Int32.MaxValue Field in C# with Examples

The MaxValue field or property of Int32 Struct is used to represent the maximum value of Int32. The value of this field is constant means that the user cannot change the value of this field. The value of this field is 2147483647. Its hexadecimal value is 0x7FFFFFFF. It is used to avoid the OverflowException while converting to an Int32 value.

Syntax:

public const int MaxValue = 2147483647;

Return Value: This field always returns 2147483647.

Example:

// C# program to illustrate the
// Int32.MaxValue field
using System;

class GFG {

    // Main Method
    static public void Main()
    {
        // display the Maximum value
        // of Int32 struct
        Console.WriteLine("Maximum Value is: "+
                                Int32.MaxValue);

        // Taking an array of long i.e Int64 data type
        long[]num = {347, 49458, 345348534650436656};

        // taking variable of Int32 type
        int mynum;

        foreach(long n in num){

            if(n >= Int32.MinValue && n <= Int32.MaxValue)
            {

                // using the method of Convert class
                mynum = Convert.ToInt32(n);

                Console.WriteLine("Conversion is Possible.");
            }
            else
            {
                Console.WriteLine("Not Possible");
            }
        }

    }
}

Output:

Maximum Value is: 2147483647
Conversion is Possible.
Conversion is Possible.
Not Possible
