Exception 'Element should have been select but was div' C# selenium

I'm getting an exception with a piece of code. My code is adding an item to a bag then I want to select the quantity of the item. When I click on the quantity on the drop down menu to select 2.
My code throws an exception on this line:
IWebElement Qty = webDriver.FindElement(By.Id("bagApp"));
SelectElementFromDropDown(Qty, "2");
Element should have been select but was div.
This piece of code is designed to click on the drop down menu.

}

You drop down is made of Divs and spans, Select class will not help you in this case.
You can try this code :
IList<IWebElement> options= webDriver.FindElements(By.CssSelector("li[class*='select2-results__option']"));
foreach (IWebElement element in options){
if(element.GetText().Equals("2")){
element.Click();
}
}
Note that before trying to select value from drop down , you have to click on down arrow button for that you can use this code :
webDriver.FindElement(By.CssSelector("span#select2-d2bx-container+span")).Click()
You should use explicit wait as you are moving to new page for this operation.

You can select the webelement as below
//Explicit wait is added to ensure that my bag item section is loaded successfully
WebDriverWait wait = new WebDriverWait(webDriver, TimeSpan.FromSeconds(5));
wait.Until(ExpectedConditions.ElementExists(By.XPath("//select[contains(#class,'bag-item-quantity')]")));
IWebElement qtyElement = webDriver.FindElement(By.XPath("//select[contains(#class,'bag-item-quantity')]"));
SelectElementFromDropDown(qtyElement,"2");

The error is occurring because you are using the SelectElement class on an HTML element that is not a SELECT, a DIV in this case.
In order to select the desired option, you need to click the dropdown to open it and then click the desired option from the dropdown. Since you will likely be selecting options more than once, it's a good idea to put the code to do that into a function.
public void SelectOption(string s)
{
new WebDriverWait(webDriver, TimeSpan.FromSeconds(5)).Until(ExpectedConditions.ElementToBeClickable(By.CssSelector($"span[title='{s}']"))).Click();
}
Then call it like
webDriver.FindElement(By.CssSelector("span.select2")).Click();
SelectOption("2");

Error message after successfully selenium login test to website

It's a simple selenium test to login in website. The test is passed if login with wrong username or password. But if you use your real's username and password test is fail, instead of that login is successfully. I believe that problem is in this code:
IWebElement ErrMessage = driver.FindElement(By.ClassName("validation-summary-errors"));
How to avoid this error check after successfulled login? Here is all code:
using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Logintest
{
public class MyFirstTest
{
IWebDriver driver = new OpenQA.Selenium.Chrome.ChromeDriver();
[Test]
public void myFirstTest()
{
driver.Navigate().GoToUrl("https://softuni.bg");
driver.FindElement(By.LinkText("Login")).Click();
IWebElement userName = driver.FindElement(By.Name("username"));
userName.Clear();
userName.SendKeys("username");
IWebElement userPass = driver.FindElement(By.Name("password"));
userPass.Clear();
userPass.SendKeys("password"); TimeSpan.FromSeconds(10);
driver.FindElement(By.LinkText("Ok")).Click();
driver.FindElement(By.XPath("/html/body/main/div[2]/div/div[2]/div[1]/form/input[2]")).Submit(); TimeSpan.FromSeconds(10);
IWebElement ErrMessage = driver.FindElement(By.ClassName("validation-summary-errors"));
Console.Write(ErrMessage.Text);
Assert.IsTrue(ErrMessage.Text.Contains("Wrong username or password"));
driver.Close();
driver.Quit();
}
}
}
This is test fail error:

Please try the following code for valid login,
public class MyFirstTest
{
IWebDriver driver = new OpenQA.Selenium.Chrome.ChromeDriver();
[Test]
public void myFirstTest()
{
driver.Navigate().GoToUrl("https://softuni.bg");
driver.FindElement(By.LinkText("Login")).Click();
//invalid scenario
IWebElement userName = driver.FindElement(By.Name("username"));
userName.Clear();
userName.SendKeys("username");
IWebElement userPass = driver.FindElement(By.Name("password"));
userPass.Clear();
userPass.SendKeys("password"); TimeSpan.FromSeconds(10);
driver.FindElement(By.LinkText("Ok")).Click();
driver.FindElement(By.XPath("/html/body/main/div[2]/div/div[2]/div[1]/form/input[2]")).Submit(); TimeSpan.FromSeconds(10);
IWebElement ErrMessage = driver.FindElement(By.ClassName("validation-summary-errors"));
Console.Write(ErrMessage.Text);
Assert.IsTrue(ErrMessage.Text.Contains("Wrong username or password"));
//valid secenario
userName.Clear();
userName.SendKeys("username");
userPass.Clear();
userPass.SendKeys("password");
driver.FindElement(By.XPath("//form/input[2]")).Submit();
TimeSpan.FromSeconds(10);
int count = driver.FindElements(By.ClassName("validation-summary-errors")).Count;
Assert.IsTrue(count==0);
driver.Close();
driver.Quit();
}
}

