Numeric Datatype Method and Properties:
ToString(): Converts an integer to its string representation.
Example
int number = 42;
string numberAsString = number.ToString(); // “42”
Parse(): Converts a string containing an integer to an actual integer.
Example
string numberAsString = “123”;
int parsedNumber = int.Parse(numberAsString); // 123
Math Operations: You can perform various mathematical operations like addition, subtraction, multiplication, and division using standard operators like +, -, *, and /.
Example
int result = 10 + 5; // Addition
int difference = 20 – 8; // Subtraction
int product = 6 * 4; // Multiplication
int quotient = 16 / 2; // Division
Properties
MaxValue: Gets the maximum value that can be held by an integer of that type.
Example
int max = int.MaxValue; // 2147483647
MinValue: Gets the minimum value that can be held by an integer of that type
Example
int min = int.MinValue; // -2147483648
Size: Returns the number of bytes used to store the integer.
Example
int size = sizeof(int); // 4 bytes
These are some of the commonly used methods and properties when working with integer types in C#. They allow you to perform operations on integers and retrieve information about their limits and size.
C# int.Parse Vs int.TryParse Method
- Convert a string representation of number to an integer,using the int.TryParse and intParse method in C#.
static void Main() { int res; string myStr = “120”; res = int.Parse(myStr); Console.WriteLine(“String is a numeric representation: “+res); } | static void Main() { bool res; int a; string myStr = “120”; res = int.TryParse(myStr, out a); Console.WriteLine(“String is a numeric representation: “+res); } |
Output String is a numeric representation: 120 | Output String is a numeric representation: True |
If the string cannot be converted, then the int.TryParse method returns false i.e. a Boolean
- value, whereas int.Parse returns an exception.
Programs To Practice
- Practice variable declaration and initialization.
- C# Program to find the minimum value and maximum value of All integer data types.
- Practice Printing message on console using Interpolation, Concatenation and Place holder.
- Practice the Method and properties of Integer, byte, short, long data types.
