I often find myself using this great C# function: string.IsNullOrEmpty. It is the assured way to confirm whether a string is empty - null or otherwise. However, I often find myself wanting to know when it is not empty, so I wrote an string extension named HasValue.
Thus I have to write an if statement that reads more like this: I personally do not find this very readable because of the ! at the start of the if statement similar to how I like to organize my CASE Statement in SQL. Enter this little handy tidbit of code - a string extension - to improve readability: Inside the function HasValue contains the same if condition defined above. Now however, I can use the string extension method as follows: This of course matches the similar concept with nullable booleans or integers where they contain a built-in HasValue check. Thought I'd share as I previously stated Developers are authors and this makes your code much more readable. Published on Feb 5, 2019 Tags: ASP.NET MVC and Web API Tutorial
