示例

下面的示例使用 ToUInt32 方法将十进制数字转换为 UInt32 值。The following example uses the ToUInt32 method to convert decimal numbers to UInt32 values.

using System;

class Example
{
   public static void Main( )
   {
      decimal[] values = { 123m, new decimal(123000, 0, 0, false, 3),
                           123.999m, 4294967295.999m, 4294967296m,
                           4294967296m, 2147483647.999m, 2147483648m,
                           -0.999m, -1m, -2147483648.999m, -2147483649m };

      foreach (var value in values) {
         try {
            uint number = Decimal.ToUInt32(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
//     4294967295.999 --> 4294967295
//     OverflowException: 4294967296
//     OverflowException: 4294967296
//     2147483647.999 --> 2147483647
//     2147483648 --> 2147483648
//     -0.999 --> 0
//     OverflowException: -1
//     OverflowException: -2147483648.999
//     OverflowException: -2147483649

Module Example
   Public Sub Main()
      Dim values() As Decimal = { 123d, New Decimal(123000, 0, 0, false, 3), 
                                  123.999d, 4294967295.999d, 4294967296d,
                                  4294967296d, 2147483647.999d, 2147483648d, 
                                  -0.999d, -1d, -2147483648.999d, -2147483649d }

      For Each value In values
         Try
            Dim number As UInteger = Decimal.ToUInt32(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

'     4294967295.999 --> 4294967295

注解

返回值为十进制值的整数部分;小数位被截断。The return value is the integral part of the decimal value; fractional digits are truncated.

还可以 Decimal 使用赋值运算符将值转换为32位无符号整数 Explicit 。You can also convert a Decimal value to an 32-bit unsigned 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.
