C# Operator (How It Works For Developers)

In C#, operators play a crucial role in performing various operations on variables and values. Whether you are a beginner or an experienced developer, a solid understanding of C# operators is fundamental for writing efficient and expressive code. In this comprehensive guide, we'll explore the different types of operators in C# and how they can be used in your programs. We will also see how to use these C# Operators with IronPDF.

1. Types of Operators in C#

1.1. Arithmetic Operators

Arithmetic operators in C# are used for basic mathematical operations. These include addition (+), subtraction (-), multiplication (*), division (/), and modulus (%). For arithmetic operators, operator precedence is similar to the commonly known BEDMAS or PEDMAS for mathematical operator precedence.

Let's delve into an example to understand how these operators work:

// Arithmetic Operators
int a = 10;
int b = 3;
int sum = a + b; // Adds the values of a and b
int difference = a - b; // Subtracts b from a
int product = a * b; // Multiplies a by b
int quotient = a / b; // Divides a by b (integer division)
int remainder = a % b; // Modulus operation; gives the remainder of a divided by b

Console.WriteLine("Arithmetic Operators:");
Console.WriteLine($"Sum: {sum}, Difference: {difference}, Product: {product}, Quotient: {quotient}, Remainder: {remainder}");
Console.WriteLine();

// Arithmetic Operators
int a = 10;
int b = 3;
int sum = a + b; // Adds the values of a and b
int difference = a - b; // Subtracts b from a
int product = a * b; // Multiplies a by b
int quotient = a / b; // Divides a by b (integer division)
int remainder = a % b; // Modulus operation; gives the remainder of a divided by b

Console.WriteLine("Arithmetic Operators:");
Console.WriteLine($"Sum: {sum}, Difference: {difference}, Product: {product}, Quotient: {quotient}, Remainder: {remainder}");
Console.WriteLine();

' Arithmetic Operators
Dim a As Integer = 10
Dim b As Integer = 3
Dim sum As Integer = a + b ' Adds the values of a and b
Dim difference As Integer = a - b ' Subtracts b from a
Dim product As Integer = a * b ' Multiplies a by b
Dim quotient As Integer = a \ b ' Divides a by b (integer division)
Dim remainder As Integer = a Mod b ' Modulus operation; gives the remainder of a divided by b

Console.WriteLine("Arithmetic Operators:")
Console.WriteLine($"Sum: {sum}, Difference: {difference}, Product: {product}, Quotient: {quotient}, Remainder: {remainder}")
Console.WriteLine()

1.2. Relational Operators

Relational operators are used to compare values and determine the relationship between them. Common relational operators in C# include greater than (>), less than (<), equal to (==), not equal to (!=), greater than or equal to (>=), and less than or equal to (<=).

// Relational Operators
bool isEqual = (a == b); // Checks if a is equal to b
bool notEqual = (a != b); // Checks if a is not equal to b
bool greaterThan = (a > b); // Checks if a is greater than b
bool lessThan = (a < b); // Checks if a is less than b
bool greaterOrEqual = (a >= b); // Checks if a is greater than or equal to b
bool lessOrEqual = (a <= b); // Checks if a is less than or equal to b

Console.WriteLine("Relational Operators:");
Console.WriteLine($"Equal: {isEqual}, Not Equal: {notEqual}, Greater Than: {greaterThan}, Less Than: {lessThan}, Greater or Equal: {greaterOrEqual}, Less or Equal: {lessOrEqual}");
Console.WriteLine();

// Relational Operators
bool isEqual = (a == b); // Checks if a is equal to b
bool notEqual = (a != b); // Checks if a is not equal to b
bool greaterThan = (a > b); // Checks if a is greater than b
bool lessThan = (a < b); // Checks if a is less than b
bool greaterOrEqual = (a >= b); // Checks if a is greater than or equal to b
bool lessOrEqual = (a <= b); // Checks if a is less than or equal to b

Console.WriteLine("Relational Operators:");
Console.WriteLine($"Equal: {isEqual}, Not Equal: {notEqual}, Greater Than: {greaterThan}, Less Than: {lessThan}, Greater or Equal: {greaterOrEqual}, Less or Equal: {lessOrEqual}");
Console.WriteLine();

