Decimal Implicit Conversion (UInt64 to Decimal)


Defines an implicit conversion of a 64-bit unsigned integer to a Decimal.

This API is not CLS-compliant.

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

public static implicit operator decimal (
	ulong value


Type: System.UInt64

The 64-bit unsigned integer to convert.

Return Value

Type: System.Decimal

The converted 64-bit unsigned 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 UInt64 values to Decimal numbers by using the UInt64 to Decimal conversion.

using System;

public class Example
    public static void Main()
        // Define an array of 64-bit unsigned integer values.
        ulong[] values = { ulong.MinValue, ulong.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:
//    0 (UInt64) --> 0 (Decimal)
//    18446744073709551615 (UInt64) --> 18446744073709551615 (Decimal)
//    281474976710655 (UInt64) --> 281474976710655 (Decimal)
//    123456789123456789 (UInt64) --> 123456789123456789 (Decimal)
//    1000000000000000 (UInt64) --> 1000000000000000 (Decimal)
