Null pointer exceptions are no fun. You can avoid them and keep your code clean and maintainable by using these techniques to elegantly handle null values in C#.When working on applications in any programming language, you might have encountered null exceptions or null reference exceptions. A null pointer or a null reference is one that does not refer to a valid memory location or object. It is a problem that has plagued programmers as long as programmers have been writing programs. A null value is a special value that denotes non-availability of a valid value. A null value is one that, when assigned to an object, resets the value of a field or a variable in the object to no value, i.e. an empty value. You must handle null values in your application’s code to avoid null reference exceptions and unexpected behavior of your application at runtime. In this article, we’ll examine various ways to deal with null values in C#. To work with the code examples provided below, you should have Visual Studio 2022 installed in your system.When an object is not null, you can access its members (data members and methods) using the null-conditional operator (?.). If the object is null, the null-conditional operator will return null but will not throw a runtime exception when accessing the members of the object. Consider the following class.
