C# Return Values

C# Return Values

In C#, a return value is the data that a method sends back to the caller after it finishes execution. Methods that return values must specify a return type.

🔹 Basic Return Value

Calling the Method

🔹 Method Returning a String

🔹 Method Returning Boolean

🔹 Return Multiple Values (Using out)

🔹 Return Multiple Values (Tuple – Recommended)

🔹 Return an Array

🔹 Return Object

🔹 return Ends Method Execution

🔹 Void Methods (No Return)

🔹 Common Mistakes

❌ Missing return statement
❌ Returning wrong data type
❌ Code after return (unreachable)

🔹 Summary

✔ Methods can return values
✔ Return type must match value
✔ return stops execution
✔ Use tuples for multiple values
