This is straight forward in C#. If you have used TryParse() function then you already know the answer.

using System;
namespace Demo
{
class Program
{
static void Main()
{
Console.WriteLine("Please type your input and press Enter key");
string strInput = Console.ReadLine();

int result = 0;
if (int.TryParse(strInput, out result))
{
Console.WriteLine("Your input {0} is a number", result);
}
else
{
Console.WriteLine("Your input {0} is NOT a number", strInput);
}
}
}
}

Sir, I have not faced any Interviews or not even given any written test, but I got a question on which you may record a video (if you wish) : How to create chainable methods? e.g. In LINQ we can do something like this : students.Where(s => s.Name == "John").Select(s =>s)
