C# Method Overloading

C# Method Overloading

Method overloading in C# allows you to define multiple methods with the same name but with different parameters. The compiler decides which method to call based on the number, type, or order of parameters.

🔹 Basic Example

🔹 Overloading by Number of Parameters

🔹 Overloading by Parameter Order

🔹 Overloading with Different Data Types

🔹 Overloading vs Default Parameters

❌ Not allowed together if ambiguous:

⚠ Can cause confusion for the compiler.

🔹 Overloading and Return Type

❌ Return type alone cannot differentiate methods.

🔹 Overloading Constructors

🔹 Benefits of Method Overloading

✔ Improves readability
✔ Reusability
✔ Cleaner API design

🔹 Common Mistakes

❌ Same parameter list
❌ Confusing default parameters
❌ Overloading by return type

🔹 Summary

✔ Same method name, different parameters
✔ Compile-time polymorphism
✔ Cannot overload by return type alone
✔ Used in methods & constructors
