# Decimal.ToInt16(Decimal) メソッド

## 定義

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

value
Decimal

#### 戻り値

Int16

value と等価の 16 ビット符号付き整数。

#### 例外

valueMinValue より小さいか MaxValue より大きいです。

## 例

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 {

Console.WriteLine("{0} --> {1}", value, number);
}
catch (OverflowException e)
{

Module Example
Public Sub Main()
Dim values() As Decimal = { 123d, New Decimal(123000, 0, 0, false, 3),
123.999d, 65535.999d, 65536d,
32767.999d, 32768d, -0.999d,
-1d,  -32768.999d, -32769d }

For Each value In values
Try
Dim number As Short = Decimal.ToInt16(value)
Console.WriteLine("{0} --> {1}", value, number)
Catch e As OverflowException
Console.WriteLine("{0}: {1}", e.GetType().Name, value)
End Try
Next
