The following example uses the ToInt64 method to convert decimal numbers to Int64 values.
using System; class Example { public static void Main( ) { decimal[] values = { 123m, new Decimal(123000, 0, 0, false, 3), 123.999m, 18446744073709551615.999m, 18446744073709551616m, 9223372036854775807.999m, 9223372036854775808m, -0.999m, -1m, -9223372036854775808.999m, -9223372036854775809m }; foreach (var value in values) { try { long number = Decimal.ToInt64(value); Console.WriteLine("{0} --> {1}", value, number); } catch (OverflowException e) { Console.WriteLine("{0}: {1}", e.GetType().Name, value); } } } } // The example displays the following output: // 123 --> 123 // 123.000 --> 123 // 123.999 --> 123 // OverflowException: 18446744073709551615.999 // OverflowException: 18446744073709551616 // 9223372036854775807.999 --> 9223372036854775807 // OverflowException: 9223372036854775808 // -0.999 --> 0 // -1 --> -1 // -9223372036854775808.999 --> -9223372036854775808 // OverflowException: -9223372036854775809
