C# Beginner Coding Tips

📌 Stay organized by creating one class per file. Nested classes and structs are an exception.
📌 Use Pascal and Camel Case naming conventions: DoSomethingMethod() and localVariableName.
📌 Method names should inform the programmer exactly what they are doing: DashForward() and FireWeapon()
📌 Use arrays for sets of data that do not need to change in size.
📌 Use List<> for sets of data that change over time. Understand that methods like Insert() can have poor performance.
📌 Opt for a HashSet<> when you need an ordered set of keys.
📌 Dictionary<> should only be used when you have both key/value pairs.
📌 Strings are immutable, which means every string every created will allocate its own set of memory.
📌 StringBuilder should be used when concatenating strings in a loop.
📌 string.IsNullOrEmpty should be used instead of a null check.
📌 Use string interpolation to concatenate short strings: string message = $"Hello {nameList[n].FirstName}"; 📌 Shorten your conditional statements by using the operator ?
📌 Higher-level methods most likely mean less performance. LINQ provides powerful functionality like Where() and Select() which can be slow.
📌 Minimize Garbage Collection. Know which calls allocate on the heap; you probably don't want them called in tightly looped operations.
