此 API 不符合 CLS 規範。

符合 CLS 規範替代方案
System.Decimal.ToInt64(Decimal)

將指定的 Decimal 值轉換為對等的 32 位元不帶正負號整數。Converts the value of the specified Decimal to the equivalent 32-bit unsigned integer.

public:
 static System::UInt32 ToUInt32(System::Decimal d);
[System.CLSCompliant(false)]
public static uint ToUInt32 (decimal d);
static member ToUInt32 : decimal -> uint32
Public Shared Function ToUInt32 (d As Decimal) As UInteger

參數

d
Decimal Decimal Decimal Decimal

要轉換的十進位數字。The decimal number to convert.

傳回

32 位元不帶正負號的整數,等於 d 的值。A 32-bit unsigned integer equivalent to the value of d.

例外狀況

d 是負值或大於 MaxValued is negative or greater than MaxValue.

範例

下列範例會使用ToUInt32方法,將十進位數轉換成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

'     123 --> 123

備註

傳回值是十進位值的整數部分;小數數位會被截斷。The return value is the integral part of the decimal value; fractional digits are truncated.

您也可以Explicit使用指派Decimal運算子,將值轉換成32位不帶正負號的整數。You can also convert a Decimal value to an 32-bit unsigned integer by using the Explicit assignment operator. 因為運算子會執行縮小轉換,所以您必須在中C#使用轉型運算子或 Visual Basic 中的轉換函數。Because the operator performs a narrowing conversion, you must use a casting operator in C# or a conversion function in Visual Basic.
