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

public:
 static short ToInt16(System::Decimal value);
public static short ToInt16(decimal value);
static member ToInt16 : decimal -> int16
Public Shared Function ToInt16 (value As Decimal) As Short

Parameters

value
Decimal

The decimal number to convert.

Returns

Int16

A 16-bit signed integer equivalent to value.

Exceptions

OverflowException

value is less than Int16.MinValue or greater than Int16.MaxValue.

Examples

The following example uses the ToInt16 method to convert decimal numbers to Int16 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 {
            short number = Decimal.ToInt16(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: 65535.999
//     OverflowException: 65536
//     32767.999 --> 32767
//     OverflowException: 32768
//     -0.999 --> 0
//     -1 --> -1
//     -32768.999 --> -32768
//     OverflowException: -32769

open System

      123.999m; 65535.999m; 65536m
      32767.999m; 32768m; -0.999m
      -1m; -32768.999m; -32769m ]

for value in values do
    try
        let number = Decimal.ToInt16 value
        printfn $"{value} --> {number}"
    with :? OverflowException as e ->
        printfn $"{e.GetType().Name}: {value}"

// The example displays the following output:

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

                                  -1d,  -32768.999d, -32769d }

      For Each value In values
         Try
            Dim number As Short = Decimal.ToInt16(value)
            Console.WriteLine("{0} --> {1}", value, number)

         End Try   
      Next
   End Sub

Remarks

You can also convert a Decimal value to a 16-bit 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.
