Decimal.ToUInt64 Method (Decimal)
.NET Framework (current version)
Converts the value of the specified Decimal to the equivalent 64-bit unsigned integer.
This API is not CLS-compliant.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- d
-
Type:
System.Decimal
The decimal number to convert.
| Exception | Condition |
|---|---|
| OverflowException | d is negative or greater than UInt64.MaxValue. |
The return value is the integral part of the decimal value; fractional digits are truncated.
You can also convert a Decimal value to an 64-bit unsigned integer by using the Explicit(Decimal to UInt64) assignment operator. Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.
The following example uses the ToUInt64 method to convert decimal numbers to UInt64 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 { ulong number = Decimal.ToUInt64(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 // 18446744073709551615.999 --> 18446744073709551615 // OverflowException: 18446744073709551616 // 9223372036854775807.999 --> 9223372036854775807 // 9223372036854775808 --> 9223372036854775808 // -0.999 --> 0 // OverflowException: -1 // OverflowException: -9223372036854775808.999 // OverflowException: -9223372036854775809
