Converts the value of the specified Decimal to the equivalent 16-bit unsigned integer.

public:
 static System::UInt16 ToUInt16(System::Decimal value);

[System.CLSCompliant(false)]
public static ushort ToUInt16 (decimal value);

[<System.CLSCompliant(false)>]
static member ToUInt16 : decimal -> uint16

Public Shared Function ToUInt16 (value As Decimal) As UShort

Parameters

value

Decimal

The decimal number to convert.

Returns

UInt16

A 16-bit unsigned integer equivalent to the value of value.

Attributes

CLSCompliantAttribute

Exceptions

OverflowException

value is greater than UInt16.MaxValue or less than UInt16.MinValue.

Examples

The following example uses the ToUInt16 method to convert decimal numbers to UInt16 values.

using System;

class Example
{
   public static void Main( )
   {
      decimal[] values = { 123m, new Decimal(123000, 0, 0, false, 3),
                           123.999m, 65535.999m, 65536m,
                           32767.999m, 32768m, -0.999m,
                           -1m,  -32768.999m, -32769m };

      foreach (var value in values) {
         try {
            ushort number = Decimal.ToUInt16(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
//     65535.999 --> 65535

//     32767.999 --> 32767
//     32768 --> 32768
//     -0.999 --> 0
//     OverflowException: -1
//     OverflowException: -32768.999
//     OverflowException: -32769

   Public Sub Main()
      Dim values() As Decimal = { 123d, New Decimal(123000, 0, 0, false, 3),

         Try

Remarks

The return value is the integral part of the decimal value; fractional digits are truncated.

You can also convert a Decimal value to a 16-bit unsigned integer by using the Explicit assignment operator. Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.
