C# 如何获取a<；ul>；自动列出并选择一个随机选项

我无法选择标记列表中的项目，

中列出的所有选项。基本上，我需要知道项目的数量，并选择一个（任何）。当前代码无法选择do to，我无法找到正确的索引，我必须手动搜索正确的索引

我尝试对列表中的每个元素使用

如何搜索索引和显示的选项：

foreach (var a in nameoflist)
            {
                Console.WriteLine("ddm" + a.Text);
            }

如何选择列表中的项目：

List<IWebElement> dropDownMenu = driver.FindElements(By.ClassName("dropdown-menu"));
IList<IWebElement> selectdomain = dropDownMenu[0].FindElements(By.TagName("li"));
selectdomain[0].Click();

列表下拉菜单=driver.FindElements（By.ClassName（“下拉菜单”）；
IList selectdomain=dropDownMenu[0]。FindElements（按.TagName（“li”））；
选择域[0]。单击（）；

我总是收到“索引超出范围”错误，我必须手动搜索有效的索引。如何自动选择任何选项？

我从未使用过selenium，但您可以尝试以下操作：

// Get ul.dropdown-menu > li
List<WebElement> dropdownMenuItems = driver.findElements(By.xpath("//ul[@class='dropdown-menu']/li")); 

// Get Quantity
int quantity = dropdownMenuItems.Count;

// Create instance of random
Random rnd = new Random();

// Get a random index between 0 and the max being list length
int randomIndex = rnd.Next(quantity); 

// Get the list item from the random index
var randomListItem = dropdownMenuItems[randomIndex];

// Click the element
randomListItem.Click();


// Optiona: Loop through items
foreach (var listItem in dropdownMenuItems)
{
    Console.WriteLine("ddm" listItem a.Text);
}

//获取ul.dropdown-menu>li
List-dropdownMenuItems=driver.findElements（By.xpath（“//ul[@class='dropdown-menu']/li”）；
//获取数量
int quantity=dropdownMenuItems.Count；
//创建实例
IList<IWebElement> selectdomain = dropDownMenu[0].FindElements(By.TagName("li"));

var count = selectdomain.Count();
if (count > 0){
    selectdomain[0].Click();
}
