@jpoehls please can you explain how the code is working ? because I am seeing "Values" and "Keys" in the model state. What exactly "x" is referring to in the code ?

“x” is the KeyValuePair<> in the ModelStateDictionary. You can read the docs on that Type here: https://learn.microsoft.com/en-us/dotnet/api/system.web.mvc.modelstatedictionary?view=aspnet-mvc-5.2

@jpoehls I got you but why am I not able to see KeyValuePairs directly in the breakpoint. They are coming in the Values and Keys. This thing is confusing me. or will we loop according to things which is coming in "Result View" ?

You may be able to expand the Results View or Non-Public members to explore the pairs. I'm afraid I can't offer more specific help.

@jpoehls Thanks.
