C# | Int32 Struct

In C#, Int32 Struct represents 32-bit signed integer(also termed as int data type) starting from range -2,147,483,648 to +2,147,483,647. It also provides different types of method to perform various operations. You can perform the mathematical operation like addition, subtraction, multiplication, etc. on Int32 type. It supports bitwise operations like AND, OR, XOR, etc. It provides full support for standard and custom numeric format strings. You can call the methods of Convert and Math class to perform operations on Int32 value. Int32 struct inherits the ValueType class which inherits the Object class.

Fields

Fields	Description
MaxValue	This field is used to represent the largest possible value of an Int32. This field is constant.
MinValue	This field is used to represent the smallest possible value of Int32. This field is constant.

Example:

// C# program to illustrate the
// MaxValue and MinValue field
using System;

class GFG {

    // Main method
    static public void Main()
    {
        Int32 var1 = 34;
        Int32 var2 = 30;
        Int32 var3 = 59;

        // Get the Maximum and Minimum value
        // of Int32 type Using MaxValue and
        // MinValue field
        Console.WriteLine("Value 1: {0}", var1);
        Console.WriteLine("Value 2: {0}", var2);
        Console.WriteLine("Value 3: {0}", var3);

        Console.WriteLine("Maximum Value: {0}",
                               Int32.MaxValue);

        Console.WriteLine("Minimum Value: {0}",
                               Int32.MinValue);
    }
}

Output:

Value 1: 34
Value 2: 30
Value 3: 59
Maximum Value: 2147483647
Minimum Value: -2147483648

Methods

Method	Description
CompareTo()	This method is used to compare this instance to a specified object or Int32 and returns an indication of their relative values.
Equals()	This method is used to return a value indicating whether this instance is equal to a specified object or Int32.
GetHashCode()	This method is used to return the hash code for this instance.
GetTypeCode()	This method is used to return the TypeCode for value type Int32.
Parse()	This method is used to convert the string representation of a number to its 32-bit signed integer equivalent.
ToString()	This method is used to convert the numeric value of this instance to its equivalent string representation.
TryParse()	This method is used to convert the string representation of a number to its 32-bit signed integer equivalent. A return value indicates whether the operation succeeded.

Example 1:

// C# program to demonstrate the
// Int32.Equals(Object) Method
using System;
using System.Globalization;

class GFG {

    // Main Method
    public static void Main()
    {
        // Declaring and initializing value1
        int value1 = 70;

        // Declaring and initializing value2
        object value2 = 89;

        // using Equals(object) method
        bool status = value1.Equals(value2);

        // checking the status
        if (status)
            Console.WriteLine("{0} is equal to {1}",
                                value1, value2);
        else
            Console.WriteLine("{0} is not equal to {1}",
                            value1, value2);
    }
}

Output:

70 is not equal to 89

Example 2:

// C# program to illustrate the
// GetTypeCode() method
using System;

class GFG {

    // Main method
    static public void Main()
    {
        Int32 var1 = 100;
        Int32 var2 = 403;
        Int32 var3 = 503;

        // Get the type code of
        // all the variables
        // Using GetTypeCode() method
        Console.WriteLine("Get the type code of var1: {0}",
                                       var1.GetTypeCode());

        Console.WriteLine("Get the type code of var2: {0}",
                                       var2.GetTypeCode());

        Console.WriteLine("Get the type code of var3: {0}",
                                       var3.GetTypeCode());
    }
}

Output:

Get the type code of var1: Int32
Get the type code of var2: Int32
Get the type code of var3: Int32
