Conditional Statements in C#: if , if..else, Nested if, if-else-if

Learn how conditional statements work in C#, including if, if-else, nested if, and if-else-if ladders, with examples for each.

The Basic if Statement

The if statement executes a block of code only when a specified condition evaluates to true, forming the most basic building block of decision-making in C#.

The if-else Statement

Adding an else block allows your program to execute an alternative set of instructions when the original condition is false, covering both possible outcomes of a single condition.

Nested if Statements

Nested if statements place one if block inside another, allowing you to check additional conditions only after an outer condition has already been satisfied, useful for multi-layered decision logic.

The if-else-if Ladder

When you need to check multiple mutually exclusive conditions in sequence, an if-else-if ladder lets you test each condition in order and execute the first matching block, falling back to a final else if none match.
