    <span style="padding-left:15px;">
    <input id="ctl00_ContentPlaceHolder1_Control1_stCat_8" type="checkbox" name="ctl00$ContentPlaceHolder1$AddControl1$cat$lstCat$8"/>
    <label for="ctl00_ContentPlaceHolder1_AddControl1_lstCat_8">Item 1</label>
    </span>
 </td>
</tr>

<tr>

Answer 1

这（或类似的东西）应该可以工作。

// WARNING: Untested code. Locator syntax may be
// slightly incorrect.
// Using C#, but other languages are similar.
// Assume driver is a valid IWebDriver instance.
ReadOnlyCollection<IWebElement> checkboxes = driver.FindElements(By.CssSelector("input[type='checkbox']"));
Console.WriteLine(checkboxes.Count);

Answer 2

public int CountCheckBoxes(IWebDriver driver)
    {
        int countedCheckBoxes = driver.FindElements(By.XPath("//input[@type='checkbox']")).Count;
        return countedCheckBoxes;
    }

Answer 3

    int countedCheckBoxes = driver.FindElements(By.CssSelector("input[type='checkbox']")).Count;
