Comparison operators allow us to determine if two values are equal, different, greater, lesser, or greater/equal and lesser/equal.
The results of comparisons are boolean values (true or false), and they are fundamental for flow control logic.
The comparison operators in C# are:
| Operator | Name | Description |
|---|---|---|
== | Equality | Compares if two values are equal |
!= | Inequality | Compares if two values are different |
> | Greater than | Verifies if one value is greater than another |
< | Less than | Verifies if one value is less than another |
>= | Greater than or equal to | Verifies if one value is greater than or equal |
<= | Less than or equal to | Verifies if one value is less than or equal |
These operators are fundamental for decision-making in programs and are commonly used in control structures like conditionals or loops.

List of comparison operators
Equality (==)
The equality operator (==) is used to verify if two values are equal. It compares two values and returns true if they are equal, or false otherwise.
For example:
int a = 5;
int b = 5;
bool isEqual = (a == b); // true, since a and b are equal
Inequality (!=)
The inequality operator (!=) is used to verify if two values are not equal. It compares two values and returns true if they are different, or false otherwise.
For example:
int a = 5;
int b = 3;
bool isNotEqual = (a != b); // true, since a is not equal to b
Greater than (>)
The greater than operator (>) is used to verify if one value is greater than another.
int a = 10;
int b = 5;
bool isGreater = (a > b); // true, since a is greater than b
Less than (<)
The less than operator (<) is used to verify if one value is less than another.
int a = 3;
int b = 7;
bool isLess = (a < b); // true, since a is less than b
Greater than or equal to (>=)
The greater than or equal to operator (>=) is used to verify if one value is greater than or equal to another.
int a = 10;
int b = 10;
bool isGreaterOrEqual = (a >= b); // true, since a is equal to b
Less than or equal to (<=)
The less than or equal to operator (<=) is used to verify if one value is less than or equal to another.
int a = 5;
int b = 7;
bool isLessOrEqual = (a <= b); // true, since a is less than b
