C# selenium element screenshot in iframe

Question

I am running the following code to get a logo screenshot but as it seems that location and size of element doesn't work when the element is in iframe. How element screenshot works in iframe ?

using System;
using System.Drawing;
using System.IO;
using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

var _driver = new ChromeDriver();
_driver.Navigate().GoToUrl("https://www.w3schools.com/tags/tryit.asp?filename=tryhtml_iframe");
_driver.SwitchTo().Frame("iframeResult");
_driver.SwitchTo().Frame(_driver.FindElement(OpenQA.Selenium.By.XPath("//iframe[@src='https://www.w3schools.com']")));
IWebElement element = _driver.FindElement(OpenQA.Selenium.By.XPath("//a[@class='w3schools-logo']"));
Console.WriteLine(element.Location); //Return 0
Console.WriteLine(element.Size); //Return 0
Screenshot sc = ((ITakesScreenshot)_driver).GetScreenshot();
using (var img = Image.FromStream(new MemoryStream(sc.AsByteArray)) as Bitmap)
{
 img?.Clone(new Rectangle(element.Location, element.Size), img.PixelFormat).Save(@"C:\test.jpg", System.Drawing.Imaging.ImageFormat.Jpeg);
}

I have found a solution

new Actions(_driver).MoveToElement(element).Build().Perform();
Thread.Sleep(1000);
var sc = ((ITakesScreenshot) _driver).GetScreenshot();
var remoteWebElement = element as RemoteWebElement;
using (var img = Image.FromStream(new MemoryStream(sc.AsByteArray)) as Bitmap)
{
if (remoteWebElement != null)
 img?.Clone(new Rectangle(remoteWebElement.LocationOnScreenOnceScrolledIntoView,remoteWebElement.Size), img.PixelFormat).Save(file, ImageFormat.Jpeg);
}
