静态类中的NullReferenceException

Question

I have an asp.net application with a static "global" class. Inside of the static class I have a variable called user. When a user logs in a set that variable. Debugging through the log process. All my other static variable seems to be fine except two. I am not sure why I am getting 'GlobalVariables.User' threw an exception of type 'System.NullReferenceException'. Can anyone shed some light on this. Thanks

namespace GlobalClass

public static class GlobalVariables


public static User User { get; set; }

Answer 1

Its probably throwing because you didn't create an instance of User. One way to fix it is the following.

public static class GlobalVariables
{
   static GlobalVariables()
   {
       User = new User();
   }

   public static User User { get; set; }
}
