How to programmatically verify test has failed using TechTalk.SpecFlow and C#?

Question

I want to do execute [AfterTestRun] attribute marked method after test fails of [Binding] attribute marked class. How can I achieve something like:

[Binding]
public class TestsRunner
{
   [AfterTestFails] // There is no such attribute
   public static void DoStuff()
   {

   }
}

or

[Binding]
public class TestsRunner
{
   [AfterTestRun]
   public static void DoStuff()
   {
        if(ScenarioContext.Current.TestHasFailed) // There is no such property
        {
            // Do stuff
        }  
   }
}

Answer 1

After reading some documentation here I have found the next solution:

[Binding]
public class TestsRunner
{
    [AfterScenario]
    public void TakeScreenShot()
    {
        if(ScenarioContext.Current.TestError != null)
        {
            WebBrowser.TakeScreenShot(); // Your custom browser take screenshot method 
        }
    }
}
