using System;

class GFG {

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

        // taking a variable
        long var1 = -2382373544;

        if(var1.Equals(Int64.MinValue))
        {
            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:

Minimum Value is: -9223372036854775808
