It occurs when the application attempts to use an object that has not been instantiated, meaning it has not been given a value. This article will explain what this error message means, how it can be avoided, and how to troubleshoot it if encountered.
What is "Object Reference Not Set to an Instance of an Object"?
Object Reference Not Set to an Instance of an Object is an error message that is generated when the application attempts to use an object that has not been instantiated, meaning it has not been given a value.
