System.NullReferenceException: Object reference not set to …
Error message
System.NullReferenceException: Object reference not set to an instance of an object.
What broke
The code attempted to use an object that hasn't been initialized, leading to a NullReferenceException. This usually happens when you try to call a method or access a property on a null object.
Why it broke
It broke because the object you are trying to use has not been instantiated or assigned a value. This can occur if the object is expected to be created earlier in the code but wasn't due to a logic error or oversight.
How to fix
To fix this, ensure that the object is properly instantiated before you use it. You can add a null check before accessing its members or initialize the object where it is declared.
