问题描述

我从此循环中获得索引超出范围".但是我需要使用循环发现的新元素，我该怎么做?请帮助解决问题

I am getting "index out of range" from this loop. But I need to use new elements that loop founds, how do I do that? Please help to fix the problem

int linkCount = driver.FindElements(By.CssSelector("a[href]")).Count;
string[] links = new string[linkCount];

for (int i = 0; i < linkCount; i++)
{
    List<IWebElement> linksToClick = driver.FindElements(By.CssSelector("a[href]")).ToList();
    links[i] = linksToClick[i].GetAttribute("href");
}

推荐答案

您可以重写代码以绕过for循环:

You can rewrite your code to bypass the for loop:

string[] links = driver.FindElements(By.CssSelector("a[href]")).Select(l => l.GetAttribute("href")).ToArray();

这还应该避免索引超出范围的问题，并减少您必须编写的代码量.

This should also avoid the index out of range problem, and cut down the amount of code you have to write.
