i Hate iFrames on Selenium C#

On my project i had to face with some elements which is inside a iframe.
So the steps are;

1. Click on a link (Which opens the iFrame).
2. Locate some elements inside the iFrame.
3. Close the iFrame by the close button on the iFrame.

Opening the iframe is Okey, Not a big deal.

This is my Iframe.

Issue happens when locating some elements on it.

I tried with several methods, But nothing works.

Finally i found that i have to switch to the iFrame 1st.

 IWebElement detailFrame = elm.Iframe;

 Driver.SwitchTo().Frame(detailFrame);

Then closing the iFrame.

I tried with pressing the escape key. -But NO luck.

Actions action = new Actions(Driver);

action.SendKeys(OpenQA.Selenium.Keys.Escape).Build().Perform();

Then tryed on clicking on some other area out of the iFrame.

and it works.

But before that i has to switch back to the default frame.

Actions action = new Actions(Driver);

Driver.SwitchTo().DefaultContent();

action.Click(elm.Summary).Build().Perform();

And im Done.
