5 Bad Practices to Avoid in C#

In this post, I want to give 5 little examples of bad practices in C# and what can be done instead to improve your code a little bit. If you are an intermediate C# developer, you should know these already, and if not you will learn them today.

Use Ternary Operator Instead of If Else

In most cases, it’s cleaner to use a Ternary Operator instead of an If Else condition because it will take less space and will make your code more readable.

if (age >= 18) { 
  return "You are an adult"; 
} 
else { 
  return "You are not an adult"; 
}

We can fit these 6 lines in one line like this:

return age >= 18 ? "You are an adult" : "You are not an adult";

Use Enum Instead of Hard-Coded Numbers

Whenever you can use an enum instead of a random number in your code, it will increase the readability of your code and reduce the possibility of making mistakes.

Don’t do this:

if(month == 2) { 
  days = 28; 
}

Instead, do this:

enum Months { 
  January = 1, 
  February = 2, 
  March = 3, 
  April = 4, 
  May = 5, 
  June = 6, 
  July = 7, 
  August = 8, 
  September = 9, 
  October = 10, 
  November = 11…
