Int64.MaxValue Field in C# with Examples

The MaxValue field or property of Int64 Struct is used to represent the maximum value of Int64. The value of this field is constant means that the user cannot change the value of this field. The value of this field is 9223372036854775807. Its hexadecimal value is 0x7FFFFFFFFFFFFFFF.

Syntax:

public const long MaxValue = 9223372036854775807;

Return Value: This field always returns 9223372036854775807.

Example:

// C# program to illustrate the
// Int64.MaxValue Field
using System;

class GFG {

    // Main Method
    static public void Main()
    {
        // display the Maximum
        // value of Int64 struct
        Console.WriteLine("Maximum Value is: "+
                            Int64.MaxValue);

        // taking a variable
        long var1 = 93422337368375807;

        if(var1.Equals(Int64.MaxValue))
        {
            Console.WriteLine("Equal..!!");
            Console.WriteLine("Type of var1 is: {0}",
                                var1.GetTypeCode());
        }
        else
        {
            Console.WriteLine("Not equal..!!");
            Console.WriteLine("Type of var1 is: {0}",
                                var1.GetTypeCode());
        }
    }
}

Output:

Maximum Value is: 9223372036854775807
Not equal..!!
Type of var1 is: Int64
