例外

示例

下面的示例使用 ToInt16 方法将十进制数字转换为 Int16 值。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
' 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

注解

还可以 Decimal 使用赋值运算符将值转换为16位整数 Explicit 。You can also convert a Decimal value to a 16-bit integer by using the Explicit assignment operator. 由于运算符执行收缩转换，因此必须在 c # 中使用强制转换运算符或在 Visual Basic 中使用转换函数。Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.
