The Int32 type in C# represents a 32-bit signed integer. To convert an Int32 value to its string representation, you can use the ToString() method. This method converts the numeric value into a readable string format. Syntax Following is the syntax for converting an Int32 to string using ToString() − int number = value; string result = number.ToString(); You can also use format specifiers with ToString() − string result = number.ToString("format"); Using ToString() Method Basic Conversion Example The simplest way to convert an Int32 to string is using ...

Aggregation in C# represents a has-a relationship between objects where one class contains or uses another class. In aggregation, the contained object can exist independently of the container object, making it a weak association. For example, an Employee has an Address, and a Department has multiple Employees. The key characteristic of aggregation is that when the container object is destroyed, the contained objects continue to exist independently. Syntax Following is the syntax for implementing aggregation in C# − public class ContainerClass { private ContainedClass containedObject; ... Read More
The System.Math class in C# provides methods and properties to perform mathematical operations, trigonometric calculations, logarithmic functions, and other common mathematical computations. All methods in the Math class are static, meaning you can call them directly without creating an instance. Common Mathematical Methods The following table shows some of the most commonly used methods in the Math class − Method Description Abs() Returns the absolute value of a number (works with decimal, double, int, etc.) Ceiling() Returns the smallest integer greater than or equal to the specified number ...

A substring is any contiguous sequence of characters within a string. In C#, you can generate all possible substrings of a given string using the Substring() method with nested loops to iterate through different starting positions and lengths. Syntax The Substring() method extracts a portion of a string − string.Substring(startIndex, length) To generate all substrings, use nested loops − for (int length = 1; length
The Console.WindowWidth property gets or sets the width of the console window measured in columns. This property is useful for creating console applications that need to adapt their output formatting based on the current window dimensions. Syntax Following is the syntax to get the console window width − int width = Console.WindowWidth; Following is the syntax to set the console window width − Console.WindowWidth = value; Return Value The property returns an int representing the width of the console window in columns. When setting the property, the value must ... Read More
Basic arithmetic operators in C# allow you to perform mathematical calculations such as addition, subtraction, multiplication, division, and modulus operations. These operators work with numeric data types and form the foundation of mathematical computations in C#. Arithmetic Operators Operator Description + Adds two operands - Subtracts the second operand from the first * Multiplies both operands / Divides the numerator by denominator % Modulus operator returns the remainder after division ++ Increment operator increases integer value by one -- ...

A copy constructor in C# creates a new object by copying variables from another object of the same class. It provides a way to initialize a new object with the values of an existing object, creating a separate copy rather than a reference to the original object. Syntax Following is the syntax for creating a copy constructor − public ClassName(ClassName obj) { this.field1 = obj.field1; this.field2 = obj.field2; // copy other fields } How Copy Constructor Works A copy constructor takes an object of ...

The Convert.ChangeType() method in C# converts a value to a specified type. It returns an object of the target type whose value is equivalent to the original object. This method is particularly useful when you need to perform type conversions at runtime or when working with generic code. Syntax Following is the syntax for the Convert.ChangeType() method − public static object ChangeType(object value, Type conversionType) public static object ChangeType(object value, TypeCode typeCode) Parameters value − The object to convert. conversionType − The target Type to convert to. typeCode − The TypeCode representing ... Read More
The Convert.ToBoolean method in C# converts a specified value to an equivalent Boolean value. This method follows specific rules depending on the input type − numeric types return false if zero, true otherwise; string values are parsed based on their content. Syntax Following is the syntax for the Convert.ToBoolean method − public static bool ToBoolean(object value); public static bool ToBoolean(string value); public static bool ToBoolean(int value); public static bool ToBoolean(double value); // Other overloads for different data types Parameters value − The value to convert to a Boolean. Can be a ... Read More
The Convert.ToByte method in C# converts a specified value to an 8-bit unsigned integer (byte). A byte can hold values from 0 to 255, making it useful for representing small integers, ASCII characters, and binary data. This method provides a safe way to convert various data types to byte values, with built-in overflow checking that throws an OverflowException if the value is outside the valid byte range. Syntax Following are the common overloads of the Convert.ToByte method − Convert.ToByte(object value) Convert.ToByte(string value) Convert.ToByte(char value) Convert.ToByte(int value) Convert.ToByte(double value) Parameters value − ...
