Consider this code: int age = 25; short newAge = 25; Console.WriteLine(age == newAge); //true Console.WriteLine(newAge.Equals(age)); //false Console.ReadLine(); Both int and short are primitive types, but a comparison with == returns true and a comparison with Equals returns false. Why? Short answer: Equality is complicated. Detailed answer: Primitives types override the base object.Equals(object) and return true if the boxed object is of the same type and value. (Note that it will also work for nullable types; non-null nullable types always box to an instance of the underlying type.) Since

I'm comparing strings with comparison operators. I needs some short of explanations for the below two comparisons and their result. if('ai' > 'i') { echo 'Yes'; } else { echo 'No'; } output: No Why do these output this way? if('ia' > 'i') { echo 'Yes'; } else { echo 'No'; } Output: Yes Again, why? Maybe I forgot some basics, but I really need some explanation of these comparison examples to understand this output. coderabbi PHP will compare alpha strings using the greater than and less than comparison operators based upon alphabetical order. In the first example, ai comes before i in

I am using MVC3 and I want to have LogIn form and Register form on the same page. To achieve that I built LogInRegisterViewModel as following: public class LogInRegisterViewModel { public LogInViewModel LogIn { get; set; } public RegisterViewModel Register { get; set; } } It gives me what I want (two forms on the same screen) and posts the data to correct controllers and returns and displays errors for forms (if any). The only problem I have is with CompareAttribute that I have above ConfirmPassword property in my RegisterViewModel: public class RegisterViewModel { [Required] [Display(Name =
