Decimal Implicit Conversion (Int64 to Decimal)

Defines an explicit conversion of a 64-bit signed integer to a Decimal.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static implicit operator decimal (
	long value


Type: System.Int64

The 64-bit signed integer to convert.

Return Value

Type: System.Decimal
The converted 64-bit signed integer.

The overloads of the Implicit method define the types from which the compiler can automatically convert a Decimal value without an explicit casting operator (in C#) or a call to a conversion function (in Visual Basic). They are widening conversions that do not involve data loss and do not throw an OverflowException exception.

The following example converts Int64 values to Decimal numbers.

using System;

class Example
    public static void Main()
        // Define an array of 64-bit integer values. 
        long[] values = { long.MinValue, long.MaxValue, 
                          0xFFFFFFFFFFFF, 123456789123456789,
                          -1000000000000000 };
        // Convert each value to a Decimal. 
        foreach (var value in values) {
           Decimal decValue = value;
           Console.WriteLine("{0} ({1}) --> {2} ({3})", value,
                             value.GetType().Name, decValue,
// The example displays the following output: 
//    -9223372036854775808 (Int64) --> -9223372036854775808 (Decimal) 
//    9223372036854775807 (Int64) --> 9223372036854775807 (Decimal) 
//    281474976710655 (Int64) --> 281474976710655 (Decimal) 
//    123456789123456789 (Int64) --> 123456789123456789 (Decimal) 
//    -1000000000000000 (Int64) --> -1000000000000000 (Decimal)
