)); wait.Timeout = TimeSpan.FromSeconds(timeoutInSeconds); return wait.Until(d => driver.FindElement(by)); } }
到此程序可以完美运行了。。
