C# Question About Object References

by Randy Lutcavich · in Technical Issues · 09/15/2009 (3:06 am) · 2 replies

I'm working with TX2D and am unable to use variables declared in one class in a whole other class. How do I access a variable in another class in C#?

For example I declared a variable in my game class:
int _testInt;

Then I even create a public accessor:


But then I get an error when I try to access it in another class like this:


_playerScore.Text = Convert.ToString(Game.testInt);


Error:

" An object reference is required for the non-static field, method, or property 'StarterGame2D.Game.testInt.get' "



I don't get it. Shouldn't using "Game.testInt" work?

			I'm not a C# person by any means, but if it's anything like Java, the cause of your problem is probably the same. So I'm going to take a stab in the dark and say that your problem is that your variable is not static. (Hence the error about a "non-static field, method, or property".) If "Game" is the name of your class and not an instance of a class, you will probably need to make your "testInt" variable and accessor methods static. Otherwise, a "testInt" variable will be added to every instance of the Game class, and it won't be accessible from the global Game class itself.

			The return type of Game is probably just the Microsoft.Xna.Framework.Game class, which does not have a "testInt" property. This is assuming you're running your code within a GameComponent.



Try this:



  int x = ((MyGameClass)Game).testInt;
