what is integer 64 code example

Example 1: Int64

sbyte value1 = 124;
short value2 = 1618;
int value3 = Int32.MaxValue;

long number1 = value1;
long number2 = value2;
long number3 = value3;

Example 2: Int64

decimal[] values= { Decimal.MinValue, -1034.23m, -12m, 0m, 147m,
                    199.55m, 9214.16m, Decimal.MaxValue };
long result;

foreach (decimal value in values)
{
   try {
      result = Convert.ToInt64(value);
      Console.WriteLine("Converted the {0} value '{1}' to the {2} value {3}.",
                        value.GetType().Name, value,
                        result.GetType().Name, result);
   }
   catch (OverflowException) {
      Console.WriteLine("{0} is outside the range of the Int64 type.",
                        value);
   }   
}                                  
// The example displays the following output:
//    -79228162514264337593543950335 is outside the range of the Int64 type.
//    Converted the Decimal value '-1034.23' to the Int64 value -1034.
//    Converted the Decimal value '-12' to the Int64 value -12.
//    Converted the Decimal value '0' to the Int64 value 0.
//    Converted the Decimal value '147' to the Int64 value 147.
//    Converted the Decimal value '199.55' to the Int64 value 200.
//    Converted the Decimal value '9214.16' to the Int64 value 9214.
//    79228162514264337593543950335 is outside the range of the Int64 type.
