The type or namespace SelectElement could not be found in selenium c#

driver.FindElement(By.Id("inputUsername")).SendKeys("aca");
driver.FindElement(By.Id("inputPassword")).SendKeys("123");
driver.FindElement(By.TagName("button")).Click();

SelectElement oSelect = new SelectElement(driver.FindElement(By.Id("selectFilterbyUser")));
oSelect.selectByText("Alex");

Do anyone have solution for the problem that i had attach in the above? Try to use SelectElement but it displays:

The type or namespace `SelectElement` could not be found.

I tried to see the potential fixes, but it shows only three options which are

  • Generate class SelectElement in a new file
  • Generate class SelectElement
  • Generate nested class SelectElement

Does anyone know how to solve it?

Solution

  • Referring to a few previous posts it seems if you are using frameworks like nunittestadapter, NUnit.Framework, VS 2017 using the NuGet Manager sometimes there can be issues with the installation /configuration.

    SelectElement Class

    As per the documentation the SelectElement Class is pretty much available within OpenQA.Selenium.Support.UI Namespace which provides a convenience method for manipulating selections of options in an HTML select element.
