The type or namespace name 'SelectElement' could not be found (are you missing a using directive or an assembly reference?)

I believe that you're missing assembly reference, SelectElement class is available at namespace OpenQA.Selenium.Support.UI . 我相信您缺少程序集引用，名称空间OpenQA.Selenium.Support.UI提供了SelectElement类。
Nuget: 的NuGet：
https://www.nuget.org/packages/Selenium.Support/3.141.0
Then it should works. 然后它应该工作。
using OpenQA.Selenium.Support.UI;
var comboBox = driver.FindElement(By.Name("search[active]"));
new SelectElement(comboBox).SelectByText("onlyactive");
EDIT: 编辑：
SelectByText providing the text of the option to be selected. SelectByText提供要选择的选项的文本。 If your combobox doesn't contains specified text value, then it will throw NoSuchElementException . 如果您的组合框不包含指定的文本值，则它将抛出NoSuchElementException 。
