Decimal.ToInt16(Decimal) Decimal.ToInt16(Decimal) Decimal.ToInt16(Decimal) Decimal.ToInt16(Decimal) Method

定義

指定した Decimal の値を、等価の 16 ビット符号付き整数に変換します。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

パラメーター

value
Decimal Decimal Decimal Decimal

変換する 10 進数。The decimal number to convert.

戻り値

value と等価の 16 ビット符号付き整数。A 16-bit signed integer equivalent to value.

例外

valueMinValue より小さいか MaxValue より大きいです。value is less than MinValue or greater than MaxValue.

次の例ではToInt16 、メソッドを使用してInt16 、10進数を値に変換します。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
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
   End Sub
End Module

注釈

代入Explicit演算子を使用しDecimalて、値を16ビット整数に変換することもできます。You can also convert a Decimal value to a 16-bit integer by using the Explicit assignment operator. 演算子は縮小変換を実行するため、または Visual Basic の変換関数C#でキャスト演算子を使用する必要があります。Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.
