I cannot access radio button with selenium webdriver in c#

Question

I cannot access the radio button with chrom websriver in selnium. I am writing my code in c# here is the code I am using

driver.FindElement(By.CssSelector("input[name=eventCategoryID]")).Click();
driver.FindElement(By.CssSelector("input[value=11]")).Click();

for this radio button

Answer 1

You are missing some quotation marks. It should look like this:

driver.FindElement(By.CssSelector("input[name=\"eventCategoryID\"]")).Click();
driver.FindElement(By.CssSelector("input[value=\"11\"]")).Click();

The \\ escapes the following quotation mark so that it doesn't end the string.

Answer 2

您为什么不尝试XPath

 driver.FindElement(By.Xpath("")).Click();
