C# 9.0 Null Checking

April 12, 2022 C#damian

C# 9.0 added a lot of new features and enhanced others. Here we’re covering Pattern Matching, more specifically is null and is not null. Beginning with C# 7.0, the “is” operator was added to match an expression against a pattern, and with C# 9.0 the negation pattern was added to do a non-null check. Overview So why not just use “==” or “!=” operators? When you override the operators, your traditional null checks can behave differently. This is why it can be safer for you to use the newer pattern matching. The addition of null checking using, “is null“, though…

June 16, 2020 Technologydamian

“Which language should I learn?” is a frequent question I get asked by non-coders wanting to learn or ones who haven’t coded in a while. More often than not it’s because they have a great idea for something they want to make, or just want to automate some repetitious tasks. Perhaps, you just got out of high school or college with proficiency in Java or Python and want to make an app. Though they’re viable options, they are not always the best choice. My friend/co-worker would say C++… for everything. What? NO! There is no golden arrow for solving every…
