拖放在C＃中不起作用（Selenium Web Driver）

Question

是否有一些简单的拖放功能的工作代码？

1. 选择图片
2. 拖放到文件夹
3. 释放鼠标。

我在这里尝试了所有可能的代码示例，但在Visual Studio（C＃）中都不起作用。

WebElement firstdoc = driver.FindElement(By.XPath("//*@id='body']/section/div/div[5]/ul/li[1]")); 
IWebElement Fundingfolder = driver.FindElement(By.XPath("//*[@id='body']/section/div/div[3]/div[1]/div[1]/di‌​v[1]/div[1]")); 
IWebElement secdoc = driver.FindElement(By.XPath("//*[@id='body']/section/div/div[5]/ul/li[1]/div[1]"‌​)); 
IWebElement Incomefolder = driver.FindElement(By.XPath("//*[@id='body']/section/div/div[3]/div[1]/div[1]/di‌​v[2]/div[1]"));


Actions Builder = new Actions(driver); 
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10)); 
Builder.MoveToElement(firstdoc); 
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(20)); 
Builder.ClickAndHold(firstdoc); 
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(20)); 
Builder.DragAndDrop(firstdoc, Fundingfolder); 
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(20)); 
Builder.Release(Fundingfolder).Perform(); 
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(20));

Answer 1

IWebElement drag = driver.FindElement(By.Id(id));

IWebElement drop = driver.FindElement(By.XPath(xPath));

(new Actions(driver)).ClickAndHold(drag).MoveToElement(drop).DragAndDrop(drag, drop).Perform();
