    I'm currently developing a C# application and running into a NullReferenceException. It occurs when I try to access an object that may not be initialized. I’ve looked into using try-catch blocks, but I’m not entirely sure how to implement it effectively. Can anyone explain how to identify and resolve this error in C#? Any examples or best practices would be greatly appreciated!

      Without seeing any code we can only guess what may be wrong. You should run your code in the debugger to see where the error occurs. You can then work backwards to identify why the reference is null.