Selenium C# Can't find ID or Title

I manage to open a firefox browser, go to http://www.google.com/ search for "Bath Fitter". When i see a bunch of links, i want to in fact click on an item of the top menu provided by Google, Images. Images is located next to Map Videos News...
How can i have it click on Images?
Below is my code:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
namespace SeleniumHelloWorld
{
class Program
{
static void Main(string[] args)
{
IWebDriver driver = null;
try
{
driver = new FirefoxDriver();
driver.Navigate().GoToUrl("http://www.google.com/");
driver.Manage().Window.Maximize();
IWebElement searchInput = driver.FindElement(By.Id("gbqfq"));
searchInput.SendKeys("Bath Fitter");
searchInput.SendKeys(Keys.Enter);
searchInput.FindElement(By.Name("Images"));
searchInput.Click();
driver.Close();
}
catch (Exception e)
{
Console.WriteLine("Exception ****" + e.ToString());
}
}
}
}

More specifically you can also write your selector pointing from Top Navigation. This is the XPath.
.//*[#id='hdtb_msb']//a[.='Images']
try this;
driver.FindElement(By.XPath(".//*[#id='hdtb_msb']//a[.='Images']"));
EDIT:
Even though the selectors above were correct your code was not working because of the second page was taking too long to load. There you need to wait for the the element to be in ready state and an implicit wait is needed. Change the code in your try block and replace with mine and try
driver = new FirefoxDriver();
driver.Navigate().GoToUrl("http://www.google.com/");
driver.Manage().Window.Maximize();
IWebElement searchInput = driver.FindElement(By.Id("gbqfq"));
searchInput.SendKeys("Bath Fitter");
searchInput.SendKeys(Keys.Enter);
//this is the magic
driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(10));
By byImage = By.XPath(".//*[#id='top_nav']//a[.='Images']");
IWebElement imagElement =
new WebDriverWait(driver, TimeSpan.FromSeconds(10)).Until(ExpectedConditions.ElementExists(byImage));
imagElement.Click();

Try something like this...
IList<IWebElement> links = driver.FindElements(By.TagName("a"));
links.First(element => element.Text == "Images").Click();

How do I solve this error ?. Can I get any reference to add to the solution
I tried to add System.core , but it said that it is already present and was not accepting it
I did some research on Google but could not solve the problem and hence I am asking here .

Select element issue - webdriver - c#

I'm getting the below error while running in NUnit,
I'm finding an element and storing it in a variable, and while trying to select the element, i'm getting the error. Tried using in this way
IWebElement fromitem = WebDriver.FindElement(By.Id("from")); but same error persists.
Is there any way i can select the element?
Note : I verified the element id with firebug, there seems to be no problem with it.
The code below,
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;
using System.Threading;
using NUnit.Framework;
using OpenQA.Selenium;
using OpenQA.Selenium.Firefox;
using OpenQA.Selenium.Support.UI;
using OpenQA.Selenium.Remote;
using OpenQA.Selenium.Support.Events;
using OpenQA.Selenium.Support.PageObjects;
namespace SeleniumTests
{
[TestFixture]
public class Sel
{
public static IWebDriver WebDriver;
private String baseURL;
[SetUp]
public void SetupTest()
{
WebDriver = new FirefoxDriver();
baseURL = "http://www.x-rates.com/calculator.html";
}
[TearDown]
public void TeardownTest()
{
WebDriver.Quit();
}
[Test]
public void newtest()
{
WebDriver.Navigate().GoToUrl(baseURL + "/");
var fromitem = WebDriver.FindElement(By.Id("from"));
var toitem = WebDriver.FindElement(By.Id("to"));
var fromval = new SelectElement(fromitem); //Error occurs
var toval = new SelectElement(toitem);
fromval.SelectByText("USD - US Dollar");
toval.SelectByText("INR - Indian Rupee");
WebDriver.FindElement(By.LinkText("Currency Calculator")).Click();
var curval = WebDriver.FindElement(By.CssSelector("span.ccOutputRslt")).GetAttribute("Value");
var expectedValue = 61.456825;
Thread.Sleep(900);
Assert.AreEqual(expectedValue, curval.Trim());
}
}
}

The SelectElement class can only be used with actual HTML <select> elements. In the page you provided, the element in question is an <input> element, with functionality added through CSS and JavaScript to enable it to act like a drop-down list. As such, attempting to use it with the SelectElement class will throw an exception indicating that the element is not of the correct type.
The "File does not exist" error message is a red herring. It's only there because NUnit is trying to show you the line of source code where the exception is thrown, which is a part of the WebDriver source code. The exception thrown by that line of code should be displayed somewhere within NUnit, which should contain the appropriate informational message.