' Relational Operators
Dim isEqual As Boolean = (a = b) ' Checks if a is equal to b
Dim notEqual As Boolean = (a <> b) ' Checks if a is not equal to b
Dim greaterThan As Boolean = (a > b) ' Checks if a is greater than b
Dim lessThan As Boolean = (a < b) ' Checks if a is less than b
Dim greaterOrEqual As Boolean = (a >= b) ' Checks if a is greater than or equal to b
Dim lessOrEqual As Boolean = (a <= b) ' Checks if a is less than or equal to b

Console.WriteLine("Relational Operators:")
Console.WriteLine($"Equal: {isEqual}, Not Equal: {notEqual}, Greater Than: {greaterThan}, Less Than: {lessThan}, Greater or Equal: {greaterOrEqual}, Less or Equal: {lessOrEqual}")
Console.WriteLine()

1.3. Logical Operators

Logical operators are used to perform logical operations on Boolean values. The common logical operations in C# are AND (&&), OR (||), and NOT (!). AND and OR are binary operators which have two operands, however, NOT is a unary operator which means it only affects one operand.

// Logical Operators
bool condition1 = true;
bool condition2 = false;
bool resultAnd = condition1 && condition2; // true if both conditions are true
bool resultOr = condition1 || condition2; // true if either condition is true
bool resultNot = !condition1; // inverts the Boolean value of condition1

Console.WriteLine("Logical Operators:");
Console.WriteLine($"AND: {resultAnd}, OR: {resultOr}, NOT: {resultNot}");
Console.WriteLine();

// Logical Operators
bool condition1 = true;
bool condition2 = false;
bool resultAnd = condition1 && condition2; // true if both conditions are true
bool resultOr = condition1 || condition2; // true if either condition is true
bool resultNot = !condition1; // inverts the Boolean value of condition1

Console.WriteLine("Logical Operators:");
Console.WriteLine($"AND: {resultAnd}, OR: {resultOr}, NOT: {resultNot}");
Console.WriteLine();

' Logical Operators
Dim condition1 As Boolean = True
Dim condition2 As Boolean = False
Dim resultAnd As Boolean = condition1 AndAlso condition2 ' true if both conditions are true
Dim resultOr As Boolean = condition1 OrElse condition2 ' true if either condition is true
Dim resultNot As Boolean = Not condition1 ' inverts the Boolean value of condition1

Console.WriteLine("Logical Operators:")
Console.WriteLine($"AND: {resultAnd}, OR: {resultOr}, NOT: {resultNot}")
Console.WriteLine()

1.4. Assignment Operators

Assignment operators are used to assign values to variables. The simple assignment operator is =. However, C# also provides compound assignment operators, such as +=, -=, *=, /=, and %=.

// Assignment Operators
int x = 5; // Assigns 5 to x
int y = 2; // Assigns 2 to y
x += y; // Increases x by the value of y
y *= 3; // Multiplies y by 3

Console.WriteLine("Assignment Operators:");
Console.WriteLine($"x after +=: {x}, y after *=: {y}");
Console.WriteLine();

// Assignment Operators
int x = 5; // Assigns 5 to x
int y = 2; // Assigns 2 to y
x += y; // Increases x by the value of y
y *= 3; // Multiplies y by 3

Console.WriteLine("Assignment Operators:");
Console.WriteLine($"x after +=: {x}, y after *=: {y}");
Console.WriteLine();

' Assignment Operators
Dim x As Integer = 5 ' Assigns 5 to x
Dim y As Integer = 2 ' Assigns 2 to y
x += y ' Increases x by the value of y
y *= 3 ' Multiplies y by 3

Console.WriteLine("Assignment Operators:")
Console.WriteLine($"x after +=: {x}, y after *=: {y}")
Console.WriteLine()

1.5. Bitwise Operators

Bitwise operators perform operations at the bit-level. Common bitwise operators include bitwise AND (&), bitwise OR (|), bitwise XOR (^), bitwise NOT or complement (~), left shift (<<), and right shift (>>).

// Bitwise Operators
int p = 5; // Binary: 0101
int q = 3; // Binary: 0011
int bitwiseAnd = p & q; // Binary AND operation
int bitwiseOr = p | q; // Binary OR operation
int bitwiseXor = p ^ q; // Binary XOR operation
int bitwiseNotP = ~p; // Binary NOT operation (complement)
int leftShift = p << 1; // Shift bits of p left by 1
int rightShift = p >> 1; // Shift bits of p right by 1

Console.WriteLine("Bitwise Operators:");
Console.WriteLine($"AND: {bitwiseAnd}, OR: {bitwiseOr}, XOR: {bitwiseXor}, NOT: {bitwiseNotP}, Left Shift: {leftShift}, Right Shift: {rightShift}");
Console.WriteLine();

// Bitwise Operators
int p = 5; // Binary: 0101
int q = 3; // Binary: 0011
int bitwiseAnd = p & q; // Binary AND operation
int bitwiseOr = p | q; // Binary OR operation
int bitwiseXor = p ^ q; // Binary XOR operation
int bitwiseNotP = ~p; // Binary NOT operation (complement)
int leftShift = p << 1; // Shift bits of p left by 1
int rightShift = p >> 1; // Shift bits of p right by 1

Console.WriteLine("Bitwise Operators:");
Console.WriteLine($"AND: {bitwiseAnd}, OR: {bitwiseOr}, XOR: {bitwiseXor}, NOT: {bitwiseNotP}, Left Shift: {leftShift}, Right Shift: {rightShift}");
Console.WriteLine();

' Bitwise Operators
Dim p As Integer = 5 ' Binary: 0101
Dim q As Integer = 3 ' Binary: 0011
Dim bitwiseAnd As Integer = p And q ' Binary AND operation
Dim bitwiseOr As Integer = p Or q ' Binary OR operation
Dim bitwiseXor As Integer = p Xor q ' Binary XOR operation
Dim bitwiseNotP As Integer = Not p ' Binary NOT operation (complement)
Dim leftShift As Integer = p << 1 ' Shift bits of p left by 1
Dim rightShift As Integer = p >> 1 ' Shift bits of p right by 1

Console.WriteLine("Bitwise Operators:")
Console.WriteLine($"AND: {bitwiseAnd}, OR: {bitwiseOr}, XOR: {bitwiseXor}, NOT: {bitwiseNotP}, Left Shift: {leftShift}, Right Shift: {rightShift}")
Console.WriteLine()

1.6. Conditional Operator (Ternary Operator)

The conditional operator (?:) is a shorthand way of expressing an if-else statement in a single line.

// Conditional (Ternary) Operator
int age = 20;
string result = (age >= 18) ? "Adult" : "Minor"; // Checks if age is 18 or more

Console.WriteLine("Conditional Operator:");
Console.WriteLine($"Result: {result}");
Console.WriteLine();

// Conditional (Ternary) Operator
int age = 20;
string result = (age >= 18) ? "Adult" : "Minor"; // Checks if age is 18 or more

Console.WriteLine("Conditional Operator:");
Console.WriteLine($"Result: {result}");
Console.WriteLine();

' Conditional (Ternary) Operator
Dim age As Integer = 20
Dim result As String = If(age >= 18, "Adult", "Minor") ' Checks if age is 18 or more

Console.WriteLine("Conditional Operator:")
Console.WriteLine($"Result: {result}")
Console.WriteLine()

In this example, the value of result will be "Adult" if age is greater than or equal to 18, and "Minor" otherwise.

1.7. Null-Coalescing Operator

The null-coalescing operator (??) is used to provide a default value for nullable types.

// Null-Coalescing Operator
int? nullableValue = null;
int resultCoalesce = nullableValue ?? 10; // Uses value 10 if nullableValue is null

Console.WriteLine("Null-Coalescing Operator:");
Console.WriteLine($"Result: {resultCoalesce}");

// Null-Coalescing Operator
int? nullableValue = null;
int resultCoalesce = nullableValue ?? 10; // Uses value 10 if nullableValue is null

Console.WriteLine("Null-Coalescing Operator:");
Console.WriteLine($"Result: {resultCoalesce}");

' Null-Coalescing Operator
Dim nullableValue? As Integer = Nothing
Dim resultCoalesce As Integer = If(nullableValue, 10) ' Uses value 10 if nullableValue is null

Console.WriteLine("Null-Coalescing Operator:")
Console.WriteLine($"Result: {resultCoalesce}")
